摘要：India is planned to develop a satellite based navigation systems known as Indian Regional Navigational Satellite System (IRNSS) for positioning applications. Design of IRNSS antenna at user segment is necessary. In order to design antenna, a new planar, wideband feed for a slot spiral antenna is designed using HFSS software simulations. This paper describes a spiral antenna on RT DUROID Substrate for the operating frequency range of 1.2 -1.6 GHz These specifications should be satisfied at the frequency L5 (1175 MHz).Array of spiral antennas can be used to increase the gain. Spiral antennas are reduced size antennas with its windings making it an extremely small structure. The antenna uses four spiral elements to provide broadband satellite coverage and can also be used in conjunction with a space- time adaptive processor (STAP) for interference suppression. This paper presents the input impedance, radiation pattern and gain.
