Compact and lightweight, the R&S ADD507 direction finding (DF) antenna covers 9 MHz to 8 GHz, reducing the need for multiple antennas.

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 ...

Figure 5. Near to far field transformation for the case of a simple half-wave dipole antenna. The top row shows the Poynting flux in the simulation domain’s X-Y, X-Z and Y-Z planes. The bottom row ...

The experimental results indicate that the array antennas integrated with the proposed converter can achieve an overlapped impedance and axial ratio (AR) bandwidths of 11.1% (8.18-9.14 GHz) and 13.6% ...

Abstract: This paper investigates the leakage radiation phenomenon between adjacent sinusoidal impedance surfaces ... method is applied to control leakage values along the antenna, enabling precise ...
