Abstract: A new design of a microstrip-line-fed circularly polarized printed ring slot antenna is proposed. Circular polarization (CP) radiation of the proposed design is achieved by introducing proper asymmetry in the ring slot structure and feeding the ring slot using a microstrip line at 45/spl deg/ from the introduced asymmetry. A Novel Concentric Annular-Ring Slot Dual-Band Circularly ... In this paper, a novel concentric annular-ring slot dual-band CP microstrip antenna that operates at ISM band (2.45 GHz) and 5G band (3.5 GHz) is proposed and investigated. 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. DESIGN AND INVESTIGATION OF A DUAL-BAND ANNULAR RING SLOT ... analyze the annular ring slot antenna for the TM modes [20]. In this analysis, the feeding line is not considered. Here, we only consider the TM0m modes in the annular ring slot antenna, since only the TM0m modes can produce a monopole like radiation pattern. For the TM0m modes, the fleld inside the structure must be symmetric about the z axis.
The design of a microstrip‐fed annular‐ring slot antenna (ARSA) with circular polarization (CP) radiation is initially studied. To obtain CP radiation with broad 3‐dB axial ratio (AR) bandwidth that can cover the WiMAX 2.3 GHz (2305–2320 MHz, 2345–2360
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 SINGLE-FEED CIRCULARLY POLARIZED ANNULAR SLOT ANTENNA FOR ... 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 dual-band CP radiation. But all these designs in [13{15] have a limited A NOVEL DESIGN OF A MICROSTRIP- FED SHORTED SQUARE-RING ... 4.3% for annular and square ring-slot, respectively. In addition, the 2 2 ring-slot antenna array with a 3-dB AR bandwidth of 15% is presented in [4], but the frequency of the minimum AR value is not the same as the fundamental resonant frequency. In this article, we propose a novel design of CP slot antenna to Design and Analysis of Annular Ring Slot MSA for wireless ... Abstract— In this paper the design and analysis of annular ring slot microstrip antenna is presented. The design frequency of antenna is 2.1 GHz and used substrate for the fabrication of the proposed antenna is FR4. After simulation and testing return losses of about -14 dB, -14 dB, -19 dB and -10 dB
