Patch antenna, wideband antenna, folded patch feed, and
This paper presents a novel compact patch antenna with a
folded patch feed and shorting walls. Bandwidth
broadening is achieved by an E-H shaped patch fed by a
folded patch feed and the size reduction is realized
through the use of shorting wall. A stacked technique is
introduced to further enhance the impedance bandwidth.
The proposed antenna exhibits impedance bandwidth of
more than 80% for return loss 10dB (VSWR ≤ 2). The
compact antenna dimension is 0.317λg x 0.317λg x 0.317λg
(where λg is the guided wavelength of the center operating
frequency). The impedance matching, radiation patterns
and gain curves are illustrated. Owing to its wideband and
low-profile characteristics, it is highly suitable for ultra
wideband technology (UWB).
