Wideband Dielectric Antennas Exhibiting Circular Polarization

August 31, 2021 -- Norwood, MA -- Artech House today announced the publication of Circularly Polarized Dielectric Resonator Antennas by Raghvendra Kumar Chaudhary, Rajkishor Kumar, and Rakesh Chowdhury. This unique resource introduces wideband circular polarization radiation in dielectric resonator antennas (DRA). It presents five key feeding techniques, including coaxial probe, microstrip, conformal strip, aperture, and coplanar waveguide. It also covers different shapes of dielectric resonator antennas, which will lead to improvement of circularly polarized (CP) performance and explores the advantages and disadvantages of each feeding technique. Important characteristics of DRA, including high radiation efficiency, high gain, wide range of bandwidth, low ohmic losses, high power handling capability, and 3D design flexibility, are discussed.

New techniques that generate broadside circular polarization (CP) by using sectored DRAs in multilayer arrangement are presented. Readers learn how to select appropriate feeding techniques for 5G and Millimeter wave applications in order to generate circular polarization or linear polarization in an electric or magnetic field. Rectangular and circular DRA, with their modified shapes of the dielectric resonator are presented, providing different degrees of freedom as well as different variable parameters such as length, width, height, radius, aspect ratio and dielectric constant, which are tuned to obtain the desired antenna parameters. Written by experts in the field, the book appeals to both novice and experienced engineers.

Circularly Polarized Dielectric Resonator Antennas is available now from Artech House, a leading publisher of books for professionals in high-technology industries.
