摘要

与常规TCDA保持了TCDA的特性而不使单元弯曲不同，本文首先提出了一种新颖的圆柱形TCDA，其单元沿周向采用可接合设计连接。采用圆柱设计和顺序旋转馈电技术，TCDA在整个频段内的轴向比小于3 dB，具有良好的圆极化特性。同时，提出的TCDA仍然具有10.3:1带宽（2.6-26.7 GHz）的超宽带特性和有源VSWR <；3、宽扫描范围±70°。此外，制作并测量了一个18单元圆柱形TCDA原型，验证了我们的设计。在测量和模拟的辐射图之间得到了很好的一致性。由于其柱面设计、CP、超宽带宽和广角扫描等特点，使TCDA的应用领域从微波扩展到毫米波。

A cylindrical tightly coupled dipole array (TCDA) with circular polarization

Different from the regular TCDA, which maintains the characteristics of TCDA without bending the element, this paper first presents a novel cylindrical TCDA, of which the elements are connected by joinable design along the circumferential direction. By utilizing the cylindrical design and sequentially rotated feed technique, the axial ratio (AR) of the proposed TCDA over the whole band is less than 3 dB, showing a great circular polarization (CP) characteristic. Meanwhile, the proposed TCDA remains an ultrawideband property with 10.3:1 bandwidth (2.6–26.7 GHz) and an active VSWR < 3, within a wide-scanning range of ± 70°. Moreover, an 18-element cylindrical TCDA prototype is fabricated and measured, validating our design. Good agreement is obtained between the measured and simulated radiation patterns. Due to the distinctive features of cylindrical design, CP, ultra-wide bandwidth, and wide-angle scanning, the proposed TCDA expands the application fields operated in microwave to millimeter-wave.
