A low profile, wideband cavity‐backed bowtie antenna

In this article, an annular-ring slot antenna was investigated, which showed variable and wide impedance bandwidths, achievable by optimizing different antenna parameters. The measured impedance bandwidth and 3-dB ARBW of the proposed antenna are 94.2 and 73.8%, respectively. The measurements on the fabricated antenna showed good agreement with the simulated data. This antenna may find applications in wireless communication, where simple wideband and compact circular polarized antenna is desired.
