A Wideband Antenna Calibration Network Using Multi-Layer Coupling Technology

In this paper, the realization of foundation of a wideband calibration network is presented. The network framework includes division layer, coupling layer and transmission layer. To establish the feasibility, a calibration network is processed and stress-tested for reliability. The evaluation results indicate that in the 8-16GHz range, the amplitude fluctuations of the coupling degree are ±3.5dB or less and phase deviations are ±4° or less, while also exhibiting high isolation and good matching performance.
