Today, more and more antenna engineers are viewing the Dielectric Resonator Antenna (DRA) as a preferable alternative to conventional low-gain designs because of several attractive features, including high radiation, light weight, small size and low profile. This practical resource presents complete, up-to-date details on DRAs in a single volume. The book provides professionals with clear guidance on the mode of operation and radiation behavior of DRAs, the main methods of excitation, and the major advances in DRA technology. This hands-on reference equips engineers with simple equations and graphs that help them rapidly design DRAs, without the need for complex analytical or numerical calculations. Numerous design examples are included to give practitioners a sense of the versatility that DRAs afford.

The use of dielectric resonator as a resonant antenna was proposed in 1983. Due to the absence of metallic loss, the dielectric resonator antenna (DRA) is highly efficient when operated at millimetre wave frequencies. With the use of high dielectric constant material, the DRA can also be used as a small and low profile antenna operated at low microwave frequencies. Low cost dielectric materials are now easily available commercially, encouraging more antenna engineers to design communication systems with DRAs.

Dielectric Resonator Antennas A detailed guide to dielectric-based techniques for antenna array design and construction Dielectric designs, which transmit electricity without conducting it, have in recent decades been increasingly incorporated into antenna arrays. The resulting Dielectric Resonator Antennas (DRAs) provide significant benefits over metal antennas, avoiding conduction loss and increasing efficiency. Dielectric elements can also be incorporated into metal antennas to improve performance. Dielectric Resonator Antennas provides an introduction to dielectric-based techniques for manufacturing antenna arrays. It supplies guidelines for identifying dielectric antenna designs (as opposed to metal ones), describes recent developments in dielectric antenna technology, and points toward potential areas of future growth and development. Readers will also find: Cutting-edge DRA applications in microwave and millimeter-wave communications Detailed discussion of array types including wideband, high-gain, high efficiency, and more Instructions for fabricating dielectric antenna arrays and assessing tolerance levels Dielectric Resonator Antennas is ideal for researchers and students in electrical engineering, as well as for engineers and others working in wireless communications.

Abstract: A linear array of rectangular dielectric resonator antenna (DRA) is studied. The array is excited by a dielectric image guide. The advantages of using the dielectric image guide (DIG) are the low losses at high frequencies, and wideband performance. Two different methods of coupling between the dielectric resonator elements and the image guide are investigated. The first method of coupling is to couple the image guide to narrow apertures (slots) that are in turn exciting the dielectric resonator elements. Two problems are found in this design. First, this design causes high return losses around the slot resonances. This problem is resolved by adding a reflection cancelling slot near each main slot. The second problem is the high back radiation. This problem is resolved also by using a conducting reflector on the DIG feeding side of the antenna. The second method of excitation is the proximity coupling method between the dielectric resonator antennas and the DIG. Coupling analysis and design of single element and two different arrays are performed. It is found that this design achieve low back radiation, but high cross polarization. The cross polarization is reduced by suppressing some high order modes that are excited in the DRA elements. This suppression of these modes is performed by wrapping the middle of each DRA by a conducting strip. The coupling between the DRA and the DIG is controlled by the separation distance between them. A Dolph-Chebyshev amplitude distribution is used to control the sidelobe level of the far field radiation patterns. A prototype was build for each design from a 7-element array. The measured and computed results are in good agreement. Two 15-elemet arrays are studied numerically and show that to improve the antenna efficiency, and a reasonable number of elements must be used to couple most of the input power to the radiating elements.
