    • 本論文主要在研究用於FR1 頻段之路由器的天線設計，天線本體與搭接的主板呈90゜擺放，天線尺寸為100 x 24 x 0.8mm3，接搭主板的尺寸為80 x 100 x 0.8mm3，饋入方式是使用直徑1.37mm低損耗的同軸電纜線焊接在天線本體上，並搭配I-PEX接頭。天線可用於戶外small cell或安裝於一般的家用LTE路由器上或客戶終端設備 (CPE：Customer Premise Equipment)，接收低頻LTE訊號轉換成Wi-Fi訊號使用。
    本研究論文所設計的FR1頻段天線涵蓋的操作頻段有Low band (617 ~ 960MHz)：n8、n12、n26、n71與band (1427 ~1518MHz)：n74；Middle band (1710 ~ 2690MHz)：n25、n66、n41 涵蓋至 High band：n77 (3300~4200 )、n79 (4400~4900MHz)、n46 (5150~5925MHz) (如表1-1 ~1-3)[1]，天線設計是將訊號饋入以單極化天線為基礎並搭配兩路的接地分枝，首先將低頻頻段計算出總長路徑後模擬出RF1頻段之中最低頻率600MHz，再利用分枝方式將主波段所產生的倍頻移至相關頻段中的低頻(1700MHz與3300MHz)，並透過接地分枝方式增加頻段，以及適當的匹配設計將回波損耗調整至 -6dB。具體的天線設計以及實驗數據將會在本論文中詳細說明。

    In the thesis, the focus is mainly on the design of antenna for FR1-band Router. The antenna is placed at 90゜to the main board. The antenna dimension is 100 x 24 x 0.8mm3 and the main board dimension is 80 x 100 x 0.8mm3. The feeding method is using a 1.37mm-diameter low-loss coaxial cable soldered on antenna with an I-PEX connector. The proposed design can be used in outdoor small cells or general home LTE routers or CPE (Customer Premise Equipment) to receive low-frequency-band LTE signals and convert them into Wi-Fi signals.
    The operating frequency bands covered by the proposed antenna is listed as follows: Low band (617-960MHz): n8, n12, n26, n71 and band (1427-1518MHz): n74; Middle band (1710-2690MHz): n25, n66, and n41; High band: n77 (3300-4200MHz), n79 (4400-4900MHz), and n46 (5150-5925MHz). The proposed design is based on feeding the signal into a Monopole antenna with two ground branches. First we calculate the total length of the low frequency band and simulate the low-frequency resonance frequencies of 600MHz, and then use the branching method to move the frequency multiplier generated by the main band to the low frequency in the relevant frequency band (Middle band: 1700MHz & 3300MHz). By using the ground branches method and appropriate matching design, the return loss of -6dB is achieved. The experimental data will also be explained in detail in the thesis.
