Design And Analysis Of Elliptical Array Antennas

An Elliptical Array Antenna is composed of a number of equally spaced array elements on the geometry of the ellipse. The aim of the project is to study the feasibility of using Elliptical Array Antenna for use at base stations. Elliptical Antenna Artay arrangement has considerable effect on spatial correlation properties of multiple-input multiple-output (MIMO) wireless communication channels. In the method of beam steering and scanning Elliptical Arrays are presented. Theory, analysis, and computer simulation of the Elliptical Array Antenna are presented. The antenna array is designed using dipoles as array elements. The antenna is designed around 2GHz frequcacies with a bandwidth of 200MHz. The antenna is simulated using CST Microwave Studio and various radiation patterns are obtained by exciting different sets of array elements with different phase shifts. between them. Elliptical Antenna Arrays are characterized by high directivities, narrow beams, and low side lobe levels. The output radiation patterns obtained for the antennas designed show that Elliptical Array Antennas can be used to generate high gain and minimum side lobe levels. Also, the variations in the radiation patterns are studied for this array antenna using different number of elements and different excitations with different phase shifts between the elements. The results are tabulated for each design.Lecturer, Dept of TCE, SIR MVIT, Bangalore E-mail: sreeluperuru@gmail.com
