Problems solved by technology

However, when the PIFA antenna is applied to increasingly miniaturized mobile phones, its high frequency part (1800MHz, 1900MHz) often encounters the problem of insufficient bandwidth
And because 1800MHz is a frequency multiplier of 900MHz, it is easy to cause mutual interference due to the even harmonics generated by 900MHz during signal transmission, so how to design one can effectively avoid frequency multiplication interference and have better transmission power. A multi-frequency antenna device with a large bandwidth is a direction that needs to be worked on urgently

Abstract

The antenna unit is applied to electromagnetic wave transceiver. The wave transceiver includes a case and a circuit board. The case defines an accommodation space. Installed on the accommodation space, the circuit board possesses a feedthrough port for first signal, a feedthrough port for second signal and a grounding terminal. The antenna unit includes a base plate, a first radiant element, a second radiant element and a grounding wire. The first radiant element arranged on base plate possesses a wrapped polygonal line and at least a connection line. One end of wrapped polygonal line is suitable to conduct to the feedthrough port for first signal on the circuit board. The second radiant element arranged on base plate is setup on side of the first radiant element with an interval. One end of the second radiant element is suitable to conduct to the feedthrough port for second signal. The grounding wire arranged on base plate is connected to grounding terminal on circuit board.

Description

technical field [0001] The invention relates to a multi-frequency antenna device, in particular to a hidden multi-frequency antenna device. Background technique [0002] Today, with the advancement of communication technology, communication systems have more and more stringent requirements on their weight, volume, cost, performance and ease of assembly. Among them, for communication systems, the antenna device used to transmit and receive signals Even more so. General mobile phone antennas can be roughly divided into two types: exposed and hidden: common exposed antennas such as helical antennas (Helical Antenna), and planar inverted F antennas (Planar Inverted F Antenna, hereinafter referred to as PIFA antennas) are Hidden antennas are widely used at present. [0003] In the current general mobile phones, in order to allow users to receive messages more conveniently and clearly, they will not be unable to communicate because the mobile phone system manufacturers use diffe...
