Patent ID: 6900775

Claim:
An antenna array arrangement for a wireless communication network, comprising: a plurality of transmit active antenna elements, each active antenna element including: a transmit amplifier; a bandpass filter receiving a signal from the transmit amplifier; an antenna structure constructed and arranged to radiate an electromagnetic wave corresponding to a signal from the bandpass filter; and a plurality of receive active antenna elements, each including: an antenna element constructed and arranged for receiving signals, a receive bandpass filter arranged to receive signals from the antenna element, and a receive amplifier for amplifying signals from the filter. wherein said transmit active antenna elements and receive antenna elements are disposed in a repeating alternating configuration such that each of said transmit active antenna elements are separated from each other by an optimal distance enabling said transmit active antenna elements to form a relatively narrow transmit beam by combined radiation of at least consecutive ones of said transmit active antenna elements, said beam being steerable by phase control of consecutive ones of said transmit active antenna elements and each of said receive active antenna elements are separated from each other by said optimal distance enabling said receive active antenna elements to form a relatively narrow receive beam by combined radiation of at least consecutive ones of said receive active antenna elements, said beam being steerable by phase control of consecutive ones of said receive active antenna elements, and wherein said transmit active antenna elements are controllable to form a transmit phased array and said receive active antenna elements are controllable to form a receive phased array.
