一種通訊電子裝置,其包含一接地元件及一天線元件。該天線元件位於一介質基板上並包含一輻射部及一天線接地面,其中該天線接地面電氣連接至該接地元件,該天線接地面並具有一槽縫,該槽縫可在該天線元件之操作頻帶之中心頻率附近產生一反共振模態,藉以改善操作頻帶之阻抗匹配,增加操作頻帶之操作頻寬。該輻射部包含一第一金屬部及一第二金屬部,其中第二金屬部之一端電氣耦合至該天線接地面上,且第二金屬部圍繞第一金屬部而延伸。 A communication electronic device which comprises a grounding element and an antenna element is disclosed. The antenna element is disposed on a dielectric substrate and comprises a radiation portion and an antenna ground. The antenna ground is electrically connected to the grounding element, and a slit is embedded in the antenna ground. The slit generates an anti-resonance mode near the center frequency of the operating band of the antenna, thereby effectively improving the impedance matching of the operating band to enhance the bandwidth of the operating band. The radiation portion comprises a first metal portion and a second metal portion. One end of the second metal portion is electrically coupled to the antenna ground, and the second metal portion is extended to surround the first metal portion.
