Numerical investigation on compact multimode dielectric resonator antennas of very high permittivity
نویسندگان
چکیده
An electrically small antenna based on a dielectric resonator antenna (DRA) is investigated. Two wellknown simulation techniques, the finite element method and the finite integration technique have been applied to study a low volume high permittivity DRA. It is demonstrated that the design of a compact size and wide frequency coverage DRA for 2.4–2.5 GHz ISM frequency band is possible by proper selection of the resonator shape in combination with appropriate resonant modes. Numerical results for one particular antenna design are reported.

متن کاملNumerical Modeling and Experimental Study of Probe-Fed Rectangular Dielectric Resonator Antenna (RDRA) Supported by Finite Circular Ground Plane
Dielectric Resonator Antennas (DRAs) have received increased interest in recent years for their potential applications in microwave and millimeter wave communication systems. DRAs are normally used with the support of a ground plane. The radiation and impedance properties therefore depend not only on their physical dimensions and dielectric properties, but also on the size of the ground plane. ...
متن کاملDevelopment of Polymer-based Dielectric Resonator Antennas for Millimeter-wave Applications
The goal of this paper is to use polymer-based materials (instead of hard ceramics) in fabrication of dielectric resonator antennas at millimeter-wave frequencies. The soft nature of polymers facilitates machining of antennas, while the low permittivity of polymers naturally enhances the bandwidth. More importantly, advantageous properties (e.g., flexibility and photosensitivity) of some polyme...
متن کاملCompact Wavelength Demultiplexer via Photonic Crystal Multimode Resonators
Wavelength demultiplexers based on photonic crystal resonators are attractive, since they may be realized in very small sizes. However, existing designs have a limitation on the size, since they all require one resonator for each wavelength and these resonators must be separated. As a possible approach to reduce the size further, we show that a single multimode resonator may be used to separate...
