  • Abstract
    The authors present the design technique and the measured results of a planar circularly polarized microstrip patch array composed of 4/spl times/4 patches for space applications at S-band. A comparison of the two array configurations shows that the use of hybrid power splitters improves the return loss and the peak axial ratio but drastically reduces the antenna efficiency. The improved array configuration keeps high efficiency over a wide frequency band.<>
