2. Description of the Related Art
In order to meet the market demand for high-speed information transmission, the telecommunication industry has already adopted multi-band high-frequency electromagnetic waves to transmit signals. In this development trend, telecommunication companies, network service companies and research entities in various countries conducted field tests and discovered signal transmission quality is significantly affected by building materials and building components because frequency bandwidths up to the high frequency spectrum are used. Even when building materials and building components are made of dielectric materials with low dielectric loss, reflection loss may still occur in certain electromagnetic spectrum due to mismatch between the material itself and the external dielectric constant. In one example in which glass without any coating is used in the air, typical glass would cause 2 dB to 4 dB of reflection loss in the environment of high-frequency communication. This means that 50% of the energy of electromagnetic waves is converted to the reflection loss due to the shielding of the glass during the transmission process. In addition, data protection and privacy have become universally important to the public in the process of communication deregulation. In addition to using methods such as passwords or encrypted transmissions, which are widely used today to protect the acquisition and decryption of transmitted data by unauthorized persons, it has become an important problem to be solved in recent wireless communication to block data or allow others to access the data by satisfying the transmittance of electromagnetic waves of specific frequencies for building components according to the user's needs.
In order to solve the signal attenuation problem caused by the materials and structures using the above-mentioned building components made of dielectric materials, various examples have been studied and may be summarized in certain ways according to different operational mechanisms. An internal antenna, an internal/external antenna containing a lead wire, a dielectric antenna, and a periodic conductive structure are included. The methods of installing the internal antenna, the internal/external antenna containing the lead wire, and the like are widely used in vehicle communication and in a building environment. According to the above scheme, a signal is received through an antenna, the received signal is amplified or not amplified according to the configuration of the system, and the processed signal is transmitted to the outside through a lead wire or an antenna. In some schemes, a dielectric surface is used as an antenna substrate, and an antenna for transmitting and receiving signals is manufactured through a patterned conductive layer. Specific examples may be found in patent documents such as U.S. Pat. Nos. 3,728,732, 4,849,766, 5,083,133, 5,821,904, 5,867,129, 6,121,934, 6,239,758, 6,661,386, 7,091,915, 8,009,107, 9,350,071, EP1343221, EP2581983, CN104685578B and CN105075008. In the periodic metal structure scheme, a periodic metal structure is simply fabricated on a dielectric so that the size of the metal structure is adjusted to generate a phenomenon in which the entire structure selectively transmits an electromagnetic wave of a specific wavelength. Thus, the above periodic metal structure is also called a frequency-selective surface. Related example may be found in patent documents such as JP2004053466, JP2011254482, U.S. Pat. Nos. 4,125,841, 6,730,389, 10,741,928, CN1561559, and CN104269586. However, all of the above-described schemes require a conductive structure for transmitting and receiving an electromagnetic wave signal or filter, and particularly, fail to switch and adjust the electromagnetic spectrum passing through the building components.

DESCRIPTION OF THE PREFERRED EMBODIMENTS
In order to understand the technical features, contents and advantages of the present invention, hereinafter, the present invention will be described using the form of representation of the embodiments in detail with reference to the drawings as follows with reference to the accompanying drawings. However, the drawings are only intended to supplement the specification as a gist, and may not correspond to the actual proportions and exact arrangements after implementation of the present invention. Accordingly, it will be noted that the drawings do not limit the scope of the claims to be actually implemented by the present invention upon interpretation related to the proportions and arrangement of the accompanying drawings.
Referring to FIG. 1, it shows an admittance diagram according to the related art. For example, the target component of εs=εr=6 (indicated by position 101) is arranged in an environment of εr=1 (indicated by position 102), an admittance value αs of the target component shifts from position 102 to position 103 along the circle in a clockwise direction as the thickness of the target component gradually increases from 0 to ts. Next, for example, a dielectric apparatus with a structure body formed of a first dielectric material having a dielectric coefficient of εs=εr=6 is selected and coupled to the target component to form a composite structure. As the thickness of the apparatus gradually increases from 0 to t1, the admittance value (αs+α1) of the composite structure would continue to shift clockwise along the circle form position 103 as illustrated in the figure, pass a phase thickness
at position 104 on a real part axis (Re) and cross a phase thickness n*π at position 105 on the real part axis (Re). In other words, t1 corresponding to the phase thickness n*π becomes the optimum thickness of the apparatus, so that the composite structure would have an improved transmittance in a specific electromagnetic wave spectrum. The value of n in the above two formulas is not a zero but a positive integer. When the multi-layer structure or positioning component is a dielectric and is located in an area through which the radio frequency signals may pass, the compensation analysis method is the same as the above method. In addition, when considering the bandwidth and production process in the actual application situation, an acceptable range of thickness variation may be within +/−25%.

Referring to FIGS. FIGS. 10A and 10B, graphs show the reflectance and transmittance when electromagnetic waves of 2 GHz to 6 GHz pass through glass with a thickness of 6 mm and a dielectric constant of 7. As shown in the drawings, the reflectance is −2.838 dB, −2.612 dB and −2.515 dB at operating frequencies of 3.5 GHz, 4.0 GHz and 5.0 GHz, respectively; and the transmittance decreases to −3.190 dB, −3.449 dB and −3.570 dB due to the reflection. In the evaluation condition of reflectance −10 dB bandwidth, the bandwidths of 3.5 GHz, 4.0 GHz and 5.0 GHz are zero.
Referring to FIGS. 11A and 11B, the graphs indicate the reflectance and transmittance when electromagnetic waves of 2 GHz to 6 GHz pass through glass having a thickness of 6 mm and a dielectric constant of 7 and the dielectric apparatus, the device, shown in FIG. 8A is coupled thereon. The material for fabricating the dielectric apparatus structure is a polymer material having a dielectric constant value of 2.5, and the structure body contains three cavities. The structure and thickness of each layer in a section of the structure body, sequentially from the bottom layer to the top layer of the coupled glass, are as follows: bottom layer (1.80 mm)/first chamber (0.22 mm)/spacer (3.00 mm)/second chamber (0.22 mm)/spacer (2.50 mm)/third chamber (0.22 mm)/top layer (2.50 mm). The frequency is switched by filler each chamber with water having a dielectric constant value of 80 as needed. According to the simulation when the chamber is not filled, the reflectance of 3.5 GHz, 4.0 GHz and 5.0 GHz is −4.586 dB, −5.465 dB and −5.895 dB, and the transmittance is −1.856 dB, −1.451 dB and −1.292 dB, respectively. In other words, it can be seen that the transmittance increases at 3.5 GHz, 4.0 GHz, and 5.0 GHz for electromagnetic waves after the apparatus is coupled to the glass. However, the bandwidth of each operating frequency still appears as zero at −10 dB reflectance. Accordingly, it is still not suitable for use as a normal signal. In the case of operating frequency of 5.0 GHz, and when only the first chamber is filled with water, the reflectance is −15.031 dB, the transmittance is −0.139 dB, and the bandwidth is 1.230 GHz; In the case of operating frequency of 4.0 GHz, and when only the second chamber is filled with water, the reflectance is −22.745 dB, the transmittance is −0.023 dB, and the bandwidth is 0.781 GHz; In the case of operating frequency of 3.5 GHz, and when only the third chamber is filled with water, the reflectance is −19.196 dB, the transmittance is −0.053 dB, and the bandwidth is 0.6773 GHz. Thus, it can be seen that filler different cavities with water can significantly improve the transmittance of electromagnetic waves at certain operating frequencies. Therefore, when the present method is applied, the operating frequency can be switched and the application requirements of high-frequency transmission can be implemented.
The admittance of the corresponding operating spectrum is analyzed through a structure body made of a dielectric material, so that the composite structure formed by coupling the dielectric apparatus according to the present disclosure to the building component may adjust the admittance value in block units, and accordingly, the transmittance of the composite structure can be improved in operating spectrum signals of different frequency bandwidths. In addition, the material filled in the chamber is adjusted according to the required signal, so that the purpose of switching the operating spectrum can be achieved.
The embodiments of the present disclosure are described above with reference to the accompanying drawings, but the present disclosure is not limited to the aforementioned specific embodiments. The specific implementation as mentioned above is merely indicative rather than restrictive. Equivalent modifications or changes made by a person of ordinary skill in the art under the implication of the present disclosure, without departing from the spirit and scope of the present disclosure, shall be included in the following claims.
