Abstract :
A new type of bi-layered microstrip antenna (MSA) with conical radiation pattern for mobile satellite communication 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. Thus the element antenna is first coarsely designed and the performance is optimized by electromagnetic simulator at 14.25 GHz. The optimized element antenna has the conical radiation pattern in two orthogonal planes. Using the element antenna, the beam scanning characteristics of 16-element linear array antenna are investigated. The simulated results show that the proposed bi-layered MSA would be suitable for the mobile satellite communications.
