A novel compact coupled planar resonator (CCPR) based VCO (voltage controlled oscillator) using mode-coupling technique was developed in response to expensive high Ceramic and SAW resonators based signal source for wireless communications. One of the problems related to the conventional Ceramic/SAW based resonators (with high Q and low phase noise) is the challenge for integration in IC form. Instead...
Microstrip Antennas (MSAs) consist of a metallic radiating patch on one side of thin dielectric substrate and other side is ground plane. Most important advantages of MSAs are low profile, light weight and compatibility with integrated circuit technology. MSAs are used in mobile communication, satellite communication, radar, direct broadcasting, global positioning systems and remote sensing. The major...
We derived an equivalent circuit for a figure-8 coil type permeance meter in order to analyze its LC resonance characteristics. The equivalent circuit for the pickup coils was derived by using the same analytical techniques as for thin-film inductors. The driving sheets and twisted lead wires were modeled according to the theory of distributed constant networks. We made a permeance meter, measured...
