Design Of Multi-Band Reconfigurable Square Spiral Antenna For WLAN & GPS Applications
In this paper, a reconfigurable square spiral antenna has been designed. This antenna is designed for two bands,
Band-1 is 1 GHz to 2 GHz which covers mobile services, satellite navigation, telecommunications use, aircraft surveillance,
amateur radio, Multipoint Communication System, GPS, Satellite communication…etc. and Band-II is 2 GHz to 4 GHz
which covers satellite communications, 802.11b, 802.11g standards, amateur radio and satellite and optical communications.
The antenna can be tuned to other aerospace and EW applications as well. This antenna structure offers a good radiation
efficiency. This has high gain and directivity.
