Circularly Polarized Antenna Array using Sequential Rotation Technique:

In this project, circularly polarized antenna has been designed for the application domain of Direct Broadcasting Satellites (DBS) using sequential rotation technique. Using this technique, 2 GHz bandwidth has been achieved which is a necessity for efficient performance since DBS operational range is 10.7-12.7 GHz. In addition, good circular polarization and low VSWR over a wide frequency band has been achieved. The axial ratio approaches 0 dB at boresight with 0.47 GHz bandwidth making the antenna broadband both in terms of VSWR and axial ratio bandwidth.
