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...
A reconfigurable beam shaping of quadratic‐aperture coupled antenna array is introduced. The 16 rectangular patches microstrip antenna is fed by an aperture coupled structure, which incorporates PIN diode switches that are integrated with the feed line. The activation of certain PIN diode switches configuration enables the variety outcomes of the radiation patterns with different beamwidth and gain...
