本論文提出適用於無線區域網路之新型電磁相容晶片天線設計，本新型天線包含三種不同結構的設計且其操作頻寬均涵蓋無線區域網路2.4 GHz之頻寬要求（2:1 VSWR）。由於本新型晶片天線具有電磁相容的特性，使得該天線設計適合應用於行動通訊裝置，如智慧型手機或個人數位助理手機中。由於使用新的天線接地面結構，讓天線本身可能產生在周圍的電磁洩漏場量能夠大幅的減少甚至被忽略。而當射頻屏蔽金屬盒或其他電路元件在相當靠近天線的情況下，本新型天線的操作特性幾乎不受影響。換句話說，實際應用時在天線和其他電路元件間不用一需要的隔離間距。因此本論文提出的新型天線設計可與其他鄰近的元件作緊密地整合於行動通訊裝置中。對於該新型天線詳細的量測與模擬數據在本論文中將會說明與討論。

Novel chip antennas having an attractive EMC（Electromagnetic Compatibility）property for WLAN（Wireless Local Area Network）operations are demonstrated in this thesis. With the EMC property, the proposed antennas are suitable to be applied as internal antennas in mobile communication devices, such as the smart phones or PDA（Personal Digital Assistant）phones. With the antenna ground portion functioning as a new ground structure, the EM fringing fields in the surrounding region of the proposed antennas are greatly reduced to be negligible. When the possible RF shielding metal case or other electronic components are placed close to the proposed antennas, the antenna performances are almost unaffected. In other words, the isolation distance between the antenna and the nearby components will be no long required. This can lead to a compact integration of the proposed antennas with the nearby components in mobile communication devices. Details of the measured and simulated results of the proposed EMC chip antennas are presented and discussed.
