Abstract

A circularly polarized double-stacked patch subarray hexagonal antenna fed by a radial line with internal circular coupling patches is proposed. The antenna works in K band (19.7 GHz - 20.2 GHz) with LHCP. The design approach consists of a coupling study based on the simulation of a periodic parallel-plate waveguide as a first approximation of the radial line. A phase compensation method by rotation is applied to adjust the radiating phase of each element of the subarray, which are separated 0.7 lambda(0). The subarray is uniformly fed in terms of amplitude and phase. An axial ratio below 1 dB is achieved for the entire frequency band, with a gain of 24 dB and a total efficiency of 87%.
