Abstract

This work presents the design of an active amplifier antenna. Active integrated antennas can be obtained with active components directly connected to the antenna structure. In this article, a novel active integrated single microstrip antenna analysis and its radiation pattern and gain performance is proposed. A high‐efficiency, low noise, and high linear compact amplifier integrated with a microstrip antenna at 1.6 GHz is presented for RF front‐end circuit applications. The design in this study consists of a rectangular microstrip antenna with a pair of parallel slots loaded close to the radiating edge of the patch and three meandering narrow slots embedded in the antenna surface. With the proposed design a size reduction of 34% for the 1.6‐ and 2.6‐GHz resonant frequencies is obtained and the two frequencies have an operation frequency ratio of 1.30. In this design approach, the measured antenna impedance is transformed with matching to the load impedance for maximum efficiency. With the proposed amplifier antenna design, the antenna radiation pattern can be better than an antenna radiation pattern without matching. In addition, it has been shown that compensation significantly improves the return loss matching level. © 2008 Wiley Periodicals, Inc.
