ABSTRACT

In this study, a novel wideband slant-polarized antenna consisting of a double-ridged horn antenna and a slant polarizer is proposed. The designed slant polarizer is placed in front of the designed double-ridged horn antenna. In this way, linear polarization of the traditional double-ridged horn antenna is changed to slant polarization over a wide frequency range. This design provides a double-ridged horn antenna to be capable of transmitting and receiving whole linearly and circularly polarized signals over a wide frequency range without affecting the antenna characteristics. It also provides the ability to simultaneously radiate vertical and horizontal polarization components. The frequency range of the proposed double-ridged horn antenna with the slant polarizer is 6–18 GHz with 12 dBi typical gain. The performance of the proposed design is examined with simulations and verified with the measurements. The measurement results are in very good agreement with the simulation results.

摘要

在这项研究中，提出了一种新颖的宽带斜极化天线，该天线由双脊喇叭天线和斜极化器组成。设计的倾斜偏振器放置在设计的双脊喇叭天线的前面。这样，传统的双脊喇叭天线的线性极化在宽频率范围内变为倾斜极化。这种设计提供了一种双脊喇叭天线，能够在很宽的频率范围内发送和接收整个线性和圆极化信号，而不会影响天线特性。它还具有同时辐射垂直和水平极化分量的能力。建议的带有倾斜偏振器的双脊喇叭天线的频率范围是6–18 GHz，典型增益为12 dBi。拟议设计的性能将通过仿真进行检查，并通过测量进行验证。测量结果与仿真结果非常吻合。
