For the first time, integration of a commercial single-pole four-throw RF switch with beam steerable square loop antenna is presented. By controlling the switch bias the high gain tilted beam of the antenna can be steered electronically in all the four space quadrants. A model of the complete integrated switch with the antenna has been developed and simulated. Further, for achieving distortion-free...
A beam steerable square loop antenna over hybrid high impedance surface is designed and simulated with the help of Agilent ADS momentum and its benefit in increasing the Wi-Fi range and speed is demonstrated. At a test frequency of 4.7 GHz, the antenna produces a tilted beam in the direction of Φmax = 315° and θmax = 30° with 8 dB gain. Compared to conventional laptop antennas, the proposed antenna...
A novel hybrid high impedance surface is presented and a beam steerable four feed square loop antenna is built on this structure. At a test frequency of 4.7 GHz, the proposed hybrid high impedance surface based square loop antenna is 4.69 mm high and has an impedance bandwidth of 650 MHz and directivity of 8.7 dBi. Compared with the earlier reported steerable square loop antenna the new antenna s...
