Design and analysis of an electrically steerable microstrip antenna for ground to air use

Abstract [en]

A single-feed circularly polarized microstrip antenna array, operating at 2.45 GHz, have been analyzed and designed. The antenna is mainly intended to be used for reception of a video signal transmitted from an unmanned aircraft, but can be used for other applications as well. Due to the fact that it is supposed to be used in a switched system, the beam width is quite narrow. Measurements of the antenna shows that it have a half power beam width of 40 degrees. For a VSWR lower than 1.5 and an axial ratio lower than 3 dB the band width is 80 MHz centered at 2.44 GHz. The side lobe levels are lower than -23 dB. The antenna is designed to be simple in layout due to the fact that it should be as robust as possible against manufacturing faults.
