Problems solved by technology
[0004] In the prior art, although the currently used chip antenna has greatly improved in volume compared with the traditional antenna, the overall volume is still relatively large. The reason is that the feeder of the currently used chip antenna is usually arranged on the substrate On the surface, in order to meet the bandwidth requirements of the wireless line number, it is often necessary to set up a sufficiently long feeder line, so the substrate needs to be large enough to arrange enough radiation electrodes, resulting in the overall volume of the chip antenna is still too large
Not only that, the structure of the currently used chip antenna is complicated, which is not conducive to reducing the production cost of the antenna itself

Embodiment Construction
[0040] In order to facilitate the understanding of the present invention, the present invention will be described more fully below with reference to the associated drawings. Several embodiments of the invention are shown in the drawings. However, the present invention can be embodied in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided so that the disclosure of the present invention will be thorough and complete.
[0041] It should be noted that when an element is referred to as being “fixed on” another element, it may be directly on the other element or there may be an intervening element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or intervening elements may also be present. The terms "vertical," "horizontal," "left," "right," and similar expressions are used herein for purposes of illustration only.
[0042] Unless otherwise def...

A chip antenna according to the present invention comprises a dielectric plate, a feed electrode plate, a radiation electrode plate and a feed line, the radiation electrode plate is stacked on the top of the dielectric plate, and the feed electrode plate is arranged on the dielectric plate and connected to the bottom of the dielectric board through a number of insulated connecting columns, all the connecting columns are arranged in a queue, and a feeder board is arranged on the top of the last connecting column, so The dielectric plate is provided with a through accommodating hole at a position above the feeding plate, the feeding plate is accommodated in the accommodating hole, and is in close contact with the radiation electrode plate, and the feeding line Starting from the first connecting column, winding around each connecting column in turn, and one end of the feeding line is connected to the feeding electrode plate, and the other end of the feeding line is connected to the feeding plate connect. The chip antenna in the present invention has small volume and strong impedance matching ability.
Description
technical field [0001] The invention relates to the technical field of wireless communication, in particular to a chip antenna. Background technique [0002] With the rapid development of wireless communication technology, most electronic products (such as mobile phones, personal digital assistants, notebook computers, sensing devices, etc.) currently have the function of transmitting signals using wireless communication, and wireless communication mainly transmits and receives signals. The device is an antenna mounted on an electronic product. [0003] In order to reduce the production cost of the antenna itself and meet the design requirements of light, thin, short, and small electronic products, most of the current wireless communication electronic products use smaller chip-type antennas to replace larger traditional antennas (such as rod antenna). [0004] In the prior art, although the currently used chip antenna has greatly improved in volume compared with the tradit...
