In order to achieve high compactness and high performance for next generation wireless networks, this thesis investigates the use of a material with a high dielectric constant (approximately 20) and low loss for integrated design of microwave filters and antennas. Two different filtering antenna designs in the 3.5 – 3.7 GHz frequency range are presented. A dual-mode waveguide filter is used in both designs, while a microstrip antenna is used for one design and a dielectric resonator antenna (DRA) is used for the other. Microstrip antenna and DRA are used due to their low-profile, ease of fabrication and light weight. The integrated designs are validated using full wave electromagnetic (EM) simulations, showing comparable performances. Both designs are compact, low loss, and have dual-polarization with good isolation, making them ideal for 5G mobile communication applications.enFilter antenna integrationDual-polarizationDielectric resonator antennasMicrostrip antennasThesis
