The main feature of the phased-array microsystem is the high integration of circuit and antenna, which closely combines the three-dimensional micro-nano integration and the microelectronics technology to meet the development needs of high frequency, miniaturization and low cost of the phased array. Phased-array micro-system with a packaged antenna operating in the W-band is designed and introduced in this article. The phased array integrates multi-functional chips and antenna together in a microsystem by means of silicon-based three-dimensional integration. The design of the multi-functional transceiver chip and the phased-array packaged-antenna are analyzed. The test results of the phased array microsystem are also provided. The microsystem exhibits the characteristics of high integration, high performance and low cost, paving a technically advantageous path for high data-rate wireless communication, high-precision detection, imaging and other applications.
