【Abstract】 In this paper, a spot-focusing lens antenna operating at 8 mm frequency band is designed according to the measurement of the density of the plasma. The feasibility and validity of the scheme is demonstrated by means of simulation and test of the system. The theory in which high order modes can be ignored is powerfully testified. In addition, some academic and reference value for engineering design of antennas is also presented here.更多还原
