本論文主要在探討一個新型態多頻帶具槽孔的非對稱三角形天線在筆記型電腦上的應用,天線的構成是由一個三角形的單極天線以及一個槽孔。
本文使用折疊的方式將非對稱三角形輻射體縮小,並在其上切一道槽孔以增加低頻的阻抗頻寬及使高頻的阻抗匹更好。
本論文所提出的天線有效的操作範圍是在CDMA (824-894 MHz)、GSM (880-960MHz)、 DCS (1710-1880 MHz)、PCS (1850-1990 MHz) 和 WCDMA (1920-2170 MHz)取VSWR的範圍在2.5以下,詳細的設計尺寸以及各項參數的變化影響在文章中都會說明。
A novel multi-band asymmetric triangular monopole antenna (ATMA) with a slot for Laptop applications is explored. The antenna consists of a driven triangular monopole and slot strips.
The asymmetric triangular patch is folded to reduce the size of the antenna, and a cut was employed to increase the bandwidth of the lower operating band and to improve impedance matching of upper operating band.
The proposed antenna operates effectively in the CDMA (824-894 MHz), GSM (880-960 MHz), DCS (1710-1880 MHz), PCS (1850-1990 MHz) and WCDMA (1920-2170 MHz) within VSWR of 2.5:1. Detail criteria with respect to geometrical parameter variation are given to expedite design process.
