A new type of wide beamwidth antenna is proposed for mobile satellite communication systems. The microstrip crossed slot antenna consisting of four shorted quarter wave elements is one of the antenna elements of wide beamwidth. To widen the beamwidth still further, the antenna installed on a pyramidal ground plane is presented in this letter. The radiation pattern of this antenna is also measured and discussed.
