Log Periodic Dielectric Resonator Antenna for Broadband Applications
نویسندگان
چکیده
A Log Periodic Dielectric Resonator Antenna (LPDRA) for broadband applications is presented. In this paper, a broad bandwidth antenna is formed by application of log periodic technique to the series fed electromagnetically coupled rectangular overlaid dielectric resonator array. This Log Periodic DRA is simulated using a CST microwave studio suite 2010. The simulated results show wider impedance bandwidth covering the frequency range of 6.4 GHz to 11.1 GHz with a VSWR less than 2 and radiation efficiency greater than 95 %. Its maximum gain is 7.2 dBi. Parametric studies of the antennas with CST microwave based design data and simulated results are presented here. The scaling factor of 1.05 has been chosen for this design.

A Novel Circularly polarized dielectric resonator antenna with Branch-Line Coupler and Log-Periodic Balun
A new shaped circularly polarized dielectric resonator antenna (CP DRA) is studied with branch-line coupler and log-periodic balun for the GPS application. Since the coupler and balun are located under the DRA, it does not increase the footprint of the antenna, as a result the system is very compact. Two configurations are considered in this paper. In the first configuration, an external 50Ω lo...
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. ...
