Abstract

The invention discloses an antenna with multi-bands, comprising a ground plane which defines a plurality of different band sections, and a first radiation element arranged on the ground plane, wherein the first radiation element comprises a first bending section, a second bending section, and a second radiation element which extends from the second bending section of the first radiation element, and a front end and a tail end of the second radiation element are both provided with a flange. In one embodiment, the antenna of the invention is connected with an interface port of an electronic apparatus, and the different band sections arranged on the ground plane can be adjusted in dependence on distances between the band sections and the interface port in such a way that the antenna can correct frequency response to reach an applicable band, with an adjustable bandwidth of 330 MHz.

Description

technical field [0001] The present invention relates to an antenna design, in particular to a multi-frequency antenna design. Background technique [0002] As is well known, an antenna is a transducer designed to transmit or receive electromagnetic waves. In other words, the antenna converts electromagnetic waves into electrical current and vice versa. Broadly speaking, antennas typically operate in the air and outer space, can also operate underwater, and even in soil and rock at certain frequencies. [0003] Based on the above, in the past few years, because the required size of the microstrip antenna is extremely thin (about 0.01-0.05 free-space wave length), it is the most suitable for the micro-electromechanical process compared to other types of antennas, and has the advantages of small size , light weight, thin thickness and low manufacturing cost, due to these attractive features, it is used in many military, space shuttle, satellite and commercial purposes.
