This article proposes a design and implementation of array Microstrip Patch antenna of configuration 2 × 2 at an operating frequency of 3.5 GHz. The proposed design takes a dimension of 80 mm × 92 mm × 1.6 mm with four radiating elements arranged in rectangular form with an optimized separation between the patches. All the radiating elements were connected through a corporate series network with an inset feed to have better impedance matching. The model gives an efficiency of 90.99% with a bandwidth of 510 MHz and with fractal configuration, the bandwidth further enhances to 1.12 GHz. The maximum gain measured was found as 11.01 dBi at θ = 10° and ɸ = 360° and 10.45 dBi with fractal configuration. The designed antenna is proposed to be used in RADAR which will be used in the intelligent transportation system for the detection of nearby (short-range) vehicles in the blind zone. This kind of Radar also finds its application in collision avoidance and activating airbags/break boosting and thus helping mankind by saving lives. The article gives an idea of the use of an array antenna in intelligent transportation system for better gain and efficient results.

智能交通系统应用微带阵列天线的设计与实现

本文提出了一种工作频率为 3.5 GHz 的配置为 2 × 2 的阵列微带贴片天线的设计和实现。所提出的设计采用 80 mm × 92 mm × 1.6 mm 的尺寸,四个辐射元件以矩形形式排列,贴片之间的间隔得到优化。所有辐射元件都通过带有插入式馈电的公司串联网络连接,以获得更好的阻抗匹配。该模型的效率为 90.99%,带宽为 510 MHz,采用分形配置,带宽进一步增强至 1.12 GHz。测得的最大增益在 θ = 10° 和 ɸ = 360° 时为 11.01 dBi,分形配置为 10.45 dBi。所设计的天线拟用于雷达中,该雷达将用于智能交通系统,用于检测盲区附近(短距离)车辆。这种雷达还应用于避碰和激活安全气囊/破门助推,从而通过拯救生命来帮助人类。本文提出了在智能交通系统中使用阵列天线以获得更好的增益和高效结果的想法。
