Dual‐polarised end‐fire antenna based on the high‐order mode of spoof surface plasmon polaritons

IET Microwaves, Antennas & Propagation
A planar antenna with dual‐linearly polarised end‐fire radiation is proposed. A tapered double‐sided symmetrical spoof surface plasmon polariton (SSPP) transmission line (TL) with tilted unit cells is proposed.

A Broadband Multipole Method for Accelerated Mutual Coupling Analysis of Large Irregular Arrays Including Rotated Antennas

We present a numerical method for the analysis of mutual coupling (MC) effects in large, dense, and irregular arrays with identical antennas. Building on the method-of-moments (MoM), our technique uses a macro-basis function (MBF) approach for rapid ...

Analysis and Design of Broadband Slot Spiral Antennas

, 2007
在本論文中，我們設計一寬頻螺旋型天線，利用理論分析、HFSS 模擬及實驗設計驗證其寬頻特性。我們利用寬頻微帶線和槽帶轉接器設計外部饋入輸入網路並利用寬頻電阻性阻抗轉換器和反射空腔，以改善螺旋型天線的輻射特性。實驗證明此天線可達到 2.2 到 4 GHz 的阻抗頻寬及輻射頻寬，可符合寬頻系統之需求。In this thesis, broadband and multiband Archimedean slot spiral antennas are analyzed and designed. A new
