无线IP接入系统（WIPAS）是一种26 GHz频段的点对多点固定无线接入（FWA）系统，设计了一种高增益平面阵列的小型无线终端（WT）。对于农村地区的点到多点FWA业务，具有高增益天线和RF模块的WT的成本和尺寸的大幅减小是不可或缺的。本文采用微波单片集成电路（MMIC）技术，采用交替相位馈电的单层波导阵列天线，实现了1/10的成本降低和1/5的尺寸缩小。该终端的体积为190/spl times/190/spl times/55 mm/sup 3/，重量小于2.0 kg，可容纳31 dBi以上的极高效天线，该天线具有天线罩、RF模块、IF模块、用于调制解调器的专用IC（ASIC）、时分多址（TDMA）设备控制和媒体访问控制（MAC）。终端上只连接一根24 V直流电源的以太网电缆。
A compact wireless terminal (WT) with a high-gain planar array has been developed for the Wireless IP Access System (WIPAS), which is a point-to-multipoint Fixed Wireless Access (FWA) system in the 26 GHz band. For the point-to-multipoint FWA services in rural areas, the drastic cost and size reduction of WT with the high-gain antennas and RF module is indispensable. In this paper, remarkable cost reduction of 1/10 and downsizing of 1/5 are realized by using an alternating phase fed single layer waveguide array antenna and Microwave Monolithic IC (MMIC) technologies. This terminal is 190/spl times/190/spl times/55 mm/sup 3/ in volume and less than 2.0 kg in weight which accommodates over 31 dBi very high efficiency antenna with a radome, RF module, IF modules, application specific IC (ASIC) for modem, time division multiple access (TDMA) equipment control, and medium access control (MAC). Only an Ethernet cable with 24 V dc power supply is attached on the terminal.
