hi
here we can consider the ground plane as a field reflector
and it has a large effect on the radiation patterns and the resonance frequency
you cold notice that by using numerical methods for analyzing your microstrip
while most of the analytical methods assume that the ground plane is...
beside the expensive of substrate materials
there is other disadvantage for using a thicker substrate,a thicker on will cause the excitation of surface waves
Hi,
first your radiation pattern must be for the power ,not for E
second,your radiation pattern must be normalized, i.e.start from 0 dB
now, the beam width is the angle (on x axis) between tow points with power equal to -3dB,this is called half power beamwidth
or -3 dB beamwidh
which gives the...
the truncated make new paths for currents on the patch, so it change the way of radiation,i mean the radiating edge and the non radiating edge
that is similar to have more than one source to have circular polarization,I hope my answer will help you
