A series-fed E-shaped patch antenna array has co-polarized parasitic patches to improve aperture efficiency. Each of microstrip parasitic patches is inserted between a plurality of microstrip E-shaped patch antennas. The parasitic patches are co-polarized with the E-shaped patch antennas so that ...
A reconfigurable patch array antenna exhibiting circular polarization as well as pattern switching capabilities is presented in this work. The proposed 2 x 2 series-fed structure is capable of generating 11 switched beams at a resonant frequency of 2.44 GHz. The work also hypothesis an ...
