摘要

研究了一种电容式cpw馈电多波段缝隙天线。对于10db分数带宽，在2.49 GHz、3.57 GHz和5.25 GHz中心频率下，天线的增益分别为12.9%、2.52%和5.33%。通过使用多个凸槽，可以实现多个工作频带，设计自由度高。三种工作频率分别用于WLAN2400/5200和WiMAX应用。天线尺寸为70 mm (L) × 40 mm (W) × 0.8 mm (H)，实现了近全向的H面辐射方向图。

CPW-fed tri-band slot antenna with impedance matching stub

A capacitively CPW-fed multiband slot antenna is investigated in this paper. For 10-dB fractional bandwidth, the proposed antenna obtains 12.9%, 2.52%, and 5.33% at the center frequencies of 2.49 GHz, 3.57 GHz and 5.25 GHz, respectively. By using multiple protruded slots, one can achieve multiple operation bands with high design freedom. The three operation frequencies are for WLAN2400/5200 and WiMAX application. The antenna size is 70 mm (L) × 40 mm (W) × 0.8 mm (H). The proposed antenna achieves a near omnidirectional H-plane radiation patterns.
