Compact amplifier integrated microstrip antenna

Abstract

A compact microstrip antenna integrated with an amplifier having an area reduction of 70%, compared to the standard circular microstrip patch antenna, is presented. The antenna also provides an enhanced gain of 10‐dB more than its passive counter part. The measured 2:1 VSWR band width is ∼4% at 790 MHz, which is 2.5 times larger than that of the passive microstrip antenna. © 2004 Wiley Periodicals, Inc.

Co-Design of a GPS Antenna Low-Noise Amplifier Front-End Circuit

“…Several prototypes have shown that significant improvements of performance and integrability can be achieved when co-designed antenna-amplifiers are used [6]- [9]. A clear example is shown in [8] where a smaller footprint area was achieved by using a low noise amplifier (LNA) directly matched to the microstrip antenna. Likewise, a microstrip antenna reported in [9] was co-designed in order to meet a given gain matching condition.…”

Design of penta‐band antenna with integrated LNA circuit for vehicular communications

“…It can be integrated with passive antenna either at its input port or at its output port, which depends on transmitter or receiver. In receiver part, passive antenna and LNAs are integrated to reduce the system's noise performance [7][8][9][10][11][12].…”
