矩形反射柱体近旁天线辐射特性的计算——应用几何绕射理论

In this paper, the horizontal radiation characteristics of dipole and loop antennas adjaeent to a rectangular cylinder reflector are calculated by the application of GTD. The magnitudes of the direct field, the reflected field and the diffracted field from the edges of the cylinder at the field point are calculated and compared. The effects of the dimension of the cylinder, of the relative position of the antennas with respect to the cylinder and of the method of feeding to the resultant field pattern are analyzed. Using the method described, optimum design can be carried out to obtain the optimum omnidireetional radiation charqacteristics of antennas with reflector of this kind.
