Abstract

The 4.5m polar axis antenna with polar Axis mount and dual circular polarization ultra-wideband feed over 0.4-2GHz for China Spectral Radio Heliograph (CSRH) array is presented in the paper. The CSRH array and specifications of 4.5m polar axis antenna are introduced. The detailed design procedure about antenna system together with the structure of polar Axis mount, ultra-wideband feed, parabolic reflector and consideration for practical installation are described. The voltage standing wave ratio (VSWR) and radiation patterns of the feed for 4.5-m antenna have been tested, and the measured efficiency of the 4.5-m reflector antenna is better than 40%, The performance fulfills application requirements.
