碩士 === 國立中央大學 === 電機工程研究所 === 99 === This paper is presented a V-band tapered slot antenna array applied to high-bit-rate wireless transmission system. With more requests for wireless video transmission and entertainment, and the 60 GHz carrier frequency is available to be an unlicensed band, so the applications around 60 GHz interest more people to research. However, in this band the propagation loss is about 20 dB higher than that at 6 GHz. Therefore, the system needs high gain and high directivity antennas to compensate these effects. Tapered slot antennas have high gain and high directivity, and its structure is suitable as radiating elements for arrays of brick architecture so that the antenna gain increases. In this paper, the geometric parameters of tapered slot antennas are analyzed to get better gain and radiation status. The feeding technique uses a lumped-element coplanar waveguide to slotline transition which includes the L-section matching network; it can reduce the area of feeding circuits for power-combining block of array. the antenna array is composed of N antennas which are arranged in rows connected horizontally to be a 1×N tapered slot antenna array. The V-band tapered slot antenna array is realized with GIPD (integrated passive device on glass substrate) process to improve the low gain of general chip antennas. The characteristics of antenna array will be measured, including return loss, gain and radiation pattern, to verify the operating efficiency.
