DESIGN OF RECONFIGURABLE ANNULAR SLOT ANTENNA … 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 Jun 10, 2015 · Abstract: A microstrip-fed reconfigurable eccentric annular ring slot (EARS) antenna with switchable polarization is proposed. To generate orthogonal circular polarization (CP) radiations, two identical perturbation slots (PSs) are loaded below the eccentric ring-shaped slot. Bandwidth enhancement of L-probe proximity-fed annular
antenna based on a concentric annular- rings microstrip fed by four apertures is designed. The broadband feed network based on the broadband phase shifter presented in [10] and [11] is used to obtain the required phase shift, thus allowing improvement of the axial ratio in the direction of maximum radiation. This antenna could be

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. 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. 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
This module consists of an annular microstrip line component, two PIN diodes and a DC bias circuit. Reconfigurable circular polarizations can be simply8. Chen, Y.-Y., Y.-C. Jiao, G. Zhao, F. Li, and L.-N. Chen, "Broadband circularly polarized square slot antenna with a novel CPW-FED structure...
