A transparent electromagnetic wave focusing device is provided, which includes a plurality of metamaterial unit cells arranged to form a metamaterial array plate, and each metamaterial unit cell includes a plurality of metal layers and a plurality of transparent substrates stacked alternately. Each of the metal layers has a comb-tooth pattern, and the plurality of metamaterial unit cells correspond to a plurality of comb-tooth pattern combinations, respectively. The metamaterial array plate has an incident surface and an exit surface opposite to each other, and for an incident electromagnetic wave with a predetermined operating frequency band incident from the incident surface, the metamaterial unit cells correspond to a plurality of compensation phase differences, such that the incident electromagnetic wave that passes through the exit surface are focused on a reference point. The comb-tooth pattern combinations vary with the corresponding compensation phase differences.

An antenna system includes a dielectric substrate, a ground element, and a first antenna element. The dielectric substrate has a first surface and a second surface, which are opposite to each other. The ground element is disposed on the first surface of the dielectric substrate. The first antenna element includes a first radiation element, a feeding radiation element, a second radiation element, and a shorting radiation element. The first radiation element has a feeding point, and is disposed on the second surface of the dielectric substrate. The feeding radiation element is adjacent to the first radiation element. The second radiation element is coupled to the feeding radiation element. The second radiation element is further coupled through the shorting radiation element to the ground element.

Antenna system

An antenna module and a wireless transceiver device are provided. The wireless transceiver device includes an antenna module. The antenna module includes a circuit board and at least one antenna array. The at least one antenna array defines a midline. The at least one antenna array includes a plurality of antenna elements and a signal feeding line. Each antenna element includes a feeding branch and a radiating portion. The radiating portion is coupling to the feeding branch, and the radiating portion is exposed on the upper surface of the circuit board. The signal feeding line is arranged in the circuit board and is perpendicular to the midline, and the signal feeding line is coupling to the feeding branch. The radiating portion defines an extension line along its extension direction. There is an included angle between the extension line and the midline.
