Abstract :
The resonant behaviour of a novel microstrip rhombic resonator is investigated by analysing an equivalent circuit based on transmission line modelling. Design curves showing the dependence of resonator performance on its parameters, as well as the substrate parameters, are presented. Experiments carried out showed a significant reduction in insertion loss when the rhombic resonator is dielectrically shielded. The resonator could be use as a microwave bandpass filter or a stabilisation circuit for microwave oscillators in both hybrid and monolithic integrated circuits.
