这个只是一个设置经验而已
微带天线,设置中心频率即可,这个貌似和谐振频率没太大关系,但谐振频率好像应该在中心频率附近
好的 多谢师兄 赐教
HFSS 仿真微带天线中,我对Analysis下的setup 里的 solution frequency 的设置感到疑惑。书上说 这个频率设置的越高,计算结果越精确 。请问各位大侠,是这样的吗?这个频率的设置和谐振频率有关系吗?设计一个天线,这个频率该怎么设置。
Broadband Structures
For broadband structures, the end frequency should be used since the finer
mesh should be valid at all lower frequency points.
Filters
For filters or narrow-band devices, a frequency within the pass-band or
operating region should be used since in the stop-band the E-field is only
present at the ports.
Fast Frequency Sweeps
For Fast Frequency Sweeps, typically use the center of the frequency
band. The Fast Frequency Sweep uses the mesh/solution at the adaptive
frequency point. Since the error in the Fast Frequency Sweep typically
increases as you move away from this point, the center of the frequency
band is usually the preferred solution frequency to extrapolate the entire
band from. It is also important to center the frequency sweep around a
center point that will produce an adequate mesh. This is especially true for
very high Q devices such as narrow-band filters. If the center frequency is
not in the filters pass-band, the bandwidth and resonant frequency will not
be accurate.
求解频率与最终的网格结果有关系,所以也间接影响到最终的仿真结果精度的,如果自己对结果不放心,可以去不同的求解频率算一遍,比较一下取其合理设置值~
是的,自己操作一下最好。
