Embodiment Construction
[0018] The present invention will be further explained below in conjunction with the accompanying drawings.
[0019] Such as figure 1 , figure 2 As shown, a strip dielectric patch filter antenna array includes two dielectric strips 1 , an H-shaped metal structure 2 , a dielectric substrate 3 , a metal ground 4 and a coaxial cable 5 . The H-shaped metal structure 2 is located on the upper surface of the dielectric substrate 3 , and the H-shaped metal structure 2 is composed of two metal strips 21 parallel to the y-axis and a metal strip 22 parallel to the x-axis. Two dielectric strips 1 are stacked above the dielectric substrate 3 , respectively located on both sides of the metal strip 22 on the x-axis and arranged parallel to the y-axis. The metal ground 4 is located on the lower surface of the dielectric substrate 3 , and the inner conductor of the coaxial line 5 penetrates from the bottom of the metal ground 4 and is connected to the center of the metal strip 22 .
