Abstract: The design of a new microstrip-line-fed wideband circularly polarized (CP) annular-ring slot antenna (ARSA) is proposed. Compared with existing ring slot antennas, the ARSAs designed here possess much larger CP bandwidths. US4547779A - Annular slot antenna - Google Patents A microstrip annular antenna structure is formed by four quarter-wavelength microstrip radiator patches arranged in a quadrant formation and having outwardly directed adjacent radiating apertures which together provide a composite annular radiating slot extending about 360° of azimuth. Wideband double-element ring slot antenna - Electronics Letters 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
The other important antenna parameters like direction of maximum radiation, half power beamwidth (HPBW) and radiation conductance are computed, and the results are compared with those of single element MARSA. It is observed that the array geometry is suitable for obtaining a directive beam.
Effect of the Different Shapes: Aperture Coupled Microstrip ... Effect of the Different Shapes: Aperture Coupled Microstrip Slot Antenna 105 Microstrip Feed Line Feed substrate dielectric constant should be in the range of 2 to 10.A thinner feed substrate results in less spurious radiation from feed lines, but higher loss. A compromise of 0.01 λ to 0.02 λ is usually good. Loaded annular ring slot microstrip antenna for wideband and ... In this article, an annular ring slot microstrip antenna loaded with two pie-shaped circular sectors is presented. With the use of pie-shaped circular sectors along the microstrip feed line, a multi-wider-band operation than for a conventional annular ring slot can be realized.
The measured results of the annular-ring slot microstrip antenna show good performance of dual-band circularly polarized characteristics. 1. Introduction. Compared to conventional antennas, the microstrip antenna get easier implementation of dual-band and circular polarization. A novel method of support vector machine to compute the... | Cogent… Annular ring compact microstrip antennas are miniaturized by loading a circular slot in the center of the circular patch. The resonant frequency determination of compact microstrip antennas is important, because these antennas inherently suffer from narrow bandwidth. MARSA - Microstrip Annular-Ring Slot Antenna |… How is Microstrip Annular-Ring Slot Antenna abbreviated?MARSA stands for Microstrip Annular-Ring Slot Antenna. Suggest new definition.
