Rectangular Dielectric Resonator Antenna Thesis

On the other hand, dielectric resonator antennas (DRAs) are promising candidates to replace traditional radiating elements at high frequencies, especially for applications at millimeter waves and beyond.

This is mainly attributed to the fact that DRAs do not suffer from conduction losses and are characterized by high radiation efficiency when excited properly.

These antennas are characterized by small size, low weight, and low cost and can be easily integrated on chip.

However, unless advanced design solutions based on the integration of suitable dielectric superstrates or lensing structures are adopted, these antennas typically suffer from reduced radiation efficiency and narrow impedance bandwidth due to the effect of lossy silicon substrate materials.

By using a suitable excitation technique, any dielectric structure can become a radiator at defined frequencies.

It is to be noticed that, for a given resonant frequency, the size of the dielectric resonator is inversely proportional to the relative permittivity of the constitutive material.The main target of this paper is to present an up-to-date review study summarizing the most relevant techniques to control circuital characteristics and radiation properties of DRAs.In this way, guidance will be provided to RF front-end designers to achieve the required antenna performance in terms of gain, bandwidth, and polarization.DRAs rely on radiating resonators that can transform guided waves into unguided waves (RF signals).In the past, these antennas have been mainly realized by making use of ceramic materials characterized by high permittivity and high Due to the absence of conducting material, the DRAs are characterized by high radiation efficiency when a low-loss dielectric material is chosen.Furthermore, different techniques to achieve circular polarization are summarized.Finally, the most recent implementation of DRAs on chip and off chip will be presented.These are the elliptical DRA, the DRA with a rectangular slot, the adjustable reactance feed, the triangular DRA and the dual band DRA-patch antenna.

The lowest dielectric constant material adopted in DRA design is reported in [2–4], where commodity plastics with relative dielectric constant smaller than 3 have been utilized for the realization of supershaped DRAs.The basic principle of operation of dielectric resonators is similar to that of the cavity resonators [5] and is thoroughly discussed in literature.
