Abstract

In this paper an active antenna, including a compact high-efficient class E amplifier and a microstrip antenna working at 2.45 GHz is investigated for microwave front-end transmitter applications. At first, a probe fed microstrip antenna with an arc shaped slot is used to suppress the second harmonic. The probe position is aligned to obtain a 50  matched load, and hence the matching network is eliminated. A high efficient class E amplifier is also designed and investigated. Both structures are placed on a same PC-board of Rogers RT Duroid 5870. They are numerically investigated using Advance Design System (ADS). The results show that the Power Added Efficiency (PAE) is at least 71% at the frequency of 2.4 GHz. Also, the second and third harmonics of the amplifier are significantly suppressed at the output of the antenna.
