Design of smart antenna using waveguide-fed pyramidal horn antenna for wireless communication systems

Abstract

The design of smart antenna using waveguide-fed pyramidal horn antenna gives a better system performance of directional radiation beam pattern with a high gain and wide impedance bandwidth. At higher frequencies, the effects of interference cannot be overemphasized as the quality of signal is reduced significantly. To overcome this drawback on the propagation of signal, smart antenna offers the mitigation of interference on signal transmission and reception as it combines its different elements and digital signal processing capacity. This research work presents an innovative approach of designing smart antenna using a waveguide-fed pyramidal horn antenna for wireless communication systems. For the optimum performance of smart antenna at higher bandwidth for this research work, waveguide-fed pyramidal horn antenna possessed unique electrical features with centre frequency of 30 GHz, distribution taper of all side-lobes equal (Dolph-Chebychev), side-lobe level of 14 dBi, orientation (elements are located along the specified axis) of X.
