Abstract: An electromagnetic wave guidance and beam reshaping structure is favorable to incorporate a radiation source antenna into an energy focusing system. The electromagnetic wave guidance and beam reshaping structure includes a substrate, a plurality of metal patterns and a plurality of hollow structures. The substrate includes a central portion and a peripheral portion that surrounds the central portion. The plurality of metal patterns are disposed on the central portion. The plurality of hollow structures are disposed in the peripheral portion. The metal patterns are axisymmetrically arranged with respect to a central axis of the substrate, and the hollow structures are axisymmetrically arranged with respect to the central axis of the substrate.

Abstract: A transparent antenna includes a substrate, an antenna grid layer, and a ground grid layer. The substrate has an electrically conductive hole extending from two opposite surfaced of the substrate. The antenna grid layer is formed on a surface of the substrate. The antenna grid layer includes a feeding portion and a transmission portion. The ground grid layer is formed on another surface of the substrate. The ground grid layer is coupled to the feeding portion of the antenna grid layer via the electrically conductive hole. An offset distance between a projection of a gridline of the antenna grid layer on the first surface and a projection of a gridline of the ground grid layer on the first surface is smaller than or equal to half of a difference between a line width of the antenna grid layer and a line width of the ground grid layer.

Abstract: The disclosure provides an integrated wideband antenna, comprising a first conductor layer, a first conductor patch, a second conductor patch, a feeding conductor structure and a signal source. The first conductor patch has a first coupling edge and a first connecting edge. The first connecting edge electrically connects with the first conductor layer through a first shorting structure. The second conductor patch has a second coupling edge and a second connecting edge. The second connecting edge electrically connects with the first conductor layer through a second shorting structure. The second coupling edge is spaced apart from the first coupling edge at a third interval forming a resonant open slot. The feeding conductor structure is located within the resonant open slot and has a first conductor line, a second conductor line and a third conductor line. The first conductor line is spaced apart from the first coupling edge with a first coupling interval. The second conductor line is spaced apart from the second coupling edge with a second coupling interval. The third conductor line electrically connects the first conductor line and the second conductor line. The signal source is electrically coupled to the feeding conductor structure. The signal source excites the integrated wideband antenna to generate one multi-resonance mode covering at least one first communication band.

Abstract: A highly-integrated multi-antenna array comprising a first conductor layer, a second conductor layer, a plurality of conjoined conducting structures, a plurality of slot antennas, and a conjoined slot structure is provided. The first conductor layer and the second conductor layer are spaced apart by a first interval, and are electrically connected by the conjoined conducting structures. Each slot antenna has a radiating slot structure and a signal coupling line, which partially overlap or cross each other. All radiating slot structures are formed at the second conductor layer. Each signal coupling line is spaced apart from the second conductor layer by a coupling interval and has a signal feeding point. Each slot antenna is excited to generate at least one resonant mode covering at least one identical first communication band. The conjoined slot structure is formed at the second conductor layer and connects with all radiating slot structures.
