Fig. 1 shows a schematic view of a Contact Lens 100 according to an embodiment of the invention. The contact lens 100 may support communication functions. In the embodiment of fig. 1, the contact lens 100 comprises: a Display Unit (Display Unit) 110, an antenna element (ANTENNA ELEMENT) 120, a first Ring-shaped metal Structure (Ring-SHAPED METAL Structure) 130, a second Ring-shaped metal Structure 140, and a transparent element (TRANSPARENT ELEMENT) 150. It must be understood that although not shown in fig. 1, the contact lens 100 may further include other elements, such as: a Processor or (and) a power module (Power Supply Module).

The shape and kind of the display unit 110 are not particularly limited in the present invention. The antenna element 120 is adjacent to the display unit 110. It should be noted that the term "adjacent" or "adjacent" in this specification may refer to the corresponding elements having a pitch smaller than a predetermined distance (e.g., 10mm or less), but generally does not include the case where the corresponding elements are in direct contact with each other (i.e., the pitch is reduced to 0).

The antenna element 120 may cover an operating frequency band, wherein the operating frequency band may be greater than or equal to 60GHz. Thus, the antenna element 120 may support at least broadband operation for millimeter wave (MILLIMETER WAVE, mmWave) or megahertz (Terahertz, THz) communications. In some embodiments, the Antenna element 120 may be a monopole Antenna (Monopole Antenna), a Dipole Antenna (Dipole Antenna), a Loop Antenna (Loop Antenna), a helical Antenna (HELICAL ANTENNA), a patch Antenna (PATCH ANTENNA), a planar inverted-F Antenna (PLANAR INVERTED F ANTENNA), or a chip Antenna (CHIP ANTENNA), but is not limited thereto.

Both the display unit 110 and the antenna element 120 may be surrounded by a first annular metal structure 130. In addition, the first annular metal structure 130 may be surrounded by the second annular metal structure 140. In some embodiments, both the first annular metal structure 130 and the second annular metal structure 140 are Floating (Floating) and separate from each other. For example, the transparent element 150 may be made of a hydrogel (Hydrogel) material, but is not limited thereto. The display unit 110, the antenna element 120, the first annular metal structure 130, and the second annular metal structure 140 may all be disposed on the transparent element 150.

Based on the actual measurement results, each of the first annular metal structure 130 and the second annular metal structure 140 may act as a Director (Director) for the antenna element 120. For example, the first and second annular metal structures 130 and 140 may be used to correct both the X-axis radiation and the Y-axis radiation of the antenna element 120 to be approximately Z-axis radiation, but are not limited thereto. With this design, the Radiation pattern (Radiation Pattern) of the antenna element 120 can be adjusted by properly configuring the first loop metal structure 130 and the second loop metal structure 140, so that the overall Radiation Gain (Radiation Gain) of the contact lens 100 can be improved.

The following examples describe various configurations and detailed structural features of the contact lens 100. It is to be understood that the drawings and descriptions are proffered by way of example only and are not intended to limit the invention.

Fig. 2 shows a top view of a contact lens 200 according to an embodiment of the invention. Fig. 3 shows a partial view of a contact lens 200 according to an embodiment of the present invention. Please refer to fig. 2 and 3 together. Fig. 2, 3 are similar to fig. 1. In the embodiment of fig. 2, 3, the contact lens 200 comprises: a display unit 210, an antenna element 220, a first annular metal structure 230, a second annular metal structure 240, and a transparent element 250. The contact lens 200 may be applied to an eyeball (Eyeball) 260, where the eyeball 260 includes a Pupil (Pupil) 270 and an Iris (Iris) 280. It should be noted that the eyeball 260 is not part of the contact lens 200.

The display unit 210 may substantially take the shape of a hexagon. The antenna element 220 is adjacent to the display unit 210. In detail, the display unit 210 includes a metal sidewall (Sidewall) 215, wherein the metal sidewall 215 can be used as a Reflector (Reflector) of the antenna element 220. In other words, the metal sidewall 215 of the display unit 210 can also be used to fine tune the radiation direction of the antenna element 220.

In some embodiments, a first distance D1 between the antenna element 220 and the display unit 210 (or the metal sidewall 215) is less than or equal to 0.25 times the wavelength (λ/4) of the operating band of the antenna element 220. The foregoing range of the first distance D1 helps to optimize the reflection effect of the metal sidewall 215 of the display unit 210 according to the actual measurement result.

Both the display unit 210 and the antenna element 220 may be surrounded by a first annular metal structure 230. The first annular metal structure 230 may be surrounded by the second annular metal structure 240. The display unit 210, the antenna element 220, the first annular metal structure 230, and the second annular metal structure 240 may all be disposed on the transparent element 250. For example, the first annular metal structure 230 may exhibit a smaller annular shape, and the second annular metal structure 240 may exhibit a larger annular shape, but is not limited thereto. The first annular metal structure 230 and the second annular metal structure 240 may share a common center, wherein the display unit 210 may be located approximately at this center.

In some embodiments, a second distance D2 between the first loop metal structure 230 and the second loop metal structure 240 is between 0.1 times and 0.2 times the wavelength (λ/10-2λ/10) of the operating band of the antenna element 220. The aforementioned range of the second distance D2 helps to optimize the guiding effect of the first ring-shaped metal structure 230 and the second ring-shaped metal structure 240 according to the actual measurement result.

In some embodiments, the diameter E3 of the first annular metal structure 230 is greater than a pupil diameter E1 of the eyeball 260. In other embodiments, the diameter E3 of the first annular metal structure 230 is larger than an iris diameter E2 of the eyeball 260, so that the first annular metal structure 230 and the second annular metal structure 240 can be prevented from shielding the eyeball 260.

In some embodiments, each of the first annular metal structure 230 and the second annular metal structure 240 is an energy storage element (Energy Storage Element). For example, the energy storage device may be a thin film photovoltaic cell (Thin Film Photovoltaic Cell), but is not limited thereto. With this design, the guides of the antenna element 220 can be integrated with the corresponding energy storage elements, thereby enabling the overall size of the contact lens 200 to be reduced. The remaining features of the contact lens 200 of fig. 2 and 3 are similar to those of the contact lens 100 of fig. 1, so that similar operational effects can be achieved in both embodiments.

For example, each of the radiation portions 421, 422, 423, 424 may have a circular arc shape, but is not limited thereto. It should be noted that the total number of the radiation portions 421, 422, 423, 424 can be adjusted according to different requirements. In some embodiments, a first distance D3 between the display unit 410 and each of the aforementioned radiating portions 421, 422, 423, 424 may be less than or equal to 0.25 times the wavelength (λ/4) of the operating band of the antenna element 420. Both the display unit 410 and the antenna element 420 may be surrounded by a first annular metal structure 430. The first annular metal structure 430 may be surrounded by a second annular metal structure 440. The display unit 410, the antenna element 420, the first annular metal structure 430, and the second annular metal structure 440 may all be disposed on the transparent element 450.

In addition, a second distance D4 between any adjacent two of the first annular metal structure 430, the second annular metal structure 440, the third annular metal structure 460, and the fourth annular metal structure 470 may be between 0.1 times and 0.2 times wavelength (λ/10-2λ/10) of the operating band of the antenna element 420. The remaining features of the contact lens 600 of fig. 6 are similar to those of the contact lens 500 of fig. 5, so that similar operational effects can be achieved in both embodiments.
