1. An antenna system, comprising:
a first antenna element;
a second antenna element;
a dielectric substrate, wherein the first antenna element and the second antenna element are disposed on the dielectric substrate;
a first reflective plate, disposed adjacent to the dielectric substrate; and
a second reflective plate, coupled to the first reflective plate, wherein a first angle is formed between the first reflective plate and the second reflective plate;
wherein the antenna system provides an HPBW (Half-Power Beamwidth) from 90 to 180 degrees;
wherein the antenna system covers an operational frequency band;
wherein a length of the first reflective plate is calculated using the following equation:
