REVIEW ON THE Ku BAND DBS PLANAR ANTENNAS AND THEIR CURRENT PROGRESS
Ku波段DBS平面天线发展综述

Over past ten years, the Ku-band broadcasting satellites had been sent into orbit by some countries and regions such as Japan, Western Europe and Northern America, etc. Also, a series of business for Direct Broadcasting Satellite (DBS) had been carried out. Those situations have accelerated the development of the receiving techniques for television broadcast by satellites, especially, the development of the small-size planar antennas. This paper discusses the basic principle, construction and features of small-size planar antennas. This paper also gives some technical parameters of the small-size planar antenna developed both at home and abroad. On the basis of the microstrip antenna, this paper summarizes all sorts of small-size planar antennas presented at several countries. At last, this paper explores the necessity to develop small-size planar antenna in our country and proposed the current urgent task for us to do.
