A coax-feed low profile dual-polarized circular patch antenna with high impedance surface (HIS) reflector is presented. The proposed antenna contains two pairs of H-shaped slots on the two bow-tie shaped patches separately, which keep the cross polarization under −39 dB. By introducing two short pins, the isolation between the two ports remains more than 40 dB in the whole bandwidth. Low profile and...
A novel approach to design a pattern reconfigurable antenna element to extend the scanning range of phased array by adjusting the exciting amplitude of vector antenna is presented in this paper. A 2D and 3D vector antenna composed of orthogonal electric dipoles are simulated using CST software. Simulation results demonstrate the correctness of this approach.
