In this contribution, a simple but highly sensitive biosensor based on microstrip ring-resonator is presented for tissues moisture evaluation. By incorporating high impedance ring, tight and enhanced coupling mechanism the proposed 1 GHz ring-resonator demonstrates significant change in the resonance frequency than normal resonator. Simulated and measured results are in good agreement. The proposed...
In high-speed printed circuit board (PCB) designs, vias play a critical role in determining signal and power integrity. This paper uses disk resonators to investigate modeling approaches for common via array structures. Boundary integral equation (BIE) and effective dielectric medium approaches are used for a perforated disk resonator with non-plated holes, using dielectric properties derived from...
