In this work, measurement of the single-molecule magnet (SMM) spin state using a microstrip resonator is considered theoretically. An analysis of the SMM spin dynamics and the interaction between the microstrip and the SMM is presented. The interaction of the SMM with the microstrip causes a shift of the microstrip resonance frequency. An analytic expression for the maximum frequency shift is d...

Another important observation is made for multiple split ring reso...

Microstrip patch antennas are well known for their advantages in terms of small weight, low profile and ease of manufacture. However, the main limiting factor in implementing these antennas in many applications is their low impedance bandwidth (typically 2-3%). One popularly used technique of enhancing the bandwidth is to use multi-layered microstrip[1,2]. The most widely accepted structure in ...

The sensor is implemented using planar microstrip technology. A dielectric material is placed above microstrip ring resonator. As a consequence the near field of the resonator interacts with the material un...

Compact selective bandpass filter, based on the Rhodes approximation, is proposed using the novel modified hairpin resonators realized on a double-sided microstrip. The equivalence is presented between the hairpin resonator realized on a singlesided microstrip and the modified hairpin resonator realized on a double-sided microstrip. The footprint area of the filter is reduced by 50% with the mu...
