MONOPOLE ANTENNA HAVING A MATCHING FUCTION

摘要

A monopole antenna having a matching function is provided to improve performance of the antenna by expanding a bandwidth of an operation frequency. A monopole antenna having a matching function includes a ground(5) and a radiator(10). The radiator has a plurality of band-shaped first radiation units(20) of and at least one second radiation unit(15). The plurality of band-shaped first radiation units are connected to a side of the ground in a direction perpendicular to the ground. The at least one second radiation unit is formed by being bent from an end of the first radiation unit at least one time. The first radiation unit includes a first radiation line(21) and a pair of second radiation lines(22). The first radiation line is connected to the ground. The pair of second radiation lines is arranged at both sides of the first radiation line at a predetermined interval to be spaced apart from the ground.
