Sažetak

(ne postoji na srpskom)
We investigate the influence of a wire-based impedance-matching network for an axial-mode helical antenna on the radiation pattern. This network, proposed in our previous work, comprises a single wire attached to the helix. We show that the matching wire, mounted on a tubular dielectric support and attached to the helix close to the reflector, does not degrade the antenna radiation pattern. We also investigate limitations of the equivalent thin-wire model proposed in our previous work.
