Circular polarization (CP) radiation of the shorted ring‐slot antennas is achieved by selecting a proper length of the shorted section in the ring slot, which is about 3.9 and 8% of the mean circumference of annular and square ring slots, respectively, and feeding the ring slot using a microstrip line 90° to the shorted section. Circular Patch loaded Annular Ring Microstrip Antenna ... In this paper, circular patch loaded annular ring microstrip patch antenna using L-probe feed and orthogonally slot loaded at the inner periphery of the driven ARMSA is investigated, the effect of the variation in the horizontal probe length and height of the circular patch and is also analyzed. Simulated DESIGN AND INVESTIGATION OF A DUAL-BAND ANNULAR RING SLOT ... difierent operation modes compared with annular ring slot antennas are introduced [18,19]. In this paper, we propose a new dual-band annular ring slot antenna. The antenna is based on an annular ring slot antenna that is shorted concentrically with a set of conductive vias.
