Design of an Antenna for Mobile Satellite Services

R. Brinda ^[4] | E. Nisha Flora Boby

Abstract: In this paper, a miniaturized S-Band antenna for Mobile Satellite Services (MSS) with near Omni-directional coverage is designed for Mobile hand-held Terminals. Mobile Satellite Services is used for communication services between Mobile Earth Stations (MES) and space station during several disasters such as flood, hurricanes and earthquake. Four Hexagonal patch antenna surrounded by a square ring with a superstrate structure is designed to operate in dual frequency range with a single feed. The proposed antenna has V- shaped slots to tune the antenna for achieving both uplink and downlink frequencies. The Slotted Hexagonal patch antenna resonate at centre frequency 1.99GHz and 2.18GHz. The simulation has been performed by using Ansys HFSS, which is a Finite Element Method (FEM) based Electromagnetic Solver. A low cost and readily available FR-4 substrate of relative permittivity of 4.4 and height 3.2mm has been used and fed with 50 microstrip line.
