應用在四頻段衛星訊號接收指叉式天線,分別設計四片天線操作頻率150、400、960、2200MHz,天線架構為一端電感性饋入其餘兩端接地,並利用天線的指叉式電容控制中心頻率,調整饋入位置來阻抗匹配,各頻段天線位置的擺放是經過參數分析後最佳的調整結果,接地面尺寸為600mm*150mm*0.8mm的FR4板,150MHz天線尺寸為72 mm*38 mm*0.8 mm,400MHz天線尺寸為24 mm*23 mm*0.8 mm,960MHz天線尺寸為13.5 mm*10 mm*0.8 mm,2200MHz天線尺寸為6 mm*6 mm*0.8 mm,此篇論文提供了不同的小型化衛星訊號接收天線設計,
LTE頻段的天線設計分為高頻天線與低頻天線,高頻天線利用電容性饋入來製造寬頻效果,使其-6dB頻寬覆蓋1710 ~ 2690MHz (GSM1800/GSM1900/UMTS/LTE2300/ LTE2500),而低頻天線是用電感性饋入,並外加可變電容的方式達到可調頻率的效果,使其直流偏壓在0.52V時,-6dB頻寬包含698~787MHz,調整直流偏壓到3.62V時,-6dB頻寬包含824~960MHz,接地面尺寸為170mm*240mm* 0.8mm,高頻天線尺寸為19mm*18mm*0.8mm的FR4板,低頻天線尺寸為9mm* 10mm*0.8mm的FR4板,此篇論文提供不同的LTE天線設計方法。

In the thesis, interdigital-capacitor antennas are applied to the four-band satellite signal receivers. Antenna operation frequencies are 150、400、960 and 2200 MHz. The structure of antenna is composed of one inductive feeding and two shorts to ground. Interdigital-capacitor is used to adjust antenna central frequency. Changing input position can achieve impedance matching. Through parametric analysis, the optimal design can be achieved. The size of ground plane (FR4 substrate) is of 600mm*150mm*0.8mm. Antenna sizes are of 72 mm*38 mm*0.8 mm at 150MHz, 24 mm*23 mm*0.8 mm at 400MHz, 13.5 mm*10 mm*0.8 mm at 960MHz, and 6 mm*6 mm*0.8 mm at 2200MHz. This paper provides a different way to design antenna for satellite signal receiver.
Antenna design for eight-band LTE/GSM/UMTS devices is also presented. The highband antenna uses capacitive feeding to enhance bandwidth. The coupling feed leads to a wide operating band to cover the frequency range of 1710–2690 MHz for the GSM1800/1900 /UMTS/LTE2300/LTE2500 operation. The lowband antenna uses inductive feeding and a varactor to make the antenna reconfigurable. With the DC bias of 0.52 volt,the antenna covers the frequency range of 698-787 MHz. With the DC bias of 3.62 volt,the antenna covers the frequency range of 824-960 MHz. The ground size is of 170mm* 240mm* 0.8mm.The antenna size is of 19mm*18mm*0.8mm at LTE700/GSM850/GSM900,and 9mm* 10mm*0.8mm at GSM1800/GSM1900/UMTS/ LTE2300/ LTE2500.
