碩士 === 國立交通大學 === 電資學院學程碩士班 === 89 === In this thesis the main idea is the design of millimeter wave (28 GHz) microstrip antenna with various feeding configurations, in order to be applicable in all transceiver systems. The feeding configurations include microstrip line-fed, coaxial line-fed, and rectangular waveguide-fed configurations …etc. With the microstrip line-fed and coaxial line-fed structures individually, we also complete one 8 X 1 series-fed microstrip antenna array, which is used in a 28 GHz video relay system. Operating in millimeter wave frequency range, the discontinuities in the circuit result in serious circuit parasitic effects, so we must design and simulate with a full wave EM software (HFSS). Also, due to the short wavelength and delicate fabrication, a good analysis and design technique is necessary to achieve the desired performance. The measured results of return loss and radiation pattern simultaneously show good agreements with the single patch antenna and antenna array design.
