Abstract

After the release by the Federal Communications Commission of frequency range from 3.10 GHz to 10.6 GHz in 2002 for Ultra-wideband (UWB) wireless communication applications, UWB technology has become a hot research field. One of the challenges is designing an antenna of smaller size for wider frequency range applications. The objective of this thesis is to design UWB antennas for future 5G that able to operate from frequency range 2.0 to 12 GHz. Microstrip patch antenna design is chosen for designing UWB antenna due to its low budget and can be fabricate easily. In this thesis, microstrip patch antennas are designed for two different shapes of patch by using flame retardant 4 (FR4) as substrate. Techniques such as etching slots and defected ground structure is presented for both antennas and effect on both antennas is compared and discussed. The design of the UWB antenna is conducted via a simulation with CST Studio Suite 2019 software. The parameters of the antenna such as return loss, gain, radiation pattern and Voltage Standing Wave Ratio have been investigated.
