High Power Transmit/Receive Antenna for Airborne Applications

SBIR Phase II proposal is submitted here for evaluation. A compact millimeter-wave waveguide-integrated low loss antenna with a forward tilted fan-beam covering about 90x3.2 degreesis proposed. A total of eight antennas will be integrated into a 4-inchdiameter package. The package also will include at least two sets of oscillator-upconverter modules and four receiver mixers to generate four sets of ultra-linear FMCW waveform radar sensors as our basic approach to the Smart Sensor Package (SSP). Asemiconductor monolithic integrated frontend approach will also be investigated to take advantage of the ongoing development of millimeter-wave communication and radar frontend chip sets in the market place. Electronics will be supplied by CHANG for thethe test and evaluation of the integrated sensor frontend package. The test electronics supplied by us will emphasis the ability for future electronics (including digital signal processor) miniaturization and integration into the 4-inch diameter package.
