When a magnetic current antenna is parallel to a metal ground, it can produce a nearly 180° 3dB beamwidth in the E plane, which can achieve a wide-angle scanning range in the E plane. But the bandwidth of an equivalent magnetic current antenna is us

Abstract A compact quasi-hemispherical-pattern antenna, two linear wide-angle scanning arrays, and a planar wide-angle scanning array are proposed. To increase the field-of-view scanning range of arrays, a compact low-profile antenna with a quasi-hem
