In [12], dual-band circularly polarized annular slot antenna is obtained by employing two square slots, a bended microstrip line and a cavity back. As shown in Figure 2(a), antenna 1 is a fold annular slot antenna , and the asymmetric of the slot width will lead to two split orthogonal degenerate modes around 2. An Introduction of Aperture Coupled Microstrip Slot … An aperture-coupled design is proposed for Microstrip slot antenna to improve its radiation pattern as well as bandwidth. It is based on coupling of an aperture between the patch antenna and Microstrip slot line. The first aperture coupled microstrip antenna was introduced in 1985 by D M Pozar (4) Figure1: Aperture coupled microstrip slot antenna DESIGN OF RECONFIGURABLE ANNULAR SLOT ANTENNA (ASA) FOR ... The annular slot antenna consists of a circular slot on a square, metal ground plane that is fed by a microstrip line, designed on the bottom of the Duroid substrate. The mean length of the slot circumference is approximately 3 λs/2 at the frequency of 5.8 GHz
Aperture Coupled Microstrip Antenna Design and Analysis
The annular slot antenna consists of a circular slot on a square, metal ground plane that is fed by a microstrip line, designed on the bottom of the Duroid substrate. The mean length of the slot circumference is approximately 3 λs/2 at the frequency of 5.8 GHz Axial-Ratio-Bandwidth Enhancement of a Microstrip-Line-Fed May 10, 2011 · 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. The main features of the proposed design include a wider ring slot, a pair of grounded hat-shaped patches, and a deformed bent feeding microstrip line. Polarization Reconfigurable Eccentric Annular Ring Slot
A compact annular ring microstrip antenna was proposed for a wireless sensor network (WSN) application in the 2.4 GHz band. In this paper the major considerations of the conformal antenna design were the compact size and the impact on antenna's performance of a steel installation base. By using a ...
