Experimental study of eight element circular array of circular patch antenna

摘要

Experimental analysis of eight element circular array of circular patch antenna is proposed for X-band of microwave frequency range. Radiation characteristics are measured and plotted. The far-zone field expressions for the array geometry are derived using vector wave function technique and pattern multiplication approach. The total field patterns are compared with the computed plots. Other important antenna parameters like Voltage Standing wave ratio and gain are also measured and plotted. The results are useful for phased array antenna systems in mobile communication.
