A broadband (10–20 GHz) lightweight receive module on multilayer LCP technology for radar applications

A broad-band single substrate module receiver is built on multi-layer flexible substrate. The module consists of a Vivaldi antenna array, power combiner, and multilayer filter. The measured antenna array (2 × 1) shows high gain over a wide frequency range. The filter is designed for bandpass characteristics over a 0.75 GHz bandwidth. Low-cost, light-weight compact modules can be designed using the proposed process using multilayer LCP.
