Abstract

In this paper a 140 GHz circularly polarized antenna is studied. The motivation of this work is to propose a suitable antenna configuration to reduce the subsequent manufacturing cost and complexity. The resultant antenna consists of a circular waveguide feed and a dielectric cover which is used to increase antenna directivity. Numerical study shows that the proposed antenna exhibits a 17% relative S11 bandwidth with a maximum gain of 16 dBi. The axial ratio is less than 3 dB ranging from 130 GHz to 155 GHz.
