Ultrawide Band Tightly-Coupled Aperture Magneto-Electric Dipole Array Over 20 - 40 GHz

摘要

We propose a linearly-polarized wideband phased-array for millimeter-wave applications. The array is composed of tightly-coupled Magneto-Electric Dipoles fed by slot-coupled microstrip lines. The integration of the radiating elements with the feed structure removes the need of an external balun and simplifies the manufacturing process. The simulated antenna provides 64% bandwidth at VSWR 2 and 60% bandwidth at VSWR 2.65 for scanning up to 45° and 60° in both Eand H-planes, respectively.
