用HFSS仿真天线.定义了激励端口,源的幅度按默认1w.仿真完成后,得出incident power=0.28w, accepted power=0.75646w, radiated power=0.7631w.
在HFSS的帮助里有:
1. The accepted power is the amount of time-averaged power (in watts) entering a radiating antenna structure through one or more ports. For antennas with a single port, accepted power is a measure of the incident power reduced by the mismatch loss at the port plane.
accepted power 应该等于incident power 减去端口平面的损耗. 那么accepted power应该小于incident power 才是,可仿真结果却不是这样,不知道为什么?
2. Incident power is the total amount of time-averaged power (in watts) incident upon all port boundaries of an antenna structure. Incident power is set at your discretion in the Edit Sources window.
Incident power 是在Edit Sources 中直接设置的,而我设置的是1w,不知道这个0.28w是怎么跑出来的,而且我发现我仿的所有天线的incident power 都是0.28w,
有哪位达人帮忙解决一下呀?

怎么没人关注呀?自己顶！期待达人！
