Abstract


With the continuous development of science and technology , the increasingly widespread application of radio equipment in the fields of military, civilian . This will inevitably lead to memory in a variety of antenna in a limited space , resulting in deterioration of the electromagnetic environment within a limited space , resulting in decreased performance of electronic equipment . Therefore , effectively reducing the coupling between the antenna system electromagnetic compatibility key issues to be solved . Finitely conducting plane monopole antenna model, the application of the method of moments and the uniform geometrical theory of diffraction , finitely conducting plane the size of the gap on the antenna mutual coupling , reduce coupling the new method. The results show that reasonable to select the size of the conductive plane to enable the coupling between the antennas becomes smaller ; conductive plane on a half wavelength of the multi - slit may also be good to reduce the coupling between the antennas , and the width and spacing of the slits on the coupling little effect. The calculation results show that the proposed method of inhibiting antenna coupling is effective , and provides a new idea to reduce the antenna coupling .
