This paper discusses the design of a broadband Dielectric Resonator Antenna (DRA) tailored and modified appropriately for implementation as a textile wearable antenna in Body Area Networks (BAN). DRA addresses the issues of small size, wide bandwidth and low conductive loss in particular. Due to its vital credentials, DRA serves well to be a choice as a wearable antenna for on-body communication system...
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 two dielectric loaded planar antenna structures suitable for ultra wideband (UWB) or dual-band applications. The effect of the dielectric loading on the antenna resonant frequency and impedance bandwidth is investigated. Simulation and measured results for the return loss are presented and compared. The radiation patterns of the optimum design are also presented and...
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...
