Microstrip antennas, such as microstrip patch and slot antennas are found attractive for use in manyRing-slot antennas, which have a better bandwidth than microstrip patch antennas, have also been developed [1–3].experimental study of a cavity-backed annular-slot. antenna, IEE Proc.
Annular Slot Loaded High-Impedance Ground Plane - ECE/CIS A conventional slot ring without a grounded dielectric will radiate at a frequency determined by the guided wavelength of the slot. That is, an annular slot antenna will radiate its fundamental mode at a slot radius of [2] Annular Slot Loaded High-Impedance Ground Plane Broadband Circularly Polarized Annular-Ring Microstrip ... Abstract: A wideband circularly polarized (CP) annular-ring patch antenna with two proximity-coupled L-probe feeds orientated to have phases of 0 deg and 90 deg, using a broadband 90 deg hybrid feed, is proposed. It is found that the current distribution for CP operation can be improved by cutting a smaller concentric circular slot on the original larger circular patch to form an annular-ring ... DESIGN OF RECONFIGURABLE ANNULAR SLOT ANTENNA (ASA) FOR ... The annular slot antenna consists of a circular slot on a square, metal ground plane that is fed by a microstrip line, designed on the bottom of the Duroid substrate. The A Circularly Polarized Annular-ring Patch Antenna with a ...
