碩士 === 景文科技大學 === 電子工程系電腦與通訊碩士班 === 105 === In this paper, a miniaturized Wi-Fi dual-band antenna is proposed, which is suitable for Wi-Fi 2.4GHz (2400MHz ~ 2483.5MHz) and 5GHz (5150MHz ~ 5850MHz) for Wi-Fi in the world. In this paper, the antenna is based on monopole antenna, and uses the coplanar waveguide and the cross-feed mode to improve the monopole antenna bandwidth. The antenna structure core wire is a high frequency path and the ground wire is a low frequency path. High-gain dual-band antenna, and the use of asymmetric ground structure, the top load and parasitic components of the three design rules, so that the bandwidth to cover Wi-Fi complete operating frequency band. Ansoft HFSS is used to simulate and verify the antenna implementation, and the results of the variations of the antenna are analyzed. The asymmetric cross-fed double broadband antenna is presented in this paper.
