Performance Analysis of Dielectric Resonator Antennas
Compact, lightweight and low cost electronics components are attracting much attention because of the rapid growth of the wireless communication systems. The antenna designers are thus in continuous search for new advanced design of miniaturized antennas. One solution is to use a dielectric resonator antenna (DRA) which provides various benefits in terms of the performance. This paper presents fundamental concepts, theory and review study carried out on DRAs. The achievable performance of DRAs designed for wide impedance bandwidth, low profiles, circular polarization, compactness, and high gain are illustrated. The latest techniques for improving the results are also covered.
