Compact Dual-mode, Dual-band, Microstrip Filter with Multiple Transmission Zeros

A compact microstrip, dual-mode, dual-band bandpass filter with multiple transmission zeros is presented. The filter consists of an open stub loaded resonator (OSLR) and a short stub loaded resonator (SSLR). By utilizing the odd- and even-mode resonanc...
Due to the explosive growth of various wireless communication services, today's microwave communication systems often require multi-band operations. For example, global systems for mobile communications (GSM) operate at both 900 and 1800 MHz, IEEE 802.11a and IEEE 802.11b wireless local area networks (WLAN) products operate in the unlicensed industrial,...

Automated Cavity Perturbation Method for Measurement of Dielectric Constant

The cavity perturbation method is a well established technique for the measurement of dielectric properties of materials at microwave frequencies. This article presents an automated cavity perturbation technique at X-Band, using a VNA and LabVIEW softw...
Cavity perturbation techniques 1,2 have been widely used for the measurement of dielectric properties at microwave frequencies. The fundamental concept of this technique is that the presence of a small volume of dielectric sample in the resonant cavity will not significantly perturb the electromagnetic field around the loaded sample...
