摘要

本文提出了一种微带宽带天线的紧凑型设计和结构。该天线的工作频率在1.8GHz到12GHz之间。对天线参数进行了频域分析，证明了其作为有效辐射元件的能力。仿真结果表明，该系统具有良好的宽带线性传输性能。研制了样机，测量结果吻合良好。在2ghz时最高效率为92%，最低效率为70%。在整个带宽内测得的e面和h面辐射图形状相同，最大辐射方向与贴片几何形状垂直。设计的天线具有改进的对角边接地平面、l型槽和寄生贴片为主贴片，适用于比较天线的设计。在4.7cm × 3.6cm印刷电路板(FR-4)上设计了一种低成本、紧凑尺寸的矩形贴片天线。

A compact wideband microstrip patch antenna with defected ground plane

In this paper, a compact design and construction of microstrip broadband antenna is proposed. The proposed antenna has the capability of operating between 1.8GHz to 12GHz. The antenna parameter in frequency domain analysis has been investigated to show its capability as an effective radiating element. The simulation results demonstrated good broadband linear transmission performance. A prototype is developed and measurement results are well in agreement. The highest efficiency claimed 92% at 2 GHz and minimum efficiency is 70%. The measured E-plane and H-plane radiation pattern in the entire bandwidth are identical in shape and the direction of maximum radiation is normal to the patch geometry. The designed antenna has a modified ground plane with diagonal edges, L-shaped slot and parasitic patches to main patch for the design of comp act antennas. The proposed low-cost, compact-size rectangular patch antenna on 4.7cm × 3.6cm printed circuit board (FR-4) is designed.
