In this paper, a 4.2–7.2 GHz (52.6%) beam-steering microstrip antenna was proposed. The proposed consists of three tapered slots and feeds. radiation directions the on plane are independent each other, feeds correspond to structures. Symmetry isolation trenches introduced improve between different ports. Radiation pattern simulation measurement show horizontal beam steering at sampled frequenci...

This paper introduces novel dual-polarized/duplex filtering antennas with a feeding network. The network consists of an all-resonator structure, which shares common dualmode resonator. structure facilitates the isolation two well-isolated channels through exploitation even and odd modes dual-mode By applying balanced excitation to mode unbalanced mode, can be separated, creating hybrid-like str...
