摘要
A dipole antenna is provided herein with improved performance at a lower end of the antenna's operating frequency range. According to one embodiment, the dipole antenna may include a plurality of antenna elements coupled to impedance transformer via a pair of cones and a pair of ears. The dipole antenna may also include a high-pass matching network specifically configured to improve antenna performance at the lower end of the operating frequency range. For example, a first stage of the matching network (i.e., closest to the antenna elements) may include two series capacitors, while a second stage of the matching network (i.e., furthest from the antenna elements) includes an inductor coupled in shunt between the two capacitors.
