Abstract

A chip antenna comprises a substrate chip, a first patch antenna and a second patch antenna, wherein the first patch antenna and the second patch antenna are arranged above the substrate chip, an upper surface of the first patch antenna is attached onto a lower surface of the second patch antenna, the first patch antenna comprises a metal microstrip feeder, a first dielectric layer and a first conductive layer which are sequentially arranged from top to bottom, the second patch antenna comprises a metal radiation patch and a second dielectric layer which are sequentially arranged from top to bottom, a bottom filler layer is arranged between the substrate chip and the first patch antenna, the substrate chip and the first patch antenna are electrically connected, a signal emission assembly is arranged on an upper surface of the metal radiation patch and comprises a signal emission part and a plurality of micro vertical posts, the signal emission part is used for emitting a signal towardsa circumferential direction, and the plurality of micro vertical posts are uniformly arranged in a way that the signal emission part is encircled. With the chip antenna proposed by the invention, thesignal radiation angle is greatly expanded, and the signal emission omnidirectivity is improved.

Description

Technical field[0001]The present invention relates to the field of chip technology, in particular to a chip antenna and electronic equipment using the chip antenna.Background technique[0002]In recent years, with the rapid development of wireless communication systems, the requirements for antennas have become higher and higher. Traditional whip antennas and helical antennas have been gradually replaced by built-in small antennas because they cannot meet actual needs.[0003]Currently, dielectric chip antennas are being produced and used on a large scale due to their small size, light weight, and stable electrical characteristics. Moreover, the production cost is relatively low, and it has a good economic advantage in industrial production, so it is produced and applied on a large scale.[0004]However, when the existing dielectric chip antennas actually transmit signals, their omnidirectional performance is not satisfactory. That is, when the signal is transmitted, the signal cannot be ...
