Wideband double-element ring slot antenna N. Behdad and K. Sarabandi A new technique for bandwidth enhancement of microstrip-fed annular ring slot antennas is presented. Using this technique, a wide-band antenna is designed that has consistent radiation parameters across the entire band and has a bandwidth that is six times larger than Microstrip‐line‐fed printed shorted ring‐slot antennas for ... 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 ...

SINGLE-FEED CIRCULARLY POLARIZED ANNULAR SLOT ANTENNA FOR ... annular slot antenna is obtained by employing two square slots, a bended microstrip line and a cavity back. Dual-band CP radiation can also be achieved by using a spiral slot [13], or a CPW-fed annular slot with two perturbation strips [14]. In [15], a square microstrip patch antenna embedded with four slots and a crossed slot can generate Bandwidth enhancement of L-probe proximity-fed annular ring ... Bandwidth Enhancement of L-Probe Proximity-Fed Annular Ring Microstrip Slot Antenna A. K. Singh, (Research Scholar) Ravi Kumar Gangwar Binod K. Kanaujia Electronics Engineering, Electronics Engineering, Electronics and Commn. Annular Ring Patch Antenna for Wearable Applications Annular ring microstrip antenna is an alternat[3] to standard e rectangular and circular microstrip antennas. The main advantage of annular ring geometry over other microstrip antenna geometries is that for operation at a given frequency in the fundamental mode, the annular ring antenna occupies the smallest physical area.
A simple structure concentric annular-ring slot dual-band circularly polarized (CP) microstrip antenna operating at ISM band (2.45 GHz) and 5G band (3.5 GHz) is proposed in this paper. The antenna achieves dual-band operation by digging two concentric annular-ring slots on the ground. And on the angular positions with 45 degrees inclined of each annular slot, two bent structures are loaded to
