本文提出了一种用于雷达探测器的阿基米德螺旋天线的实现方法，该雷达探测器用于探测2-18 GHz频率范围内的雷达信号传输。本研究设计了一种适用于上述信息频段的天线。该天线覆盖的多个频段包括S波段（2-4 GHz）、C波段（4-8 GHz）、X波段（8-12 GHz）和Ku波段（12-18 GHz）。所设计的天线具有直径为5cm的螺旋形状。天线在Roger Duroid 5880衬底上实现，其中εr = 2.2，厚度为0.787 mm，并且对于铜包覆层为1 oz。这些螺旋天线由于平面结构和圆极化而具有超宽带特性，阻抗为188欧姆。仿真结果表明，天线的驻波比为1.1 ~ 1.27，增益范围为3 ~ 6dBi，3dB带宽为61.7 °。测量结果与模拟结果之间存在相似之处。实现的天线显示出优点，例如，与市场上现有的天线相比，VSWR <;2和高增益。
In this paper, a realization of archimedes spiral antenna for a Radar detector is presented, where this Radar detectors are used to detect Radar signal transmission within the frequency range of 2-18 GHz. In this research, an antenna was designed for the above information band. Multiple frequency bands covered by this antenna S band (2-4 GHz), C band (4-8 GHz), X band (8-12 GHz) and Ku band (12-18 GHz). The designed antenna has a shape of a spiral with a diameter of 5 cm. The antenna was implemented on a Roger Duroid 5880 substrate with εr = 2.2, thickness of 0.787 mm, and 1 oz for copper cladding. These spiral antennas have ultra wideband characteristics due to the planar structure and circular polarization with impedance of 188 Ohm. From the simulation results of the designed antenna, we obtained VSWR of 1.1 up to 1,27, a gain ranging from 3 to 6 dBi, with 3dB bandwidth of 61.7 degree. There is a similarity between the measurements and the simulation results. The realized antennas show advantages, e.g., VSWR <;2 and high gain, compared which the existing antennas in the market.
