- Abstract
A new dielectric rod antenna (DR ) is introduced to produce circular polarization (CP) over a wide frequency band without a complex feed network. long with the simulated results, measured results of the antenna prototype are presented, showing a 3 dB axial ratio (AR) CP bandwidth of 17.7%. The radiation characteristics of the fabricated antenna are also demonstrated showing the measured gain of better than 6.2 dBi. Moreover, the measured impedance bandwidth (VSWR ⩽ 2) reaches 20.1%, from 8.75 GHz to 10.7 GHz, while the CP beamwidth (AR ⩽ 3 dB) at the central frequency is measured over 120?
