Summary:碩士 === 國立高雄科技大學 === 光電與通訊工程研究所 === 107 === In this study, the multi-antenna designs are proposed for full-screen laptop. Due to the impact of the full-screen development of mobile phones in recent years, notebook computers have begun to adopt this design, but this design will compress the space of the antenna, so three kinds of notebook antenna design with full-screen applications are proposed. Features include multi-frequency operation characteristics, All the antenna have operating bands at LTE middle band (1710~2690 MHz); n78 (3300~3600 MHz); n79 (4800~5000 MHz); WLAN 2.4GHz (2400~2480 MHz) WLAN 5GHz (5150~5850 MHz), It can supports WLAN bands and combined with future 5G communication bands, while retaining the original LTE band demand. An inverted F-type antenna for laptop computer with equivalent capacitance structure in proposed. Antenna design on the side border frame of the keyboard. The characteristics of the multipath resonate with multiple modes and are fine-tuned with an equivalent capacitance structure. The antenna operation bands cover WLAN 2.4/5GHz, n78 and n79. The second design is a hinge slot antenna for laptop computer excitation by monopole antenna. The structure of the application is the same as the previous one. The antenna design space is located at the Rotating shaft of the screen and keyboard (Hinge). The monopole antenna is used to excite the closed slot. The operation bands cover LTE middle band and WLAN 5GHz. The third design is a inverted F-type antenna for laptop computer with isolation mechanism. It is designed at the edge of the keyboard system ground, and the inverted F-type antenna is excited to generate dual frequency resonance. The operation bands cover WLAN 2.4/5GHz, and is connected by neutralization line between the two antennas to optimize the isolation. Finally, the relevant parameters of the MIMO system are discussed for the antenna proposed in this paper, so as to find the best placement method to optimize the performance of the MIMO system.
