摘要：
This paper proposes a novel low-profile monopole mobile phone antenna capable of GSM, DCS, PCS, UMTS, and WLAN five-band operation. The proposed antenna is designed on an FR4 substrate and fed by a 50W microstrip line. Produced in this way, the antenna can be easily constructed by folding a planar meandered patch into a rectangular-tube-like structure. By using the antenna's quarter wavelength resonant mode, two operation bands centered at 900 and 2100 MHz are obtained. The impedance bandwidth, which covers 900, 1800, 1900, 2000 and 2450 MHz operating bands is achieved by adjusting antenna parameters. The proposed antenna having a compact size of 50×70×0.8 mm³, which consists of a radiation portion (50×13 mm²) and a ground plane (50×55 mm²), is suitable for placing in mobile handsets. Both the antenna design and experimental results are presented and discussed.
