Abstract

Wireless communication is the prime area for research now a day in the world. In wireless communication systems Antenna is a prime element for both transmission and reception. Antenna is a main source of electromagnetic energy. It is a transducer which converts electrical energy in to electromagnetic energy. At microwave frequencies applications, because of the ruggedness Horn Antennas are preferred, it gives high gain values. In the present work an attempt has been made to design a pyramidal horn antenna at c- band. The design was simulated using Matlab. The characteristics of horn antenna are depending upon its aperture lengths and how the horn antenna characteristics like beam width, side lobe levels, gain are varied with respect to their lengths are also studied. Array antenna distributes its electromagnetic energy in to free space in different directions. The gain of a single antenna element is not sufficient for most applications. Arrays are often used to increase the gain, directivity and reduce the beam width. Horn linear and planar array patterns are plotted in the present work in both rectangular and polar forms. Array antenna radiation patterns are extremely useful in both airborne as well as ground based applications.
