A Micromachined 94 GHz Dielectric Resonator Antenna for Focal Plane Array Applications
Paper in proceeding, 2007
In this paper a new concept of integrating micromachined high-resistivity (HR) silicon dielectric resonator antennas (DRAs) compatible with a millimeter wave multichip module deposited (MCM-D) process based on multiple layers of BenzoCycloButhene (BCB) is presented. The HR Si wafer is used not only as a carrier substrate for the BCB but also for manufacturing of the integrated antenna elements. A 4×8 focal plane array (FPA) was designed for use in a 94 GHz imaging radar system. Each channel uses a small 2×2 DRA subarray as feed element. By using the presented antenna a higher impedance bandwidth and radiation efficiency can be attained compared to the use of microstrip antennas. An improved isolation between the antennas and the feed lines/active circuits is also realized. © 2007 IEEE.
