Summary:
A direction controlled reconfigurable antenna that has four switchable operating modes is presented. The direction of the main radiation beam can be changed from 0° to 180° at 45° angular steps in the azimuth plane. The proposed antenna consists of two flared radiators, truncated ground plane and two parallel strips near its edges. It is controlled using four PIN diodes. The antenna operates across the frequency range from 1.93 to 2.74 GHz to support Bluetooth, WiMax, WLAN and many other wireless services. The antenna has narrow radiation beams in the azimuth planes for reasonable selectivity and wide beams in the elevation plane for wide coverage. The designed antenna has a simulated peak gain of 3.5 dBi and simulated average gain of more than 2 dBi over the covered band. Despite using a simple structure and controlling mechanism, the antenna represents a suitable candidate compared to other antenna designs operating at the same frequency band. It has a compact dimension of 38 × 48 × 1.6 mm3 using FR4 substrate.
