Reconfigurable Rectangular Dielectric Resonator Antenna for X-band and Millimetre-Wave Applications

Reconfigurable antennas are in high demand for use in modern wireless communication systems, since their frequency, polarisation, and pattern, can be dynamically changed. Recently, dielectric resonator antennas (DRAs) have been extensively studied owing to their high efficiency, low cost, ease of excitation, and high degree of design flexibility. Additionally, various types of reconfiguration techniques have been identified and thoroughly investigated to meet the ever-increasing demand for new and advanced technologies. This research explores the feasibility of designing reconfigurable DRAs with various types of reconfigurability directions, particularly in response to the growing interest in the field of DRAs over the past thirty years.
