Electrically short dipole with inductive reactance
I'm currently working with an electrically short, inverted V dipole (D ~ lambda / 15), and the simulated antenna impedance (shown in differential form below) seems to have several resonances in this low frequency range, meaning that the antenna looks inductive well below half a wavelength. I'm not an antenna expert and am having trouble understanding where that inductive bit may come from given the fact that sub-halfwave dipoles are supposed to be capacitive (perhaps it's something to do with having a bent dipole, but I don't have much intuition on bent dipoles).
