Abstract

This paper presents a new reconfigurable microstrip feed patch antenna. The reconfigurability allows the antenna to carry communications over different WLAN band frequencies (2.4 GHz, 3.6 GHz, 4.9 GHz, 5 GHz, and 5.9 GHz). It mainly consists of microstrip feed-line and a circular radiating element that is divided into three patches, which are being reconfigured / switched, by the use of silicon PIN diodes. PIN diodes are chosen for achieving reconfigurability as being more practical due to their high switching capabilities. A DC bias tee is used to control the PIN diodes. A prototype of the antenna was manufactured and tested to verify the results.
