Abstract

In this paper, an active antenna for terrestrial DMB(Digital Multimedia Broadcasting) repeater is designed. This active antenna is consist of receiving antenna and LNA(Low Noise Amplifier), A receiving antenna fed by using a microstrip line and radiation part is designed with rectangular spiral structure. An receiving antenna with frequency range of 162$\sim$212MHz, gain of -10dBi and LNA with gain of 20dBi, noise figure of 2.2 at frequency range for T-DMB are achieved.
