The problem is fine, the dipole arm low safety, antenna wiring space and gain characteristics of difference existing in the traditional dipole antenna structure, the multi application environment of spiral printed microstrip dipole antenna design and optimization method. The work structure of microstrip dipole antenna is initialized, and the spiral printed antenna with bold dipole arm is designed to reduce the occupied space of antenna line. Design the oscillator direction and the impedance characteristics of the oscillator, and derive the optimum structural parameters. Experiments show that the effective range in time, in less than Bobbi, within the effective range, the return loss is less than its direction, good symmetry, the antenna input in Bobbi and the return loss is more ideal, this antenna has good characteristics.
