A wideband (4.94-6.959 GHz) four element rectangular dielectric resonator antenna array has been designed for 5.0 GHz WLAN and WiMAX band and its radiation characteristics determined through simulation studies using CST Microwave Studio software. Further, simulation results for power absorption in a homogenous bio-medium (muscle layer) in direct contact with the proposed antenna array is presented...
In this paper, the investigations of the rectangular dielectric waveguides with embedded metallic discontinuities in millimeter waves (70-130 GHz) region have been presented. The full wave simulation of the structure has been carried out using frequency division time domain method. The frequency response of the structure shows that it can be used in designing of a dielectric filter in the given frequency...
In this paper measurement of real part of permittivity and loss tangent of Zn1-x Mgx TiO3 (ZMT) ceramics in S-band of microwave frequencies is presented and the associated accuracy estimated. This approach is based on the measurement of transmitted power from the cavity at and off resonance. Details of the design and fabrication of the rectangular cavity and the input and output coupling are given...
