This is a synopsis of work conducted to improve the electrical and mechanical performance of antennas used for mobile communication base stations. To accomplish this we first consider the propagation characteristics to determine the optimal antenna pattern. In addition, the antennas mechanical size and profile are minimized to improve its appearance and mounting ease. The end result of this work is an antenna that has superior performance in terms of virtually every antenna and mechanical specification. This was achieved by the use of a specially constructed microstrip patch element in conjunction with technology for beam shaping and the use of environmentally proven materials. The present use for such antennas is for the 900MHz GSM and 1.8GHz PCN systems base stations but freedom in the design frequency range, polarization, and array configurations allow for a considerably wider range of applications.
