Abstract

This paper presents a low-profile, high gain, beam-tilted continuous transverse stub (CTS) array antenna at W-band. The antenna compromises 32 radiating slots and is fed by a parallel plate waveguide (PPW) network with a linear source generator. To deflect the outgoing beam, the principle of linear array scanning is adopted to design inverted T-type structure in each stub to introduce wave path difference. PPW network allows the antenna to obtain lower profile compared to other transmission lines. The design procedure, and the antenna characterization are described. The main beam of the antenna is titled 12 degree in H-plane. The simulation and measured results show that this antenna achieves peak gain of 32.4 dB and a 12 degree beam tilt angle at 99GHz. S11 parameters of the antenna is less than -10 dB in a broadband from 96 GHz to 103 GHz. This antenna has an advantage of miniaturization over other high-gain antenna solutions. The promising performance of this proposed CTS antenna reveals the possible candidate for Millimeter wave (MMW) telecommunication applications.

w波段低轮廓波束倾斜连续横向短段阵列天线

本文提出了一种w波段低轮廓、高增益、波束倾斜连续横向存根(CTS)阵列天线。该天线包含32个辐射槽，并由带线性源发生器的平行板波导(PPW)网络馈电。为了使出射光束偏转，采用线阵扫描原理，在每个存根处设计倒t型结构，引入波程差。与其他传输线相比，PPW网络允许天线获得更低的轮廓。介绍了天线的设计过程和天线特性。天线的主波束在h平面上呈12度角。仿真和实测结果表明，该天线在99GHz时峰值增益为32.4 dB，波束倾角为12度。在96 GHz ~ 103 GHz宽带范围内，天线的S11参数小于- 10db。与其他高增益天线解决方案相比，该天线具有小型化的优点。该CTS天线的良好性能为毫米波通信应用提供了可能的候选者。

期刊介绍： The ACES Journal is devoted to the exchange of information in computational electromagnetics, to the advancement of the state of the art, and to the promotion of related technical activities. A primary objective of the information exchange is the elimination of the need to "re-invent the wheel" to solve a previously solved computational problem in electrical engineering, physics, or related fields of study. The ACES Journal welcomes original, previously unpublished papers, relating to applied computational electromagnetics. All papers are refereed. A unique feature of ACES Journal is the publication of unsuccessful efforts in applied computational electromagnetics. Publication of such material provides a means to discuss problem areas in electromagnetic modeling. Manuscripts representing an unsuccessful application or negative result in computational electromagnetics is considered for publication only if a reasonable expectation of success (and a reasonable effort) are reflected. The technical activities promoted by this publication include code validation, performance analysis, and input/output standardization; code or technique optimization and error minimization; innovations in solution technique or in data input/output; identification of new applications for electromagnetics modeling codes and techniques; integration of computational electromagnetics techniques with new computer architectures; and correlation of computational parameters with physical mechanisms.
