Hi, everyone, I have a question about the omni-directional high gain antenna design.
Basically, the topology I want to use is a series of half-wavelength wires collinear aligned. The connections between them are spring coils. But how can I determine the dimension of the coil in order to make the phase of the half-wavelength section are in-phase?
Any references will be appreciated. Thanks.
