Description
Thanks to the large bandwidth availability, millimeter and sub-millimeter wave systems are getting more and more attractive to be used in a wide range of applications, such as high-resolution radar or high-speed communications. In this contribution, a wideband H-band (220-320GHz) integrated lens antenna concept fed by a quartz-cavity leaky-wave antenna is presented, to be used in a Frequency-Modulated Continuous Wave (FMCW) radar system. A novel chip interconnect technology, based on spray coating of dielectric materials with low dielectric permittivity, is introduced. This transition acts as a wideband, low loss transition between the GaAs front-end and the quartz antenna, avoiding the use of expensive waveguide split-blocks. Simulation results for the antenna with interconnect show good impedance matching and aperture efficiency higher than 78% over 100GHz of bandwidth. A prototype is currently under fabrication.| Period | 17 Mar 2020 |
