A wide-angle scanning reconfigurable beamsteering parasitic patch array antenna is introduced in this paper. For beam-steering antennas using microstrip, the beam scanning range is very limited where the typically achieved scanning is in the range of −30° to +30°. Increasing the parasitic elements does not provide significant improvement in terms of the beam scanning where only additional 3° to 5°...

Adaptive beam steering antenna has been develop in this research. The proposed antenna is capable to steer the radiation pattern to phi of 0°, 45°, 135°, 225° and 315° angles and theta of 0°, 13°, 15°, 10° and 12°. This could be achieved with the suitable design antenna based on the patch yagi-uda antenna concept with a single radiator and four parasitic elements. Such four elements is control by...
This paper investigates the effect of isolation loss (ISO) towards the beam steering capability of a parasitic patch array antenna. Parasitic patch antenna is mainly used to steer the main beam towards a desired direction and suppress the signal in unwanted directions. In such a scenario, the ability to steer the beam with reduced side lobe level is considered important to enhance the signal reception...
A switchable parasitic patch antenna that has a capability to operate in four beams of operation is proposed. The presented antenna is developed with a single main radiator at the center of the antenna structure surrounded by four parasitic elements. It has a full ground plane functioned as a reflector that helps to boost the gain up to 8dBi. Antenna reconfiguration is achieved with the implementation...
A beam steering compact patch antenna with high gain application is invented. The proposed antenna is capable to steer the beam radiation to 45°, 135°, 225° and 315°. This is realized in the unique form of single main radiator and four parasitic elements. The activation of the parasitic required a shorting pin to the ground that indicates ON state condition and the deactivation of the parasitic means...
