Abstract:

A method and apparatus for a multiband frequency distributed circuit apparatus with FSS. The apparatus includes a circuit, a first dielectric layer, a first FSS layer, a second layer and a ground plane. The first dielectric layer is operatively coupled to the circuit. The first FSS layer is operatively coupled to the first dielectric layer and is capable of passing a first frequency band. The second layer is operatively coupled to the first FSS layer and includes a dielectric material. The ground plane is operatively coupled to the second layer. A method for implementing a multiband frequency distributed circuit is also disclosed.

International Classification:

H04M 1/00

US Classification:

4555531, 455296, 455 6713

Abstract:

A frequency agile collocated multi-signal rf distribution system. The system includes a plurality of receivers, a plurality of transmitters, a power amplification module, an antenna module and an interference reduction module. The power amplification module is operatively coupled to the plurality of transmitters and is capable of receiving and amplifying transmission signals, reducing interference and outputting amplified transmission signals. The antenna module is operatively coupled to the power amplification module and is capable of receiving amplified transmission signals, receiving reception signals and outputting reception signals. The interference reduction module is operatively coupled to the power amplification module, the antenna module and the plurality of receivers, and is capable of receiving amplified transmission signals and reception signals, reducing co-site interference in receptions signals, and outputting reception signals having reduced co-site interference to the plurality of receivers. A method for implementing a frequency agile collocated multi-signal rf distribution system is also described.
