PIFA input bandwidth enhancement by feed structure

gaxchen

2.45 GHz planar inverted-F antenna (PIFA) designs mounted on a
100 mm square ground plane are examined with regard to the feed element
shape influence on the input bandwidth (BW). While the
traditional wire-fed PIFA has a BW from about 4 to 12%, the novel
PIFAs with diverse feed plates (triangular, bi-triangular, rectangular,
rounded-rectangular and U-strip) are designs capable of a much
broader BW, between 18 and 25% for some configurations.
