Abstract
An antenna system includes a first antenna element, a second antenna element, a dielectric substrate, a first reflective plate, and a second reflective plate. The first antenna element and the second antenna element are disposed on the dielectric substrate. The first reflective plate is adjacent to the dielectric substrate. The second reflective plate is coupled to the first reflective plate. A first angle is formed between the first reflective plate and the second reflective plate. The antenna system provides a relative large HPBW (Half-Power Beamwidth).
