Abstract :
In this contribution, an integrated antenna-receiver array is presented. The RF signal is received by open waveguide ports connected to finline mixers. A chain of suspended stripline bandpass filters is used as LO feed network where phase shifting occurs as a function of frequency. Combining the IF signal in a fixed equal-phase network, the antenna array characteristic is scanned varying the LO frequency from -35deg to +35deg while the RF frequency is kept constant. The overall very compact arrangement is integrated on a single substrate and placed in a compact metal mount
