다국어 초록 (Multilingual Abstract)
In this paper, a MIC beam steering antenna is designed by using the microstrip substrate whose dielectric constant is 2.45 and height is 0.10875cm.
In order to match the impedance of the antenna with free space, dimensions of the antenna are determined from the C.A.D. and Hammerstad formulae are used for calculating the width of microstrip and the rat-race hybrid ring phase shifter is used for the phase shift between antennas.
From this experiment, the antenna has ±200MHz bandwidth with the center frequency of 10.5GHz. The main beam of the antenna could be steeled by about 30 degrees by taking the distance of antenna 1 and 2 by □λ and the phase shift between them by zero and □λ radians. These experimental results were in good agreement with the theoretical values.
