Abstract :
With the development and improvement of society, the implement of communication equipment becomes more and more widespread. Due to compact structure, beautiful appearance, and small volume weight, microstrip antenna is adopted far and widely. However, microstrip antenna has defects of low gain and narrow bandwidth, so the fractal technology is adopted to improve microstrip antenna, and make it better application in this paper. Active receiving antenna is a component which associates an active component with a passive radiating element. On the one hand, it can cover more flexible and changeable networks, on the other hand, it will eliminate the losses which is caused by radio frequency cable and the decline of link quality. There are many kinds of active antennas, which contain the active antenna amplifier circuit. The design in this paper makes use of 2st iteration of Minkowski fractal microstrip antenna to reduce the size of the antenna. Then, it utilizes the chip of truiqunt9035 to achieve a low-noise amplifier. At last, it finishes the design of miniaturized broadband minkowski active microstrip antenna by linking the antenna to the low-noise amplifier.
