Note (General): The harsh environment near Mercury (0.3 AU form the SUN) imposes 11 solar intensity on MMO HGA. As for HGA of spacecraft, a parabola antenna is common conventionally, but a planar antenna is advantageous in structure at solar flux concentration. Therefore, we adopted the helical array antenna exited by radial-line for HGA system in terms of planar antennas. The dimension of Helical Element was decided by the numerical analysis of the TLM method and the experiment. Furthermore, the electric characteristic test model of 1/2 size in terms of the area was made by using this element. We established adjustment technique of amplitude and phase by the half-size model. Based on the result, we produced 1/1 full-size model. This paper describes the basic characteristic of HGA first, and then the influences of heat-resistant material and structure on electrical characteristics.
