Abstract

The multi-band antenna is one of the most important elements and commonly used in modern wireless communication. It is incorporated into many multimode receiver designs.WiMax and WiFi are widely applied in wireless device such as femtocell access point. In this paper, a design of reconfigurable rectangular microstrip patch antenna is presented. The antenna is used in WiMax with centre frequency at 3.5 GHz and WiFi (WLAN) with centre frequency at 5.2 GHz. The rectangular microstrip antenna consist the RF-4 proxy in substrate with dielectric constant 4.3 and size (50 × 55 × 1.6mm<sup>3</sup>), and also consist copper with thickness 0.035mm in the patch and ground plane. The design technique based on C-slot on the patch and two parallel slit on the ground plane. Antenna reconfigurability is achieved by three PIN diode switch in C-slot. However, the changes of PIN diode cases status on ON or OFF mode, the resonant frequencies can be changed between 3.5GHz and 5.2GHz. This antenna offers low profile, wide bandwidth and high gain for all frequencies. The performance of the antenna simulated by CST microwave studio simulator and having good results such as return loss -19 dB, -26 dB and bandwidth 56MHz, 132 MHz at 3.5GHz and 5.2GHz respectively.
