Abstract

A circularly polarized conical-beam patch antenna that employs a hybrid feeding mechanism for wideband operation is presented in this paper. It is implemented through using a pair of L-probes and apertures, which are connected by the feeding network, to excite the circular patch in orthogonal directions. The patch is supported by two plastic posts of 0.084 λ₀ height in the air, where λ₀ is the free-space wavelength at 2.53 GHz. This antenna possesses an impedance bandwidth of 28.2% (SWRR < 1.5) and an axial ratio bandwidth (AR < 3 dB) of 28.3%. Also, it has left-hand circularly polarized conical patterns with the peaks located at around θ = ± 33º over these bandwidths. Moreover, its 3-dB gain bandwidth and peak gain are 32.4% and 5.5 dBic, respectively.
