Measurement of a metamaterial antenna angular power reception performance utilizing Software Defined Radio

In wireless communication systems, angular positioning is an important aspect affecting the behavior of an antenna reception performance. In this study, a broadband, high gain rectangular microstrip patch antenna using planar-patterned metamaterial concept and its measured angular power reception performance are presented. The metamaterial antenna's −10 dB bandwidth is achieved as 2.42 GHz in the frequency range of 2.89-5.31 GHz with the peak gain of 5.56 dBi. Angular power reception performance of the proposed antenna is measured for different selected intervals in indoor and outdoor environments with the help of Software Defined Radio. The antenna is orientated vertically/horizontally and rotated in the azimuth Ø plane from 0° to 360° with angular resolution of ΔØ = 45°. The measured received power distributions are shown at angle versus distance and compared.
