A dipole antenna (10) is provided herein with improved performance at a lower end of the antenna's operating frequency range. According to one embodiment, the dipole antenna (10) may include a plurality of antenna elements coupled to impedance transformer (30) via a pair of cones (60) and a pair of ears (70). The dipole antenna (10) may also include a high-pass matching network (20) specifically configured to improve antenna performance at the lower end of the operating frequency range. For example, a first stage of the matching network (20) (i.e., closest to the antenna elements) may include two series capacitors (C1, C2), while a second stage of the matching network (20) (i.e., furthest from the antenna elements) includes an inductor (L) coupled in shunt between the two capacitors (C1, C2). |
