| Summary: | This dissertation discussed the design of 5.8 GHz quasi-Yagi patch antenna for wireless
communications. Most of the researches on the quasi-Yagi antenna designs used a dipole as the
driver element. There are also studies conducted on different driver shapes of the antenna. This
research focused on the use of patches driver in the quasi-Yagi antenna as it is proven to give the
antenna a wider bandwidth and a better radiation pattern which are the needs for the wireless
communication applications. The proposed antenna design is a quasi-Yagi antenna with slotted
microstrip driver operating at a frequency of 5.8 GHz before forming antenna arrays. The etching of
slot on the patch driver is to increase the bandwidth of the antenna, aside from applying antenna
arrays, which also enhances the radiation pattern of the antenna. Printed Circuit Board (PCB),
ROGERS 4003, dielectric material with relative permittivity of 3.38 and thickness of 0.813 mm, is
used in this research. CST Microwave Studio is the simulation tool used to model and simulate the
antenna design before translating the output results to PCB hardware fabrication. The fabricated
antenna is tested using RF equipment to measure the antenna performance parameters and the results
are compared to the simulated results. The conventional quasi-Yagi patch antenna, slotted quasi-
Yagi patch antenna, and slotted quasi-Yagi patch antenna array resulted in a broad bandwidth and a
high gain. The addition of slots and antenna array have enhance the bandwidth of the antenna and
achieve a good radiation pattern. The proposed antenna and its array is suitable for SHF band
applications and wireless communication system. |
