This paper presents a low-profile broadband antenna, which is composed of four parasitic patches placed between a printed-dipole radiator and a perfect electric conductor ground plane. The radiator and parasitic patches are realized on thin substrates. Owing to the presence of parasitic patches, the antenna performance improves significantly. The antenna design with the overall dimensions of 120 mm × 120 mm × 16.3 mm (0.64λo × 0.64λo × 0.087λo at 1.6 GHz) has a -10 dB impedance bandwidth of 1.465-1.740 GHz, a broadside gain of 8.5-8.8 dBi.
