碩士 === 國立交通大學 === 電信工程研究所 === 101 === In this thesis, 3 different kinds of antennas for 24GHz radar systems are proposed, of which the operation band is from 24.05 GHz to 24.25 GHz. The first design is for blind spot detection radars due to its highly integration and low-profile structure. The second type of antenna is fabricated in a 2-layer structure, which is low profile, low cost and easy integration. Two out-of-phase vias are used as the antenna feed, hence increases the bandwidth of the radiation pattern. Therefore, it can be used in short range detection radars. In the last design, a balanced feed is used in order to improve the impedance bandwidth. With high gain, narrow-beamwidth, and low-sidelobe-level, this antenna is used in long-range-radar applications.
