“…However, the samples have to be exactly machined and the accuracy is less than for resonator methods. Kent [4,5] experimentally developed a split resonator method that is non-destructive with resonator accuracy. It is composed of two cylindrical waveguides with their terminals shorted.…”

A low cost substrate material is reported using a polypropylene and nano-clay powder composite. The material characteristics, such as dielectric constant, loss tangent, lamination and thermalproperties have been determined. A patch antenna has beenfabricated using the developed substrate material and its performance has been characterized. IntroductionPatch antennas are used in mobile communications and, broadband wireless access, where product cost, process yield and manufacturability are critical parameters.

“…The original theory for this technique is summarized in references [41][42][43]. However, an improved theoretical model, based on the mode-matching method exists that properly takes into account the fringing fields in the sample region outside of the cylindrical waveguide sections [44].…”

This article presents the design of a mode launcher for launching TE011 mode in a cylindrical cavity. In the given design, TE011 mode is excited from the top wall of the cylindrical cavity using a rectangular waveguide. This type of top wall excitation of the cavity has been used keeping in view the application of the proposed launcher in coupling analysis of a coaxial magnetron. The proposed design is verified by launching TE011 mode in a cylindrical cavity, which is designed to operate at 9.3 GHz with the maximum quality factor. The value of quality factor obtained analytically is 31 030 and the same is verified by comparing it with simulation results obtained from CST and HFSS. Return loss and insertion loss of the mode launcher are obtained as 40.24 and 0.12 dB at 9.3 GHz, respectively. The frequency tunability of the cavity is also studied by changing the length of the cavity by making the bottom wall movable and a tuning range of 200 MHz is achieved. Performance of the top wall excitation is also compared with the conventional TE011 mode excitation from the rectangular waveguide through the side wall of the cavity, and both are in good agreement.
