Abstract

The antenna is designed as a 3D structure and is made from a conductible cylindrical antenna cone. The cone structure is realized using etching of elliptical slot array on the antenna. We use a conductible circular reflector under the proposed cone and increase the gain of the antenna. The proposed antenna provides effective bandwidth from 1GHz to 30GHz, but the gain of the proposed antenna is varying between 3dBi and 15dBi in the frequency band we are interested in. Geometrical details of the antenna are optimized numerically using parametric study using CST MWS Software Package. Once the optimal design is arrived at, the results are validated with another software package using HFSS Simulation Technology. The obtained results from both software packages agree very well.
