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 ...

SAN ANTONIO -- Nov. 19, 2019 -- Mitigating ongoing threats to national security requires timely intelligence data, including signals intelligence (SIGINT) obtained through electronic surveillance.

I’m going to go out on a limb here and start with a statement: In the real world, there is no such thing as a non-directional FM broadcast antenna. An isotropic radiator may be theoretically possible, ...

The use of directional arrays in FM broadcasting has increased greatly in 30 years. Especially in the NCE reserved band, a DA can increase the operating power of a station significantly while still ...

We have been able to conclude that using an isotropic antenna, an RFID reader might achieve a read range of a few meters with 1 watt of output power. This configuration might be fine if RFID tags of ...
