Problems solved by technology

However, duplexers are large, expensive and introduce signal loss
Other solutions can use circulators, which are also bulky and expensive
Therefore, conventional solutions using duplexers and / or circulators are undesirable on vehicles, such as aircraft, where space and weight constraints are important design parameters

Abstract

An antenna system is provided. The antenna system includes a planar array of antenna elements configured to operate as an array having a plurality of receive (Rx) antenna elements for receiving a signal in a first frequency band and a plurality of transmit (Tx) antenna elements for transmitting a signal in a second frequency band. The Rx antenna elements and the Tx antenna elements are interleaved in a pattern such that total Tx power leakage is distributed among the plurality of Rx antenna elements. Furthermore, each Rx antenna element is provided with a high dynamic range amplifier (HDRA) for amplifying a receive signal and filtering any Tx power leakage at each Rx antenna element.

Description

technical field [0001] The present disclosure relates to antennas for satellite communications, and more particularly to antenna assemblies including arrays of antenna elements configured to operate as an array. Background technique [0002] Antenna arrays may be used on vehicles, especially aircraft, for receiving signals from and transmitting signals to other sources such as satellites. Conventional antenna systems typically use diplexers to isolate received and transmitted signals having different frequencies. However, duplexers are large in size, expensive and introduce signal loss. Other solutions could use circulators, which are also bulky and expensive. Therefore, conventional solutions using duplexers and / or circulators are undesirable on vehicles, such as aircraft, where space and weight constraints are important design parameters. Efficient antenna systems that can be easily used on vehicles in general and aircraft in particular are currently being worked on. ...
