Abstract
A distributed antenna array includes a plurality of antenna elements and a plurality of power amplifiers, each power amplifier being operatively coupled with one of the antenna elements and mounted closely adjacent to the associated antenna element, such that no appreciable power loss occurs between the power amplifier and the associated antenna element. Each power amplifier is a relatively low power, relatively low cost per watt linear power amplifier chip. The antenna array may be used in various installations, including cellular, PCS, MMDS, LMDS and in-building communication systems such as LANS or WLANS.
