Radiating and Balanced Mode Analysis of PIFA Antennas

psf135

Abstract—This paper presents a radiating and balanced mode
analysis of planar inverted F antennas (PIFAs) mounted on wave-
length-scale printed circuit boards (PCBs). The radiating mode
shows, in a direct way, the extent to which the PCB influences
both radiation and bandwidth. The balanced mode shows that the
shorting pin acts as an impedance transformer in combination with
a parallel reactance. Importantly, it can also be used to show that
slots in the PIFA top plate nominally provide series reactance when
the slot opening is close to the feed. Understanding of this behavior
allows bandwidth improvements to be realized. It also allows dual-
band antennas to be designed in a straightforward manner.
