摘要：An antenna device includes a ground plane, an antenna element, and a metalwall. The antenna element is having a distance of (m×λ/2-λ/4) away from the groundplane, where “m” is an integer which is equal or larger than “1” and “λ” is a wave
length of operating frequency. The metal wall is surrounding the antenna element. Oneend of the metal wall is attached to along the ground plane. The other end of the metalwall is forming an aperture with a height from the ground plane. The height of the metalwall is (n×λ/2), where “n” is an integer which is equal or larger than “m”.
