Charge distribution on metal or dielectric antenna or array surface
c = charge(object,frequency)
c = charge(object,frequency,'dielectric')
Calculate and plot the charge distribution on a bowtieTriangular antenna at 70MHz frequency.
h = bowtieTriangular; charge (h, 70e6);
Calculate charge distribution of linear array at 70 MHz frequency.
h = linearArray; h.NumElements = 4; C = charge(h,70e6);
Create a microstrip patch antenna using 'FR4' as the dielectric substrate.
d = dielectric('FR4'); pm = patchMicrostrip('Length',75e-3, 'Width',37e-3, ... 'GroundPlaneLength',120e-3, 'GroundPlaneWidth',120e-3, ... 'Substrate',d) show(pm)
pm = patchMicrostrip with properties: Length: 0.0750 Width: 0.0370 Height: 0.0060 Substrate: [1x1 dielectric] GroundPlaneLength: 0.1200 GroundPlaneWidth: 0.1200 PatchCenterOffset: [0 0] FeedOffset: [-0.0187 0] Tilt: 0 TiltAxis: [1 0 0] Load: [1x1 lumpedElement]
Plot the charge distribution on the antenna at a frequency of 1.67 GHz.
object— Antenna or array object
Antenna or array object, specified as a scalar handle.
frequency— Frequency used to calculate charge distribution
Frequency used to calculate charge distribution, specified as a scalar in Hz.
c— Complex charges
Complex charges, returned as a 1xn vector in C/m. This value is calculated on every triangle mesh or every dielectric tetrahedron face on the surface of an antenna or array. of antenna or array.
