Abstract

To fulfil the wireless and ISM band medical communication applications, a design of frequency reconfigurable circular patch antenna is presented in this paper.

Three circular rings and small circle are implanted inside the patch with overall dimensions of 50mmx50mm to realize triple band operation.

Finite element method based Ansys HFSS is used to design and simulate the model.

The designed antenna is suitable for PCS, WLAN and X-band applications. Therefore, it covers L-band (1.85–2.1GHz) for PCS, WLAN (5.8–6.7GHz) and X-band (10.3–11.6GHz) for satellite and space research applications.

Reconfigurability, in frequency bands are obtained by placing four PIN diodes inside the circular patch. The constructed antenna shows reliable radiation patterns, good impedance characteristics.
