A new type of bi-layered Micro-Strip Antenna (MSA) with conical radiation pattern for mobile satellite communications is proposed as an element antenna in this paper. The MSA consists of three patches with slots on bi-layered substrate and the feed is passing through the ground of the substrate. Firstly, the element antenna is designed as transmitting antennas for mobile station of satellite communications. The performance of the antenna is investigated by electromagnetic simulator. The designed element antenna has the conical radiation pattern in two orthogonal planes and the gain of main beam direction, plus or minus 40, with 4dBi.
