A low-cost and very small wireless terminal integrated on the back of a flat panel array for 26 GHz band fixed wireless access systems
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 FWA (fixed wireless access) system in 26 GHz frequency band. Drastic cost reduction and downsizing are realized by using an alternating phase fed single layer waveguide array antenna and MMIC (microwave monolithic IC) 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 radome, RF module, IF modules, ASIC (application specific IC) for modem, TDMA (time division multiple access) equipment control, and MAC (medium. access control). Only an Ethernet cable with 24 DC power supply is attached on the terminal. This paper describes the design of WT with the focus upon the unique antenna and RF module.
