In this paper, an antenna with a cosecant squared pattern to work as a radiating vertical array of SSR antennas is designed. A simple microstrip structure is a dopted to design as feed network and 11 half-wave dipoles are selected as radiating elements. In order to achieve desired pattern, amplitude and phase of elements are obtained using a synthesis pattern method. Equal and unequal Wilkins on power dividers are used to prepare desired power amplitudes to feed the elements. The designed antenna has nearly 10 dB gain and its main beam in the elevation plane is 9 degrees above the ground. Its −10 dB Beam width in elevation pattern is 50 deg. and return loss in central frequency is 22 dB. A one element and a two element array are fabricated on RT Duroid5880 (εr = 2.2 and tan δ = 0.0009) with thickness of 31 mil and measured to investigate verification between simulation and measurement and considering mutual coupling.
