201112497 六、發明說明： 【發明所屬之技術領域】 本發明係有關於一種雙迴圈天線及多頻多天線模 組，尤指一種能夠產生良好天線性能之雙迴圈天線及多頻 多天線模組。 【先前技術】 傳統無線區域網路或802_lla/b/g/n橋接點天線大多 為外露式天線結構，最常見的形式為彼覆有塑膠或橡膠套 筒之偶極天線。這類型天線通常為單頻2.4GHz或雙頻 2.4/5GHZ天線，其天線主體高度通常為無線寬頻路由器 或集線器厚度的3倍高，並且天線έ體設置於一侧邊且外 露在機殼上方。使用者在操作上需先安裝天線，再調整天 線接收位置，天線亦容易遭受外力破壞，且佔據空間並破 壞美觀，特別是應用於多天線系統時。 因此，上述習知天線結構在量產至實際應用上，都需 一額外塑膠或橡膠套筒套接於天線外圍，因此提高天線的 製造成本。另外，這類型天線無法内藏在一般的無線寬頻 路由器或集線器内，亦即天線需外露在天線系統殼體外 部，因此習知結構大幅降低產品外觀的整體性及美感度。 另外，在 2.4/5.2/5.8GHZ 無線區域網路或 802.11a/b/g/n的内藏式天線設計上，大致為PIFA天線、 短路單極天線與平板天線（patch antenna )。一般内藏式 PIFA天線或短路單極天線，其天線最大增益在2.4與 5.2/5.8GHZ頻帶内通常分別只有約3與4dBi的大小，且 201112497 天線輪射場型少為垂向輕射（broadside radiation )。為達 成高增益天線（天線最大增益在2.4與5.2/5.8GHz頻帶内 至少需在6 dBi以上）’則需要廣泛使用平板天線或微帶 天線（microstrip antenna)。因為平板/微帶天線的輻射場 型為垂向輻射，具有指向性（directional )輻射場型，音 味著天線的最大增益比一般内藏式PIFA天線或短路單極 天線來的高。然而平板/微帶天線的結構需要兩層的最 構’ 一層為天線主要輪射體’另一層為天線的接地面，而 天線輻射體亦需較大的平面空間，並且因為天線不為平衡 式結構（unbalanced structure )，所以容易受到接地面效應 的影響。 緣疋’本發明人有感上述缺失之可改善，且依據多年 來從事此方面之相關經驗’悉心觀察且研究之，並配合學 理之運用，而提出一種設計合理且有效改善上述缺失之本 發明。 【發明内容】 本發明所要解決的技術問題，在於提供一種雙迴圈天 線及多頻多天線模組’其除了尺寸小、高度低、天線之間 隔離度小、輻射特性良好之外，亦不需額外增加一雙工器 電路，即可取代傳統外露式2.4/5GHZ雙頻橋接點 (access-point)天線。此外，本發明多天線模組可内藏於無 線寬頻路由器（router)或集線器（hub)内，以保持產品整體 外觀的完整性與美感度。 201112497 ^ 了解决上述技術問題，根據本發明之其中一種方 ^提供-種雙迴圈天線，其包括：—接地單元、一短路 I:射;讯號饋入單元:一第一迴陶單元及-第二迴 地單疋其中’該短路單元係具有至少-設置於該接 之短路接腳。該喊饋人單元係具有至少一盘上 I二ί'—ΐ路接腳相隔一預定距離且懸空於該接地單元 位於兮=距離之訊號饋入接腳。該第一迴圈輻射單元係 元的元上方—預定距離，其中該第—迴圈輕射單 述至Γ係分別電性連接於上述至少—短路接腳及上 第一二作^饋入接腳’並且該第—迴圈輕射單元提供-知作頻贡。該第二迴圈輻射單元係位於 方1定距離益且圍燒該第一迴圈輕射單元，其中：= =圈㈣單^的兩末端係分別電性連接於上述至少一短 接腳及上述至少一訊號饋入接腳 單元提供一第二操作頻帶。 第-爾射 ^ 了解決上述技術問題，根據本發明之其中一種方 數個=圈,4頻2線模組，其包括:一接地單元及複 接址…構。其中，該等雙迴圈結構係環繞地面對該 早π的幾何中心並且設置在該接地單元上，其 2，之雙迴圈結構的中心線彼此間的夾角係為相同，並 母二雙迴圈結構係包括：—短路單元、—訊號饋入單 單元單元及一第二迴圈輕射單元。該短路 號饋二單m接地單元上之短路•該訊 係具有至少-與上述至少-短路接腳相隔一 201112497 空？接地單元上方-預定距離之訊號饋 入接腳。㈣1㈣射單於… 定距離，其中該第-迴圈幸5射輩^°亥接地早疋上方一預 接於m, ^圈#田射早几的兩末端係分別電性連 且該第：=:Γ:接腳及上述至少-訊就婧入接腳，並 ㈣"^早70提供—第—操作頻帶。該第二遥圈 ==該？單元上方-預定距離並且圍繞該 二別=Γ該第二迴_射單元的兩末端係 刀別電性連接於上述至少一短路 。 二，接腳，並且該第二迴圈輻射單元提供一第二操:： 的内邻，f/、女凌於—天線系統殼體 數個雙迴圏17=wm-接地單元及複 接地單元的幾^該等雙迴圈結構係環繞地面對該 接也早凡的4何中心並且設置在該接 rr:r圈結構的中心線彼此間的夹角係為相同： 27雙㈣結構係包括：_短路單元、—訊號饋 弟一迴圈輻射單元及一第二迴圈輕射單元。該短路 置，地單元上之短路接腳。該訊 預定距離且:：： 述至少一短路接聊相隔- 疋s離且懸空於該接地單元上方一 ^ :接腳。該第一迴圈輻射單元係位於該接地單元 中該第一迴圈賴射單元的兩末端係分別電性連 、、至>、一短路接腳及上述至少一訊號饋入接腳，並 201112497 二ΤΓ轄射單元提供一第一操作頻帶。該第二迴圈 ^射早讀位於該接地單元上方_預定 = 第一迴圈輻射單元，其中爷筮一Α 固、m亥 分別電性5 / 一k圈輻射早几的兩末端係 刀別^連接於上述至少一短路接腳及上述至少 :入接腳’並且該第二迴圈輕射單元提供一第二心 ^ ° ' ’本發明的有益效果 因此，針對上述多頻多天線模組 在於： 1、在本發明所舉的例子巾，制三個獨立的雙迴圈 結構，每-侧立的雙迴騎構係甴—第—迴圈輻射單元 及-包圍該第-迴圈輻射單^之第二迴圈輻射單元所組 成。該第-迴圈輻射單元主要提供高頻5.2/5 8GHz頻帶 #作’並域第二迴圈輻射單元主要提供低頻2 4GHz頻 帶操作。 2在本發明所舉的例子中，每一個雙迴圈結構之第 一迴圈輻射單元及第二迴圈補單元可被料，以有效地 減少多頻多天線模組的整體高度，進而使得多頻多天線模 組可内藏於無線寬頻路由器（r〇uter)或集線器（hub)内，以 保持產品整體外觀的完整性與美感度 3、藉由控制每一個雙迴圈結構之訊號饋入接腳與短 路接腳之間距並且微調每一個雙迴圈結構之第一迴圈輻 射單元及第二迴圈輻射單元之間的距離，可獲得多頻多天 線杈組在2.4/5.2/5.8GHz無線區域網路頻帶内良好的阻抗 匹配（2:1 VSWR或l〇dB返回損失定義）。 201112497 〇 4、因為每一個雙迴圈結構之短路接腳鄰近不同天線 操作頻率之雙迴圈結構的訊號鎮入接腳，所以本發明可大 巾田降低每兩個具有不同天線操作頻率之雙迴圈結構之間 的耦合（mutual coupiing)，並且隔離度（is〇iati〇n)可確保在 -15dB以下之良好特性。201112497 VI. Description of the Invention: [Technical Field] The present invention relates to a double loop antenna and a multi-frequency multi-antenna module, and more particularly to a double loop antenna and a multi-frequency multi-antenna module capable of generating good antenna performance. group. [Prior Art] Conventional wireless local area networks or 802_lla/b/g/n bridge antennas are mostly exposed antenna structures, the most common form being a dipole antenna covered with a plastic or rubber sleeve. This type of antenna is usually a single-frequency 2.4 GHz or dual-band 2.4/5 GHz antenna. The height of the antenna body is usually three times as high as that of a wireless broadband router or hub, and the antenna body is placed on one side and exposed above the casing. The user needs to install the antenna first, and then adjust the receiving position of the antenna. The antenna is also vulnerable to external force damage, and takes up space and damages the appearance, especially when applied to a multi-antenna system. Therefore, the conventional antenna structure described above requires an additional plastic or rubber sleeve to be attached to the periphery of the antenna in mass production to practical use, thereby increasing the manufacturing cost of the antenna. In addition, this type of antenna cannot be embedded in a general wireless broadband router or hub, that is, the antenna needs to be exposed outside the antenna system casing, so that the conventional structure greatly reduces the overall appearance and aesthetics of the product. In addition, in the 2.4/5.2/5.8GHZ wireless area network or 802.11a/b/g/n built-in antenna design, it is roughly a PIFA antenna, a short-circuit monopole antenna and a patch antenna. Generally, the built-in PIFA antenna or short-circuit monopole antenna has an antenna maximum gain of about 3 and 4 dBi in the 2.4 and 5.2/5.8 GHz bands, respectively, and the 201112497 antenna wheel field is less vertical light (broadside radiation). ). In order to achieve a high-gain antenna (the maximum gain of the antenna is at least 6 dBi in the 2.4 and 5.2/5.8 GHz bands), a wide range of planar antennas or microstrip antennas are required. Because the radiation field of the flat/microstrip antenna is vertical, it has a directional radiation pattern, and the maximum gain of the antenna is higher than that of a conventional built-in PIFA antenna or short-circuit monopole antenna. However, the structure of the flat/microstrip antenna requires two layers of the most structure 'one layer is the main antenna of the antenna' and the other layer is the ground plane of the antenna, and the antenna radiator also needs a large plane space, and because the antenna is not balanced Unbalanced structure, so it is susceptible to ground plane effects. The inventor of the present invention feels that the above-mentioned deficiency can be improved, and based on years of experience in this field, the invention has been carefully observed and studied, and in conjunction with the application of the theory, a present invention which is reasonable in design and effective in improving the above-mentioned deficiency is proposed. . SUMMARY OF THE INVENTION The technical problem to be solved by the present invention is to provide a double loop antenna and a multi-frequency multi-antenna module that are small in size, low in height, small in isolation between antennas, and good in radiation characteristics, and An additional 2.4/5GHZ dual-frequency bridge-access point antenna can be replaced by an additional duplexer circuit. In addition, the multi-antenna module of the present invention can be built into a wireless broadband router or hub to maintain the integrity and aesthetics of the overall appearance of the product. 201112497 ^ To solve the above technical problem, according to one aspect of the present invention, a double loop antenna is provided, which comprises: a grounding unit, a short circuit I: a signal feeding unit: a first returning unit and - a second back ground unit in which 'the short circuit unit has at least - a shorting pin provided to the connection.

In order to solve the above technical problem, one of the squares of the present invention has a number of circles, a 4-band 2-wire module, and includes: a grounding unit and a complex address. Wherein the double loop structure is around the geometric center of the ground π and is disposed on the grounding unit, wherein the center line of the double loop structure is the same angle with each other, and the two pairs are The loop structure includes: a short circuit unit, a signal feed unit unit, and a second loop light unit. The short circuit is fed to the short circuit on the two m grounding unit. • The signal has at least - one at least one short-circuited with the above-mentioned short-circuit pin. 201112497 Empty? Above the grounding unit - the signal of the predetermined distance is fed into the pin. (4) 1 (4) Shooting at ... The fixed distance, where the first-loop is fortunately 5 shots ^°H grounded earlier than the first one is pre-connected to m, ^圈# The first two ends of the field are electrically connected and the first: =:Γ: The pin and the above-mentioned at least - the message is inserted into the pin, and (4) " ^ early 70 provides - the first operating band. The second remote circle == this? Above the unit - a predetermined distance and around the two sides = the two end of the second unit is electrically connected to the at least one short circuit. Second, the pin, and the second loop radiation unit provides a second operation:: inner neighbor, f /, female Ling - antenna system housing several double-returns 17 = wm - ground unit and complex ground unit The two loop structures are also around the ground and the center of the joint is also the same and the angle between the center lines of the rr:r ring structure is the same: 27 pairs (four) structure Including: _ short circuit unit, - signal feed brother a loop radiation unit and a second loop light unit. This short circuit is placed on the shorting pin on the ground unit. The message is predetermined distance and :::: At least one short circuit is separated by a distance - 疋s away from the grounding unit above a ^: pin. The first loop radiation unit is located in the grounding unit, and the two ends of the first loop radiation unit are respectively electrically connected, to>, a shorted pin and the at least one signal feeding pin, and The 201112497 II ΤΓ 射 单元 unit provides a first operating band. The second loop is pre-reading and located at the top of the grounding unit. _ predetermined = first loop radiating unit, wherein the two ends of the radiating unit are different from each other.

The beneficial effects of the present invention are therefore directed to the multi-frequency multi-antenna module described above. In the following example: In the example towel of the present invention, three independent double loop structures are constructed, each side-side double-back riding system 第-the first loop radiating unit and - surrounding the first loop radiation The second loop radiating unit of the single ^ is composed. The first-loop radiating unit mainly provides a high-frequency 5.2/5 8 GHz band. The second-loop radiating unit mainly provides low-frequency 2 4 GHz band operation. 2 In the example of the present invention, the first loop radiating unit and the second loop complement unit of each double loop structure can be materialized to effectively reduce the overall height of the multi-frequency multi-antenna module, thereby The multi-frequency multi-antenna module can be built in a wireless broadband router or hub to maintain the integrity and aesthetics of the overall appearance of the product. 3. By controlling the signal feed of each double loop structure The distance between the input pin and the short-circuit pin and fine-tuning the distance between the first loop radiation unit and the second loop radiation unit of each double-loop structure can obtain a multi-frequency multi-antenna group at 2.4/5.2/5.8 Good impedance matching in the GHz wireless local area network band (2:1 VSWR or l〇dB return loss definition). 201112497 〇4, because each short-circuited structure of the double-loop structure is adjacent to the signal of the double loop structure of different antenna operating frequencies, the present invention can reduce the double of each of the two antennas with different antenna operating frequencies. The coupling between the loop structures (mutual coupiing), and the isolation (is〇iati〇n) ensures good characteristics below -15dB.
