Abstract

A new planar, wideband feed for a slot spiral antenna is presented 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 frequencies of 1.227 GHz (L2) and 1.575 GHz (Ll). 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.. This paper presents the return loss, gain, radiation patterns and VSWR.The analysis is based on the results of the simulations obtained using the software Ansoft HFSS.
