Circular Ring Patch Antenna Array at 20.2 GHz with Circular Polarization in SATCOM Applications Using CST

Abstract

AbstractHigh directivity antennas which fetches for satellite communication applications are preferred to be array antennas. Providing greater directivity array of ‘n’ elements is designed in which circular ring’s intrinsic geometry is chosen that leads to circularly polarized waves with high gain and increased radiation efficiency (Devika et al. in Indian J Sci Technol 9:38, 2016). This paper presents the introduction of phased array antenna, design of single micro strip element in the array, and methodology to achieve circular polarization which helps in satellite communication. This paper presents the circular patch structural design in CST studio that helps in improved performance characteristics of the antenna used for practical applications in satellite communications (Devika et al. in Indian J Sci Technol 9:38, 2016). This antenna provides outstanding performance regarding side lobe signal level, half power beam width (HPBW), gain bandwidth, cross polarization, and axial ratio bandwidth at the center frequency of 20.2 GHz.KeywordsPhased arraySatelliteMicro stripCircular patch
