In this paper, a novel concentric annular-ring slot dual-band CP microstrip antenna that operates at ISM band (2.45GHz) and 5G band (3.5GHz) is proposed and investi-gated. The antenna is a kind of single-layer slot antenna. There are two concentric ring slots of different size on the ground to generate dual-band radiation. The two symmetri- Microstrip‐line‐fed printed shorted ring‐slot antennas for Aug 27, 2001 · Designs of circularly polarized printed shorted annual and square ring‐slot antennas are proposed. 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 DESIGN OF RECONFIGURABLE ANNULAR SLOT ANTENNA … DESIGN OF RECONFIGURABLE ANNULAR SLOT ANTENNA (ASA) FOR WIRELESS COMMUNICATIONS / WLAN APPLICATIONS Radiation patterns of annular slots when n=0 and W s<< ... due to the 3 λs/2 ring circumference, creates a null in the radiation pattern in the direction of the microstrip feed line. To change the direction of the null, short circuits have ...
