power in antenna pattern()
显示 更早的评论
Hello
can someone explain to me what the 2 types power and powerdb mean?
pattern(dipole, 150e6,'type','power')
pattern(dipole, 150e6,'type','powerdb')
also, i wonder how i can write an msi file (msiwrite()) for a 3 D pattern instead of 2D.
Thanks in advance.

Hi,
The ‘Type’ means the radiation pattern quantity to plotted with respect to azimuth and elevation. By default, its 'directivity'. ‘power’ is power specified in Watts and ‘powerdb’ is power specified in dB. As for the msiwrite it supports 2-D pattern as of now.

Hi,
As mentioned here on the third point that the source is a ideal voltage source of 1 Volt, this means that assumed input power is 1 Watt but it really depends upon the impedance of antenna.
There are more options available for parameter 'Type' which can plot the same radiation pattern with respect to gain and directivity. You may use 'gain' instead for 'power' for including the losses.
Hope it helps!
