WIRELESS MIC ANTENNA PROVIDED WITH MEANDER LOOP STRUCTURE

摘要

A wireless microphone antenna having a meander loop structure is provided to satisfy a requested bandwidth by having an omni-directional characteristic with a small size. A wireless microphone antenna having a meander loop structure includes a board(100), and a loop element(200). The board has a base unit and a feeding unit which is protrusively expanded from the center of an upper part of the base unit. The loop element is composed of a plurality of pulse type lines. The loop element forms a meander loop which wraps a circumference of the feeding unit with a rectangular shape or a circular shape. An end of the meander loop is coupled to the feeding unit through the feeding line. The feeding unit forms a conductive feeding line on a front plane, and is extended to a lower part of a front plane of the base unit. The base unit forms a first ground plane which is far from both sides of the feeding line, on a front plane.
