Embodiment Construction

[0047] Figure 1a A 3D view of the antenna 100 is depicted according to an embodiment of the invention. Figure 1b A partially exploded view of antenna 100 is depicted. The antenna 100 can meet the requirements of advanced multi-broadband and multi-polarization communication standards, for example, MIMO with dual polarization diversity in 5G mobile communication at two separated FR2 frequency bands. In addition, the antenna 100 can also be compact in size to provide a higher bandwidth-to-volume ratio.

[0048] Such as Figure 1a with Figure 1b As shown, the antenna 100 may include a plurality of mutually spaced radiators, eg, r[1] to r[4], which may collectively serve as pairs of dipoles. The antenna 100 may further include a plurality of conductive parasitic elements, eg, p[1] to p[4]. Optionally, the antenna 100 may further include one or more conductive coupling elements, for example, c[1] to c[4].

[0049] Each radiator r[n] (where n=1 to 4) may be conductive and co...

Abstract

The invention provides an antenna for multi-broadband and multi-polarization communication, and the antenna may include a plurality of radiators configured to jointly function as one or more dipoles,and a plurality of parasitic elements. Each radiator may be configured to contribute to resonances at two or more nonoverlapping bands, and may comprise an arm and a ground wall connecting the arm anda ground plane. The arm may comprise an arm plate and a folded arm. The ground wall may comprise a meandering portion causing a distance between the arm and the ground plane to be shorter than a length of a current conduction path along the ground wall between the arm and the ground plane. On a geometric reference surface, the projection of each parasitic element may extend between two gaps whichclamp a projection of an associated one of the radiators. According to the invention, the beneficial effects of multi-broadband and multi-polarization are realized.
