Description

A RADIO ANTENNA ASSEMBLY
Technical field of the invention
The present invention relates to a multidirectional radio antenna assembly, comprising a plurality of elongate, substantially vertical antenna elements, arranged circumferentially around a vertical axis, said antenna elements having a lower end attached to a lower support member, and an upper end attached to an upper support member.
Background of the invention
A known type of radio antenna assembly for so-called DAN (Dect Access Node) applications is usually mounted on a mast at radio telephone base station sites and includes a plurality of (often six) elongate vertical antenna elements, evenly distributed circumferentially around a vertical axis in order to obtain an omnidirectional antenna assembly covering surrounding DAN-subscriber sites. Such antenna assemblies are suitable for transmitting and receiving digital radio signals at DAN- sites having a substantially uniform spread of subscribers within the sites. However, when the subscribers are spread more unevenly within various DAN-site sections around such omnidirectional radio antenna assemblies, transmission congestions may arise due to limited transmission capacity of active antenna elements being able to be focused on such "crowded" DAN-sites. Therefore, a greater number of such antenna assemblies, and hence a greater number of masts, transmission equipments etc., are required to obtain an acceptable service level within such DAN-sites.
Summary of the invention
An object of the present invention is to provide an adjustable, multidirectional antenna assembly of the initially described type, which eliminates the above- mentioned drawbacks of the previously known radio antenna assemblies and which allows for antenna element adjustments such that at least a plurality of the antenna elements of the assembly may be focused or directed towards more subscriber- densed areas.
According to the present invention, this object is achieved by a radio antenna assembly of the type referred to above, which is characterized in that at least some of the antenna elements are individually rotatably adjustable about at least one vertical axis in their respective support members.
Most preferably, the rotatably adjustable antenna elements are adjustable about either one of two circumferentially separated vertical axes. In a six-antenna element assembly, this may allow for a ±60° individual rotational adjustment of each element without creating interference disturbances of the signal lobes emitted from the antenna elements.
Further features of the antenna assembly of the present invention are defined in the dependent claims.

Description of a preferred embodiment
An adjustable multidirectional radio antenna assembly according to the present invention is generally denoted 10 in Fig. 1 and comprises six elongate, substanti- ally vertically extending antenna elements 12a- 12f, circumferentially separated around a vertical mast member 14. The antenna elements 12a- 12f are carried at their lower ends by a lower support member 16, and at their upper ends by an upper support member 18.
As seen in Fig. 2, each support member 16,18 has the shape of a polygonal plate with a tubular hub portion 20 to be mounted on the mast member 14 and secured thereto by means of a fixating screw 22 or the like. Fig. 2 shows the lower support plate 16 from below and the upper support plate 18 from above.
Each plate 16, 18 has two pairs of diametrically opposite holes 24,~26 for stationary fixation of the respective ends of two non-rotatable (stationary) antenna elements 12a, 12d (see Figs. 1, 5 and 6). Furthermore, each support plate 16,18 has four pairs of mounting holes 28, 30, 32 and 34 for attachment of four "iron-shaped" turn- plates 36, each adapted to carry a respective end of an antenna element 12b, 12c, 12e and 12f rotatably adjustable by means of the tumplates.
As seen in Figs. 3 and 4, each turnplate 36 has a pair of mounting holes 38 for fixation of an end of a respective rotatably adjustable antenna element, and two curved arrays of angle adjustment holes 42a-42g and 44a-44g. In a middle or neutral position (Fig. 4) the tumplates 36 are fixed to the respective support plates 16,18 by pins or screws 46 in the holes 42a and 44a of the tumplates 36 and the mounting holes 28, 30, 32 and 34 of the support plates 16,18. Since the holes 42a-42g in the one curved array of holes are located on a fixed radius R from the hole 44a in the other curved array of holes, and the holes 44a-44g of said other array of holes are located on the same radius R from the hole 42a in said one array of holes, the turn- plates 36 may be angularly adjusted about either one of the holes 42a and 44a. The holes 42a-42g and 44a-44g in each array of holes are angularly separated 10°, which means that the turnplate 36 can be adjusted up to ±60° relative to the support plate 16, 18 with respect to the neutral position.
As best seen in Fig. 5, the lower end of each rotatably adjustable antenna elements 12b, 12c, 12e, 12f carries a L-shaped bracket 47 on which is mounted a first U-shaped hinge member 48, which is journalled about a horizontal pivot pin 50 fixed to a second U-shaped hinge member 52. The second hinge member 52 is mounted to a further L-shaped bracket 54, which is fixed to the turnplate 36 by means of screw and nut means 56 through the holes 38. The hinge assembly 48,50,52 allows for the antenna elements 12a- 12f to be tilted about the horizontal pivot pin 50 from a substantially vertical position (not shown) to an approximately 20° downwardly inclined position (Figs. 1, 5, 6 and 7). To allow for said 20° tilted position, the upper ends of the antenna elements 12a- 12f are connected to the upper support plate 18 by means of a link mechanism, such as a toggle joint 58 comprising a first lever 60 pivoted to a L-shaped bracket 62 at the upper end of the antenna elements 12a- 12f about a horizontal axis, and a second lever 64 pivoted about a horizontal axis relative to the upper support plate 18, and hinged to the first lever 60 about a horizontal pivot pin 66. A scale 68 of tilt degrees may be provided at the pivot pin 66 to indicate the actual tilt angle of the antenna elements 12a- 12f relative to the horizontal.
In the preferred embodiment of the present invention, the adjustable antenna assembly 10 comprises six antenna elements 12a- 12f, although a lesser or a greater number of antenna elements may be provided in each assembly. In the configuration shown in Fig. 6, all six antenna elements 12a- 12f (only four are visible) are mutally separated 60° around the mast member 14 and tilted 20° towards the horizontal, i.e. the tumplate 36 of the four adjustable antenna elements 12b,12c,12e and 12f are secured to the respective support plate 16,18 by means of the screws 46 inserted through the holes 42a,44a (Fig. 3). In this position of the tumplates 36, and thus of the stationary and adjustable antenna elements 12a- 12f, the antenna assembly 10 is omnidirectional. However, the angular positions of the tumplates 36 may be adjusted so as to set the antenna elements in many different rotational positions. For example, as seen in Figs. 1 and 5, the adjacent pairs of tumplates 36 may be pivoted 30° about adjacent ones of the adjustment holes 42a,44a (Fig. 3), thereby setting the antenna elements 12b and 12c as well as the antenna elements 12e and 12f in parallel with each other, such that the assembly 10 will have one stationary antenna element 12a in a Opposition, two adjustable antenna elements 12b and 12c in a 90°- position, one stationary antenna element 12d in a 180°-position, and two adjustable antenna elements 12e and 12f in a 270°-position.
In the configuration shown in Fig. 7, the antenna elements are oriented bidirection- ally, i.e. the adjustable antenna elements 12b and 12f are rotated 60° from their middle position towards the adjacent stationary antenna element 12a, while the adjustable antenna elements 12c and 12e are rotated 60° from their middle position towards the adjacent stationary antenna element 12d, thereby forming a bidirectional antenna assembly 10 having two opposite groups of three adjacent and co- planar antenna elements. All antenna elements may, of course, take an individually adjusted tilted position.
Two or more adjustable, multidirectional antenna assemblies of the present invention may be combined in order to properly cover specific DAN-subscriber areas, to maintain a desired service level. The antenna assemblies may thus be mounted above each other on one and the same mast, or on adjacent masts.
