Today, the demand for wireless communications is growing faster than ever, as RF/microwave technology has undoubtedly become a part of our daily lives. In wireless communications, the antenna plays a very important role because it directly affects transmission and reception. Recently, the dielectric resonator antenna (DRA) has been studied extensively because of its inherent merits of low loss, small size, low cost, and ease of excitation.Multifunction has been used extensively in the RF/Microwave system for reasons of size and cost reduction. In this project, the DRA will provide additional functions to reduce the system size and lower the cost. The project will be divided into two parts. In the first part, the DRA will also serve as the oscillator load, called the DR antenna-oscillator (DRAO). The second part of the project will utilize the DRA as the filter element, and the configuration will be called the DR antenna-filter (DRAF). For the DRAF, multiple DRs will also be used to improve the filter performance and antenna gain. The problems will be theoretically modelled, along with comprehensive measurements. Design curves will be generated, and the results will facilitate engineers to design the DRAO and DRAF easily and quickly.
