The invention will be described in the following description with detailed steps and its composition. _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ The invention is described in detail below, and the preferred embodiment will be described in detail below, and the invention may be widely practiced in other embodiments, and The cost of the invention is not limited, which is based on the subsequent range. In the present invention, the solid-state, the straight-line, the _ dielectric, and the (four) are all divided into four (4) to form a dielectric f-resonance 11 antenna (thoracic_Res_ Αη_test). Therefore, the electric field of the slit towel in which the separated dielectrics f are turned over will be remarkably 'and the m factor (Q_fa_) is also lowered accordingly. The above two dielectric resonance n fractions have two grooves, and the entire resonance frequency is increased to increase the bandwidth. The hair duck reveals the effect of slits and grooves on the resonant frequency. The resonant frequency band of the private and modal modes can be adjusted to cover bands such as Radisson (3.4-3.7 GHz) and WLAN (5.15-5.35 GHz). Referring to the first A diagram and the -B diagram, it is not intended to be an antenna excitation structure, wherein the antenna system may be a dielectric f resonator antenna. The antenna is composed of a first resonating portion 15A and a second resonating portion (10), and the resonance portion 150 and the second resonating portion 17? The two identical rectangles are 2〇〇915658", and one of the resonant structures 150 is oscillated. The sum of the widths of the 丨70 and the slit 142 is the width of the two resonant structures 15〇, 17〇, the width is Δ, the height D, and the first-resonant portion 15〇 and the second resonating portion are carried by the slit 42 of the slit 42. The bottom and the sides of the two resonating portions 150, 170 are respectively inscribed with a notch, wherein the bottom portion One of the first tunnel 156 and the second tunnel 176 has a length of A and a degree of 沁, and the length of one of the first groove I% and the second groove 178 of the side is The two resonant structures 150 and 170 are disposed on a ground layer 13〇, wherein the ground layer (4) has a length of % and a width of A. The ground layer 13 is disposed on a substrate. 110, wherein the thickness of the FR4 substrate 11 为 is a dielectric constant of “4. A microstrip line 120 is transmitted through the sputum 132 to feed the two resonant structures 15 〇, 17 〇, wherein the microstrip line 12〇 extends beyond the length of the hollow portion 132, and the light stack length between the above-mentioned hollow portion D2 and the first-resonant structure 15〇 is ds ° The resonant frequency of the antenna 100 is mainly determined by the three-dimensional parameter e and the dielectric constant U of the two resonant structures 15〇, 17〇. Since the above-mentioned notch changes the electric field distribution inside the original two resonant structures 15〇, 170, the total fineness also changes. Since the slit m is perpendicular to the z component of the electric field of the two resonant structures 150, 170 modal, the electric field inside the slit 142 is thereby enhanced. Therefore, the resonant frequency and input impedance of the modality and the modality are significantly affected, and the input impedance of the antenna can be fine-tuned by the length of the extension of the microstrip line i2G and the length of the thin section 132, 丨 length B. In the two resonant structures 150, 170 located in the workplace, the electric and magnetic fields must conform to the Maxine's equation (M_eii, s-Μ·广~~^χΕ〇 =ja〇Mfi〇 (i)

VxHQ = jc〇QSEQ (2) where % is the resonant frequency. After the shape of the resonant structures 150, 170 is changed by the slit m2, the track 156, or the grooves 158, 178, the resonant frequency in the space ^/ will be an adult position function and the field distribution and resonance frequency are also Will be divided into the mouth of the Maxwell's equation and ω. Due to the interaction between the original field and the disturbance field, the two resonance structures 15 after the shape change (the resonance frequency of the U7G can be expressed as follows: „, yFxg+$x mutually) ‘W = — ----:~~

V wherein the above equation surface resonance system is affected by the reaction between the filament and the deformed dielectric resonator. The above equation also implies that if the disturbance = estimated is more accurate, the resonant frequency can also be predicted more accurately. For example, when a dielectric resonator has a small slit, the electric field perpendicular to the dielectric interface of the air will be significantly enhanced, and this phenomenon can be observed by simulation. Furthermore, 'disposed on the infinite „ground layer and the shape is the same—the dielectric resonator is equivalent to a single rectangular resonance in the free space, where the height of the rectangular resonator is Μ 'as the second Because the dielectric constant of the dielectric filament is much larger than the dielectric constant of air', in the first-order analysis, the dielectric interface of the air can be a L-conductor (Perfect MagnetI Conch, PMC) wall. The electromagnetic field modulus energy obtained by satisfying this boundary condition can be divided into shouting cranes. _, the material of the approximate perfect magnetic conductor can be more accurate than the _ shape result. Again, again ( Dielectric Waveguide Model, DWM) provides a more refined _, the structure of the structure is considered to be truncated in the direction of propagation - the part of the dielectric waveguide. The approximate strength of the perfect magnetic conductor is applied to the surface of the waveguide, and is cut off It is assumed in the section that total reflection exists, and the electromagnetic field forms a standing wave between the two sections of the ore. Next, the p-system with an odd (four) mode can be derived as follows: # 200915658 E0x = -A: zAcos(A:JCJv:)cos(A :y>;)sin(A:zz) EOy =0 E0z = kxAsm(kxx)cos(kyy)cos (kzz) y Asin(kxx)sin(k y)cos(kzz)

Therefore, in order to meet the secrets on A, the & component will be significantly more smooth than the slit width, and the number of antennas is: a=28mm, b=9mm, d=Wmm, e=20, c〇a=2mm, ^ ra mm, Ls=8mm, ds=7mm, Ws=Lg=70mm, 0.6mm ^ 〇) —i ic What you are. When the enthalpy is significantly increased, the resonance frequency and β ^ mode of t - interest are also slightly affected. It is worth noting that the 1 'heart will merge with the 72 匕 mode, but the two modes are; the plane has different radiation Field shape. According to image theory (imagethe〇ry), if the ground plane is infinitely large, the structure of ___, '^ and the four diagrams is equivalent. However, a resonant structure 15 〇, 17 被 by the slit 142 knives can be regarded as a dielectric resonator having a dielectric constant of the kind J. Since the slit 142 width /? is set to be much smaller than α, the rest of the interior of the single dielectric resonator 150, 170 is excluded except that the vertical electric field inside the slit 142 is enhanced to conform to the continuous condition of air dielectric. The distribution of the electromagnetic field is substantially the same as the distribution of the field inside the complete dielectric resonator without the slits 142. Therefore, 7^>u in the air slit 142 is dazzled. The modalities can be approximated as follows: & = m, 屹Asin«x)cos(心_y)cos(l/?/2) Ex=Ey=0 H = H0 13 (8) 200915658 The above Μ quantity is based on (4) Enhance the child. For the modality and the modality, the seam is very small and tends to be ♦. For the % modality, only the u-zone field is added, and a small value is generated, which is called between about 2 and 3. Therefore, the resonance frequency of the % mode is slightly increased. In contrast, the field of the (10) modality in the air slit 142 can be derived as follows: Εχ ~

Ez=Ey ~0 XH = H0 (9) «, and then equation =:: ^ ' and the rectangle with the slit of equation (9) is substituted into equation (3), then we can derive the "five" and private mode Resonance _. Fortunately, the radiation pattern can be determined by the electric field of the modal and the electric field on the cloth. In the z direction, positive and negative knives. Coffee (2_) radiation field on the upper surface of the dielectric resonator The shape zero value will appear in the direction of the electric field of if::, the resonance frequency of A in the "surface state will gradually approach, and ^" suppresses the taxi increase, and the (10) mode will merge. However, due to the above two bands, the band separation is better. The difference of (10) is that the redundancy and the A2 mode are based on the equation (3), the strict electric field is strong, and the % work scale 146 is arranged in (6) the modal 4&% negligible (6) mode The frequency of the connection 14 200915658 can be divided into 11-3⁄4 of the resonant frequency of the sound, if 1 K / 4 No. 4, and A is not, an air tunnel 146 is placed in the - Zhengkou scared work should be shown In the seventh figure, the upper; 2_146 half length of the 'L antenna 100's preferred three-dimensional size parameters Ma · a-28mm, b = 9mm, buckle 1 η mm, P = 〇 mm ' d ^ mm, sr = 2Q, ωα 2mm, ,, Cong, Yi~, 8mm > d=7mm ^ W=L=70mm > t=0.6mm, rnm~\\<mni ^

"i;=G·5~2 faces. With the increase of heart and sputum, the resonance frequency of ΐ£ΐ2桓2 亦 is also increased with $^4, 千力θI, and because of the vicinity of tunnel 140 at this time T£7U and 73⁄4 mode electric field age 彳 && electric field pregnancy 乂 U weak, so the resonance frequency of Hyun 2 and Hyun modal is almost unaffected. When the heights of the resonant structure (10) and the tunnel μ6 are both twice as large, the resonant structures of the sixth and sixth graphs are equal. Since the electric fields of the reui and 73⁄4 modes rotate with the y-axis, The electric field will be tangent to the interface of the air dielectric of tunnel I46. Therefore, e and & must assume e~e, $l'h = h, ° as for the 7^12 mode, because the tunnel 丨46 is located in the electric field is very close Where the value is, so the weight of the people in the tunnel 146 will increase, and can be approximated as follows:

Ez=Ey=0 ~ ~ (10) H = H0 15 200915658 Let equations (7) and (10) of minus=k/a be substituted into (3) to predict the offset of the modulo resonance frequency. The effect of the tunnel 146 on the resonant frequency of the 模^2 mode is greater than the effect on the resonant frequency of the 珲U and 73⁄4% modalities, and increases as a function of the thinness of the tunnel 146 by a factor of a. The preferred resonant frequency of the rw12 mode is 3.646 GHz. At ^±«/2, the 7^12 and 7^3 modes will approach the maximum value, and the resonant frequency of the above modes will also be affected by the adjacent grooves (5), 178. The first figure a shows a grounded common structure (10) in which two recesses 158, 178 are respectively disposed on both sides of the resonant structure 14A. The grooves 158, 178 described above will distort the distribution of the electric field and the antenna (4) will also be reduced to produce a wider frequency band. The ninth figure shows the increase of the resonance frequency of the above three modes by increasing the depth of the grooves (5), 178, wherein the preferred three-dimensional size parameters of the antenna brain are seven-strong, (four) coffee, and heart, 〇) a =2mm, La = lQmm, ι=8 η s 8_ ds - 7mm ' w~7〇, t=0.6mm ' (〇m^l.\5mm ^ s2=〇^2mm 〇

By equations (4) and (11) and equation (3), the resonant frequencies of the three modes of the dielectric resonator with grooves can be obtained. A preferred embodiment of the above-described dielectric resonator is (4) (4) face wmm 7mm, Ls=8mm, % = 2 face _ face. The resonance frequencies of %, 呵2, and NET 3 modes are 2 92 GHz, 3 58 and 4.62 GHz, respectively. In order to adjust the resonant frequency of private and private modes, the frequency band of AX (3.4-3.7GHz) and WLAN (5 i5_5 35GHz) can be used. The shape of the resonant structure (10) is designed as shown in Figure A, where the inner surface , (4) = such as m and (four) = 2_. By adjusting "the elongation L of the microstrip line m, and the length 4 of the hollow portion, the resonance structure is loaded with the feeding of the microstrip line 120" and the resonance frequency is slightly affected by the feeding structure. The tenth graph shows the return of measurement and simulation. The resonance frequencies of (4), (4) and modal 200915658 cover 3 375_3 93 GHz (15%), 46_479 GHz (4%) and 515415 GHz (6%), respectively, and the solid line The dotted lines are measured values and analog values. The first frequency band 191 in the tenth figure covers (3.4-3.7 GHz), and the third frequency band 193 covers the wlan (5-15-5.35 GHz) 'the preferred three-dimensional size of the above antenna 1 〇〇 The parameters are: β = 2 fine m, (four) Qing, buckle chest w, production; face, meaning = 4 coffee, face, d2 4mm, s2-2mm, sr = 20, h = 4mm, (〇a = 2mm, l,

The tenth-A diagram and the eleventh diagram B show the electric field distribution of the first frequency band (9) and the second frequency band 193, respectively, wherein the third resonance frequency band of about /=5 postal mails is the above; state. This—the separated resonant structure wind 170 can be viewed as a dual antenna that is placed next to the z-axis. The above is only the preferred embodiment of the present invention and is not intended to limit the scope of the invention.

When the wireless signal is input from the microstrip line 120, the wireless signal will pass through the hollow interface to the "vibration structure 140, when the power line of the wireless signal passes through the slit 142" due to the interface between the dielectric resonance structure and the air. The electric flux density means that the page is continuous' and the dielectric constant of the resonant structure is much larger than the line, so the electric field in the slit 142 is thus enhanced by several times, thereby making the electromagnetic wave more efficient and reducing the quality factor of the resonant structure. It can also effectively increase the bandwidth of the signal transmission. Therefore, by using the width of the slit, the width of the slit can be adjusted to a total of 4 weeks, and the bandwidth of the JL i曰 plus 73⁄4 state is used.

The narrow f ^42 can also be combined with the first tunnel 156, the second tunnel 176, the first groove 158 and the second groove 178 to move the fine 3 mode. The resonant frequency is lightly increasing the bandwidth of the 73⁄4 and 73⁄4 modes.
