【摘要】：設(shè)計(jì)了一種16×8脊波導(dǎo)縫隙陣列天線,線陣陣面分成兩個(gè)子陣,饋電采用同軸饋電與耦合縫隙饋電結(jié)合的兩級(jí)饋電方式,輻射縫隙分布為泰勒分布。天線設(shè)計(jì)采用近場(chǎng)診斷方法和阻抗過載技術(shù)進(jìn)行優(yōu)化。天線實(shí)物加工測(cè)試結(jié)果表明,天線在X頻段駐波帶寬(VSWR≤1.5)為7.3%,最低副瓣達(dá)到-25.8 d B,副瓣電平帶寬(SLL≤-19 d B)為6.2%。與已有文獻(xiàn)相比,該天線同時(shí)具備阻抗寬帶特性和低副瓣寬帶特性,工作頻帶內(nèi)具有增益均大于16 d Bi的高增益特性。
[Abstract]:A 16 脳 8 ridge waveguide slot array antenna is designed. The linear array plane is divided into two subarrays. The two stage feeding mode is coaxial feed and coupling slot feed. The radiation slot distribution is Taylor distribution. The antenna design is optimized by using near field diagnosis method and impedance overload technique. The experimental results of antenna processing show that the standing wave bandwidth (VSWR 鈮，
