本文提出了一種L/S頻段的圓極化雙頻單貼片天線。通過(guò)在矩形貼片采用單貼片的微擾法來(lái)實(shí)現(xiàn)雙頻，即通過(guò)單一貼片激勵(lì)兩個(gè)主要的橫磁波模式實(shí)現(xiàn)雙頻，這里主要是TM10和TM30模；采用簡(jiǎn)單的單同軸饋電實(shí)現(xiàn)圓極化，尺寸小結(jié)構(gòu)緊湊，實(shí)現(xiàn)阻抗帶寬與３ｄＢ軸比帶寬的匹配。實(shí)驗(yàn)結(jié)果表明天線的反射系數(shù)在兩個(gè)頻率f1=1.54GHz，f2=2.98GHz處都小于-15dB，而增益在1dB左右，3dB軸比帶寬大于15MHz，交叉極化小于-20dB，滿(mǎn)足指標(biāo)要求，可應(yīng)用于有LNA的弱信號(hào)系統(tǒng)。實(shí)測(cè)與仿真結(jié)果基本一致。
