Simple mathematical analysis of Triangular Grid Hexagonal Aperture Phased Antenna based on vector analysis is presented. This analysis is used to get on a method to model this configuration, Array Factor, beam steering and grating lobe diagram expression. The correctness of this model is shown by using it for an array with arbitrary number of elements. The best feature of this method is a simple implementation of beam steering and grating lobe diagram, simultaneously.<\div>

An X–band, dual mode, reciprocal, ferrite phase shifter has been developed whose electrical performance issuited for use in a space–fed lens array antenna. A ferrite rod located at the center of a circular waveguide, is used as a Faraday rotator. If a linearly polarized wave passes through this rod, a reciprocal phase–current characteristic is obtained. This phase shifter is designed for the 9.5 GHz center frequency. Best features of this phase shifter are minimum insertion loss, simple structure, small size and simultaneously having a large bandwidth.<\div>
