Abstract: Aiming at the problems of low gain, low efficiency in low frequency band and warping pattern in high frequency band of the existing HF broadband whip antenna, this paper introduces frequency ...

Designed and manufactured in the U.S., these antennas deliver exceptional radio frequency (RF) performance from L-band (1.35 GHz to 2.5 GHz) to S/C-band (2.2 GHz to 2.5 GHz and 4.4 GHz to 4.49 GHz).

Engineers combine measured data, multi-level behavioral models, and simulation tools to predict real-world performance across ...

Air Traffic Controllers use Automatic Dependent Surveillance-Broadcast (ADS-B) as an alternative to secondary radar to track aircraft. The ADS-B is transmitted by the aircraft and contains information ...

Abstract: High-frequency (HF) ground-wave radars employing compact antenna arrays are advantageous in practical applications because of their convenient deployment. However, the direction-of-arrival ...
