Abstract

A double F antenna (299) comprises a conductive member having a center between a first end and a second end of the member; a first port (204) connected perpendicularly to the conductive member between the center and the first end; a second port (203) connected perpendicularly to the conductive member between the center and the second end; and a ground port (205) connected perpendicularly to the conductive member, wherein the ground port (205) is connected to the center.
