Fdtd Analysis of a Conical Microstrip Antenna on Ebg Substrate

In this paper, the finite difference time domain method in spherical coordinates is used to analyze a microstrip conical antenna with a dielectric electromagnetic band-gap (EBG) structure as substrate. The voltage standing wave ratio, matched impedance, maximum gain as well as far-field radiation patterns, are presented. Our study suggests that the microstrip conical antenna on EBG substrate ho...

A Circuit Model to an Encoche Coplanar Antenna for a Radio Frequency Identification TAG

Received Mar1, 2013 Revised Apr 22, 2013 Accepted May 24, 2013 In this paper, Miniature Encoche Coplanar antennas are proposed. To validate our structure and to develop an analytic method to determine the geometry parameters, the Lumped theory is used. The proposed structure is simulated using ADS and then Compared to the electrical Model. The proposed circuit has the same resonant aspect when ...

A Data Envelopment Analysis Model with Triangular Intuitionistic Fuzzy Numbers

DEA (Data Envelopment Analysis) is a technique for evaluating the relative effectiveness of decision-making units (DMU) with multiple inputs and outputs data based on non-parametric modeling using mathematical programming (including linear programming, multi-parameter programming, stochastic programming, etc.). The classical DEA methods are developed to handle the information in the form of cri...

A Novel Design Approach for a 60 GHz Circularly Polarized EBG Antenna

This article focuses on the development of a high gain, broadband, circularly polarized Electromagnetic Band Gap (EBG) antenna operating at 60GHz. The designed antenna is configured with a superstrate based on a frequency selective surface (FSS) placed in front of a cross dielectric resonator antenna (XDRA), installed into a ground plane, which acts as an excitation source. A fast Leaky-Wave ap...
