Embodiment Construction
[0011] The specific embodiment of the present invention is: as figure 1 As shown, the wide-beam broadband monopole rectangular antenna is composed of a rectangular conductor patch (1) printed on a dielectric substrate, a coplanar waveguide (2), an edge gradient structure floor (3) and an external coaxial connector (4 )composition. The lower end of the rectangular conductor patch (1) is smoothed and the bottom is slotted, and the coplanar waveguide (2) conduction strip is used as a feed source to excite the gap, and the lower end of the coplanar waveguide is connected to the inner conductor of the coaxial joint (4) , in order to externally connect the coaxial line, the gap between the ground plane at the lower end of the dielectric substrate and the coplanar waveguide is g=0.3mm, the edge gradient structure floor is printed on the lower end of the dielectric substrate, the edge is an exponential gradient structure, and the gradient form is y=e ax +b, where a is the gradient co...
