Abstract :
This paper presents results for a novel two element active transmit-receive array using dual linear polarisation and sequential rotation. Each element includes an integrated (MESFET) oscillator and amplifier mounted on orthogonal edges of a square patch, such that transmit and receive paths are isolated and polarisation duplexed. The array gives in excess of 55 dB transmit-receive isolation at 3.77 GHz.
