基于S参数法的车载天线耦合度分析
Coupling Degree Analysis Between Vehicle-mounted Antennas Based on The Method of S-parameters
摘要
Abstract
In order to research the electromagnetic compatibility between vehicle -mounted antennas,the real model of an armored vehicle is simplified by ANSA,and the simplified model of the electromagnetic simulation is established by the real dimension of an armored vehicle in this paper. Based on a generalized theory of S-parameters,the formula of the electromagnetic coupling degree between transmitting and receiving antenna is given. For the perfect conductor plan and an armored vehicle,the EM coupling degrees between transmitting and receiving antenna are simulated by CST respectively. With the decrease of the interval between transmitting and receiving antenna,the EM coupling degrees between vehicle-mounted antennas are nonlinear and increased. The minimum of EM coupling degrees are at the resonance frequency of 62.5 MHz and the both maximum occurs nearby the resonance frequency,the EM coupling degrees are relatively larger between the transmitting antenna at the third harmonic frequency and the receiving antenna.关键词
