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. Printed ring slot antenna for circular polarization - IEEE 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.

DESIGN OF CPW-FED DUAL-BAND CIRCULARLY- POLARIZED ANNULAR ... Abstract|A new CPW-fed dual-band circularly-polarized(CP) annular slot antenna with two perturbation strips is proposed. The structure of the annular slot, along with two concentric annular-ring patches, can achieve dual-band input impedance matching. And circular polarization at the operation bands can be achieved by using A single-feed tri-band circularly polarized dual-annular ... A novel single-feed tri-band circularly polarized (CP) dual-annular slot antenna is presented. The antenna structure is composed of two nonconcentric annular slots fed by a novel inverted h-shaped microstrip line conﬁguration. Compared to most of the previously reported tri-band CP antenna structures, the proposed antenna has low proﬁle ...
