摘要

本研究是設計應用於IoT（物聯網）無線技術中Sub-1GHz之天線，主要藉由改變天線的面積、形狀等參數，進而導致天線頻率響應範圍產生變化。在模擬的過程中藉由電磁模擬軟體進行模擬，模擬出天線的參數，並做出歸納分析，作為實驗參考數據，確認其結果要符合Sub-1GHz頻帶的要求（0.86～0.928GHz）。我們也實現天線的實作，再以儀器量測，驗證實作天線是否與模擬一致，我們的天線使用厚度為0.8mm FR4基板，天線尺寸為76mm×25mm，模擬結果可用頻帶為0.84～1.22GHz，實測結果可用頻帶為0.86～1.13GHz。

In this study, an antenna is designed to be applied for sub-1GHz in IoT (Internet of Things) wireless technology. By changing the antenna area, shape and other parameters, the frequency response range of antenna is adjusted to the desired frequency band. In the process of simulation by electromagnetic simulation software, the parameters of the antenna are obtained. The results of simulation are confirmed to meet the requirements of the Sub-1GHz band (0.86 ~ 0.928GHz). The antenna was fabricated and measured by the instrument to verify that the implemented antenna was consistent with the simulation. Using FR4 substrate, the designed antenna size is 76mm×25mm, and the frequency band of the simulation result is 0.84~1.22GHz. The measured results of available frequency band is 0.86~1.13GHz, which meets the requirements of sub-1GHz applications.
