The miniaturization of electronic devices has facilitated increasing interest in new applications of wireless communication. In this paper, a new miniature microstrip fed boomerang-shaped patch antenna has been proposed and designed for a wireless sensor network (WSN) application. In this design, the proposed antenna possesses a wide bandwidth by loading of a boomerang-shaped patch; with a 50 $\mathrm{\Omega }$ microstrip feed line and a partial ground plane. A one-step staircase slot is embedded in the ground plane to enhance the impedance matching over a wide frequency range. The antenna occupies a small size of 10 × 12 mm², or 1.2 cm². The simulated results are verified with measured results. The measured result shows that the achievable bandwidth of 69% (8.48–17.45 GHz). The antenna possesses stable radiation patterns and acceptable gain. The proposed low profile antenna is suitable to integrate with sensors for wireless sensor network in X-band and Ku band applications.

电子设备的小型化促进了人们对无线通信的新应用的日益增长的兴趣。本文提出了一种新型的微型微带馈电回旋镖形贴片天线，并设计用于无线传感器网络（WSN）应用。在这种设计中，建议的天线通过加载回旋镖形贴片而具有较宽的带宽；与50$\mathrm{\Omega }$微带馈线和部分接地平面。接地层中嵌入了一个阶梯式阶梯槽，可在较宽的频率范围内增强阻抗匹配。天线的尺寸很小，为10×12 mm ²或1.2 cm ²。模拟结果与测量结果进行了验证。测量结果表明，可实现的带宽为69％（8.48–17.45 GHz）。该天线具有稳定的辐射方向图和可接受的增益。所提出的薄型天线适合与X波段和Ku波段应用中的无线传感器网络的传感器集成。
