KWRM(AM) is using an innovative antenna design to serve southern California. Consultant Lowell Homburger says there's no ...

The sky is awash with radio-frequency interference (RFI), but thanks to two astronomers who tracked down a stray TV broadcast reflected off a passing airplane, there may be a new way to wipe out some ...

It will provide this service over Europe, Africa and the Americas. "Something as complex as the DRAs antennas in X-Band, an active antenna that can move the beam electronically and can configure ...

Abstract: This paper describes a new method for synthesis of a flat-top beam radiation pattern of three-element antenna arrays. Currently, this is the only method that: (1) gives a semi-analytical ...

Abstract: This work proposes an electrically tunable reconfigurable antenna array with wideband radiation and scattering modulation using a simpler structure and an easier control mechanism. A ...
