Abstract :
The mixed-potential integral equation is applied to a triangular patch surface model of the conical equiangular spiral antenna. The relationship between the input impedance characteristics and the geometrical parameters such as base radius, top radius, height, windings and angular-width of the arms are obtained. In order to obtain a wider band and stabler reflectance, when its geometrical parameters are restricted, the quantum genetic algorithm is applied and the geometrical parameters are optimized. A pint-sized of conical equiangular spiral antenna operating between 1GHz and 8.7GHz is obtained. It provides some theoretical guidance for the designing and miniaturization of this type of antenna.
