Dielectric Resonator Antennas Materials, Designs and Applications

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.
