Problem

In STAR Antenna Systems, isolation tends to be sensitive to the imbalances in the feeding network and to the asymmetries in the antenna geometry. New configurations that can achieve higher dB of isolation and that can be used across a wide range of frequencies are needed.

Solution

Prof. Dejan Filipovic's team has a new configuration for a Simultaneous Transmit and Receive (STAR) antenna system that consists of a reflector and transmitting and receiving antennas. STAR operation is considered as a key enabling technology for the next-generation wireless networks operating in spectrum congested environments. Transmitting (TX) and receiving (RX) at the same time and over the same frequency channel could potentially result in significant improvements in throughput and spectral efficiency. The proposed antenna configuration achieves high isolation between Transmitter and Receiver without the use of ferromagnetics and aids in achieving high directive beam for the transmitting antenna. This increases the operating range of a communication system and can increase its ability to handle high power, which makes it a potential candidate for electronic warfare (EW) operations. All these features make this configuration a unique candidate for military and civilian STAR applications.

Market Application

Potential applications for this antenna system include Cellular Base Stations, Satellites, Communications Links, Repeaters and RADAR Guidance Systems.
