Abstract

A size reduction technique for the planar inverted-F antenna (PIFA) is presented. An 18 nH lumped inductor is used in addition to a small 0.3 cm3 PIFA. The PIFA is located on dielectric foam, 5 mm above a 40 mm × 100 mm ground plane. It is possible to reduce the center frequency (|S11|min) by 33 percent for a fixed physical size. The measured – 6 dB bandwidth is 6.7 percent with a peak radiation efficiency of 88 percent.
