碩士 === 大葉大學 === 電信工程學系碩士班 === 93 === ABSTRACT
In this paper, an amplifier active antenna to be operated in 930MHz for the pager . This active antenna consists of an active element and a passive element . The active element is a low noise amplifier and passive element is a loop antenna.
First, we design a loop antenna which is operated in 930MHz , measure pattern and antenna gain .Next, we design a low noise amplifier, measure noise figure、isolation and gain. Finally, by combine the two and fabricate the active antenna , measure pattern、antenna gain and average gain .
The active antenna gain is 3.5dBi, active antenna average gain is 0.6dBi, such performance is suitable for the pager receive.
