Omnidirectional Circularly Polarized Monopole Antennas on Artificial Magnetic Conductor Ground Plane
Publikováno v:
IEEE Access, Vol 12, Pp 81567-81580 (2024)
This research proposes omnidirectional circularly polarized monopole antennas (OCPA) with single-annular (SA-AMC) and dual-annular artificial magnetic conductor (DA-AMC) ground planes. The aim of the proposed antenna scheme is to circumvent the desig

A conical cavity-backed antenna with embedded multiple quarter-wave resonators (multiple QWRs) is proposed. The 3-dB axial ratio bandwidth (ARBW) of a cavity-backed antenna is limited by cavity resonance, undesired cavity current, and circular polari
