Hi.
I have simulated a dielectric λ/4 monopole antenna in (30-400 MHz).now I want to examine the results.
So,I extracted gain , directivity and efficiency versus frequency (30-300 MHz)
my directivity and gain are maximum in f=300 MHz (Dmax = 3.5 dB),while
my resonant frequency is 125 MHz.
actually, my efficiency is best in f=125 MHz (=70%) and
in other frequencies,efficiency is reduced (20-50%).
What do you think about the results?
