Abstract :
A new integrated millimeterwave patch antenna HEMT receiver for imaging applications is presented. The mixer element is a HEMT working in a resistive mode. We use a relatively thick layer of BenzoCycloButhene (BCB) as dielectric support for the antenna element, and to realize microstrip based circuits. At an RF of 35 GHz we obtain a minimum conversion loss of 8 dB, defined as the IF power dissipated in a 50 /spl Omega/ load divided by the available power from the patch antenna.<>
