摘要

本文介绍了一种新型的140 MHz小型化单极天线。该天线适用于多种低频电磁测量系统。该设计基于曲径线，整体占地29.3厘米x 6.45厘米。与工作在140MHz的传统单极子相比，它的长度减少了46%。它还引入了13 MHz增强带宽。该设计还具有全向特性，辐射效率为80.2%，指向性为1.68 dBi。所提出的配置已经制作和测量，其中从模拟和测量中确认了低于200 MHz的工作。

Design of Low Frequency Meander Line Antenna with Efficient Size Reduction

In this paper a new 140 MHz miniaturized monopole antenna is introduced. This antenna is suitable for several low frequency electromagnetic surveying systems. The design is based on Meander Line with overall foot print of 29.3 cm x 6.45 cm. It acquires length reduction of 46% compared to traditional monopole operating at 140MHz. It also introduces 13 MHz enhanced bandwidth. The proposed design also exhibits omnidirectional characteristics with radiation efficiency of 80.2% and directivity of 1.68 dBi. The proposed configuration has been fabricated and measured, where sub 200 MHz operation is confirmed from both simulation and measurements.
