Abstract

Monolithic Microwave Integrated Circuits (MMICs) and Microstrip Antennas (MSA) technologies are used in the design and development of a cylindrically shaped conformal array system as presented in Kanno er al (1)(4)(6) operating at X-band to be used for mobile communications, as well as remote sensing - radar applications. A novel hybrid Method of Moments and Method of Auxiliary Sources technique is employed to design the printed antenna array on the curved surfaces. MMICs are designed for the QPSK modulator/demodulator using the F20 GaAs foundry process of GEC-Marconi as described in (15) in the framework of the EUROPRACTICE Action. Low noise and power amplifier as well as the diplexer filters and the circulator have been designed based on MIC technology on TEFLON R4003 substrates. An IF band signal processing is employed for phase shifting of the array elements, without using amplitude control at the first stage.
