The electrical impedance characteristics around the resonant frequency of a thickness extensional vibration mode lead metaniobate sample were measured from ambient temperature up to 100degC. The material constants under various temperatures were determined by a precise theoretical fitting process of the measured electrical impedance. The effect of higher temperatures on the material properties are...
In this paper, the frequency response and radiation property of a printed monopole with respect to a ceramic dielectric load applied are investigated with the aid of the simulation software package CST Microwave Studiotrade. The variations in resonant frequency and impedance bandwidth (BW) with varying permittivity and dimensions of the ceramic are examined. Furthermore, a dielectrically loaded structure...
This paper presents the study of the effect of dielectric loading on the performance of printed monopoles. An initial antenna structure is presented and the alterations in its resonant frequency and impedance bandwidth with varying parameters of the ceramic brick, forming the load of the design, are investigated. Comparison with the results for different structures is also illustrated. General rules...
Two four-element planar arrays are reported utilising cylindrical dielectric resonators excited by probes at the HE/sub 11/spl delta// mode. The first array produces broadside radiation, whereas the second one provides maximum radiation at an elevation angle of /spl sim/40/spl deg/. The resonant frequency, radiation pattern, gain, unloaded Q-factor and impedance bandwidth of each array configuration...
