I'm interested in a low frequency (10 MHz - 100 MHz) radio receiver array, made up of crossed dipole antennas. I'm working on a design project mainly focused on the mechanical engineering side of making a low mass array printed on thin polyimide sheets for deployability. So, as I am not too familiar with antenna theory, I was hoping for some guidance.
First are the antennas. The goal is to keep everything small and light. The idea was to use thin copper or aluminum ribbons to make crossed dipoles on the polyimide sheets. The dipoles will be about 0.3m long to be $\ll \lambda$ at all wavelength.
Then there's the transmission lines. The maximum length of a transmission line for my setup is $\sim$ 30 m. I haven't been able to learn much about transmission lines in this frequency range. Specifically, I'm interested in what the dimensions have to be (length vs. $\lambda$, diameter or width, separation between lines) and what materials are good. Could it be as simple as more conductive wire?
Will microstrips lines be applicable here? That would be ideal, since they are thin and very light and could actually be printed on the film. Could microstrips even be used for the antennas themselves?
