Modern wireless communications has evolved greatly within the past 30 years, and antennas are a significant part of the today's society. Almost everyone has a smartphone equipped with multiple antennas, and antennas are found in many everyday household objects and devices such as washing machines, coffee makers, and robotic vacuum cleaners. Furthermore, wearable antennas (such as those in medical devices, clothes, and watches) are becoming increasingly popular. In summary, antennas are placed in unconventional locations demanding new antenna design methods. Multiport antennas may provide benefits as compared to traditional single-port antennas. Therefore, this thesis discusses novel design methods for multiport antennas which requires new d...
