Millimeter-wave printed antenna arrays for covering various sector widths - [Antenna Designer's Notebook]

We introduce new millimeter-wave corner antenna arrays (MWCA) with eight axially placed printed dipoles fed by an integrated symphase network. The antenna array is placed between two metal plates that make the corner reflector. The antennas were simulated and realized in the frequency range about 26 GHz, which is popular for microwave communication networks. Three antennas, with different H-plane beamwidths (intended for azimuth) of 55', 1100, and 1800, were investigated, simulated, and realized. The bandwidths of all of the antennas were wider than 12%. The losses in all of the antennas were less than 1 dB. The agreement between simulated and measured results was very good. Millimeter-wave corner antenna arrays are low in cost and very simple to realize, and are also suitable for integration.
