Circularly Polarized Wideband-to-Narrowband Switchable Antenna

Wideband Single-Feed Circularly Polarized Antenna

In this paper, a novel wideband single-feed circularly polarized patch antenna is presented. The antenna consists of an L-shaped probe, four parasitic patches perpendicular to the probe, and a planar reflector. By modifying the structure of the patches, two orthogonal radiation modes are created to realize the circular polarization in the broadside direction. This antenna exhibits a wide impeda...

Wideband Circularly Polarized Microstrip Patch Antenna for Wireless LAN Applications

A small wideband microstrip patch antenna is introduced. The antenna is designed to function in the 5-6 GHz wireless LAN bands. It achieves multi-band functionality through the addition of a slot to a square patch (21 mm by 21 mm by 2.6 mm). The proposed antenna also generates circular polarization and has a 3 dB axial ratio bandwidth of 2.8%. The impedance bandwidth of the antenna is more than...

Novel Ultra Wideband Circularly Polarized Rectangular Patch Antenna

In this paper a very simple micro-strip rectangular patch antenna is proposed with circular polarization and enhanced bandwidth for mobile Ad Hoc network. By using the orthogonal feed orthogonal linear components has been produced having phase difference of odd multiple of 90 ̊. For enhancing the bandwidth the rectangular patch has been truncated. The bandwidth of antenna is 12%. The proposed an...

A Wideband Circularly Polarized Pixelated Dielectric Resonator Antenna

The design of a wideband circularly polarized pixelated dielectric resonator antenna using a real-coded genetic algorithm (GA) is presented for far-field wireless power transfer applications. The antenna consists of a dielectric resonator (DR) which is discretized into 8 × 8 grid DR bars. The real-coded GA is utilized to estimate the optimal heights of the 64 DR bars to realize circular polariz...
