Abstract:
A distributed antenna device comprising:a plurality of transmit antenna elements; a plurality of receive antenna elements; and a plurality of power amplifiers, a power amplifier being operatively coupled with each of said transmit antenna elements and mounted closely adjacent to the associated transmit antenna element, such that no appreciable power loss occurs between the power amplifier and the associated antenna element; at least one low noise amplifier for receiving and amplifying signals from at least one of said receive antenna elements; each said power amplifier comprising a relatively low power, relatively low cost per watt linear power amplifier; said device being configured such that said transmit antenna elements and said power amplifiers coupled thereto, and said receive antenna elements and said at least one low noise amplifier coupled thereto are continuously active and capable of simultaneous respective transmit and receive operations; wherein said receive antenna elements are in a first linear array and said transmit antenna elements are in a second linear array spaced apart from and parallel to said first linear array; and further including an electrically conductive center strip element positioned between the first and second linear arrays.
