Abstract
An antenna arrangement comprises a patch conductor (102) supported substantially parallel to a ground plane (104) and a feed conductor (106) connected to the patch conductor. Such an arrangement is similar to a conventional Planar Inverted-F Antenna (PIFA), but lacks the additional grounding conductor connected between the patch conductor and the ground plane in known PIFAs. Elimination off this grounding conductor enables matching to be performed by external circuitry, thereby enabling a better match to be achieved and enabling similar performance to conventional PIFA antennas to be achieved from a reduced volume. These advantages are particularly apparent for dual-band (or multi-band) operation, where the use of a dual-band matching circuit allows a much smaller end less complex antenna to be used.
Claims8
A planar inverted L-antenna, comprising a substantially planar patch conductor supported substantially parallel to a ground plane and a feed conductor connected to the patch conductor, wherein the patch conductor is electrically insulated from the ground plane at operational frequencies of the antenna arrangement and wherein a matching network is connected between the feed pin and the ground plane to provide a match to the planar inverted L-antenna at a plurality of discrete frequencies.
