What Makes Log Antennas Effective for EMI Testing

Log antennas achieve 200MHz-18GHz coverage with 10dBi gain, enabling 85% faster EMI scans. Calibrated via three-antenna method (CISPR 16-1-4), their <±2dB ripple maintains ±0.2dB polarization stability, capturing harmonics at 3m distance using 10V/m field uniformity. Broadband Winning Strategies Last month, we resolved the C-band radiation anomaly on AsiaSat 6D—ground stations detected 47dB out-of-band spurious emissions […]

5 factors affecting the bandwidth of circular waveguide

Evanescent modes in waveguides are non-propagating modes that decay exponentially with distance. For instance, in a waveguide with a TE11\text{TE}_{11}TE11​ cutoff at 2 GHz, frequencies below this value (e.g., 1.5 GHz) generate evanescent modes. Mode Cutoff Frequencies for instance, a waveguide with a radius of 4 cm. The cutoff frequency for the TE11\text{TE}_{11}TE11​ mode, the
