Abstract :
In this article, the development of a circularly polarized microstrip array with 28 dBic of gain at 32 GHz is presented. Two primary objectives of this development are minimizing the microstrip array´s insertion loss and maintaining a reasonable frequency bandwidth (3%). The parallel/series feed technique for the array´s power distribution circuit and the sequential rotation method for the element arrangement are employed to meet these objectives
