Calculate current at feed for antenna or array
Excite a monopole antenna using plane wave. Calculate the feed current at 75 MHz.
h = planeWaveExcitation('Element',monopole, 'Direction',[1 0 0]) cur = feedCurrent(h,75e6)
h = planeWaveExcitation with properties: Element: [1×1 monopole] Direction: [1 0 0] Polarization: [0 0 1] cur = 0.0132 - 0.0133i
Calculate the feed current of a rounded-bowtie designed for operation at 2.4 GHz.
b = design(bowtieRounded,2.4e9); If = feedCurrent(b,2.4e9)
If = 0.0294 - 0.0012i
Calculate the feed current of a dipole antenna designed for operation at 70 MHz and 75 MHz.
feedCurrent(dipole, [75e6, 70e6])
ans = 1×2 complex 0.0136 + 0.0001i 0.0089 - 0.0034i
obj— Antenna or array object
Antenna or array object, specified as an object handle.
frequency— Frequency to calculate feed current
Frequency to calculate feed current, specified as a scalar integer in Hz.
