【摘要】：設(shè)計(jì)了一種緊湊的具有三陷波特性的超寬帶天線。天線采用漸變微帶線饋電,并通過矩形加半圓的輻射單元和半圓形地板來實(shí)現(xiàn)超寬帶。通過在輻射單元上刻蝕對稱的L形槽和圓環(huán)形槽,來實(shí)現(xiàn)在WLAN/WiMAX的陷波特性;在漸變微帶饋線兩側(cè)增加對稱的C形諧振器來達(dá)到在X頻段的陷波特性。實(shí)驗(yàn)結(jié)果表明,天線在2.68~13GHz頻段內(nèi)電壓駐波比小于2,同時(shí)在3.1~3.8GHz,5~5.9GHz,7.25~7.85GHz頻段內(nèi)有陷波抑制作用,且具有良好的輻射特性。天線具有較小的幾何尺寸,僅為20mm×30mm。
[Abstract]:A compact ultra-broadband antenna with three-notch characteristics is designed. The antenna is fed by gradual microstrip line, and ultra-broadband is realized by rectangular plus semicircular radiation unit and semicircular floor. The notch characteristics of WLAN/WiMAX are realized by etching symmetric L-shaped grooves and circular grooves on the radiation element, and the notch characteristics of X-band are achieved by adding symmetrical C-shaped resonators on both sides of the gradual microstrip feeder. The experimental results show that the voltage standing wave ratio of the antenna in 2.68~13GHz band is less than 2, and at the same time, the antenna has notch suppression in the frequency band of 3.1 鹵3.8GHz, 5 鈮，
