Field Distribution Analysis Based on Improved Differential Algorithm for Dual Port Radiation Device

Abstract

With the continuous development of science and technology, the requirement of signal source is higher and higher. Single port signal source is difficult to meet experimental requirements of radiation spatial field distribution. In this paper, a dual port radiation device for changing the field distribution is proposed. The dual port radiation device is mainly composed of the DC to 6 GHz experimental radiation device, amplifier, attenuator, and the phase shifter. After adding two different excitation signals to the dual port, the field distribution of the radiation device is calculated by improved differential algorithm and simulated by CST software. The simulated results are in good agreement with the calculated results. The innovation of this research lies in the dual port and controlling the field distribution of the radiation space freely.
