Abstract

This paper presents a linear antenna array system with a compact corporate feed network. The antenna elements are probe fed circularly polarized microstrip patch antennas. By using probe feed topology, it is possible to combine all the antenna elements on the backside of the array. Besides, the overall size of the feed network is reduced with the proposed special corporate feed topology. An 8×1 linear array is designed and produced as the building block of a larger 2D array. The antenna array's return loss, radiation pattern and polarization characteristics give good agreement with the numerical calculations.
