Problems solved by technology

With the rapid development of the wireless communication industry, mobile phones and PHS have been endowed with more functions (such as Bluetooth, GPS, dual-mode and UWB, etc.), which means that more and more antennas must be integrated in mobile phones and PHS , at the same time, consumers require multi-function converged mobile phones and PHS to be thinner and more reliable. These two trends put forward higher requirements for mobile phone antennas: antenna embedding and miniaturization, etc., but most of the existing The mobile phone antenna is bulky and difficult to debug and install

Embodiment 1

[0017] Embodiment 1: As shown in Figures 1 and 2, the shaded part of the oblique line is the part coated with conductive metal material, which can be Ag, Cu and other materials, and is formed by plane printing technology; this embodiment involves a multi-layer ceramic antenna ,include:

[0018] A laminated body, comprising four layers 101, 102, 103, 104 of sheet ceramic dielectric layers laminated together along the lamination direction by low temperature co-fired ceramic (LTCC) technology;

[0019] The spiral conductor includes six conductors coated with conductive metal on the sheet ceramic dielectric layer 102, which are the L-shaped conductor 102a at the signal feeding end, the L-shaped conductor 102f at the transmitting and receiving end, and the strip conductors 102b and 102c in the middle. 102d, 102e; the sheet ceramic dielectric layer 103 is coated with conductive metal to form 5 strip conductors, 103a, 103b, 103c, 103d, 103e; the ten external electrodes are side elect...

Abstract

The invention discloses a multilayered ceramics antenna, which includes: cascade body, including the multi parcel shape ceramics medium layer cascaded together along the cascade dirtection; spirality conductor, including the strip, the L conductor design which set in the each cascade body; the multi electrode which set on the cascade body side surface; the outer electrode, which set on the two terminal surfaces of the cascade body; signal infan marking, which set on the position of cascade body surface near feeding end. This invention beneficial effect: the invention through set the spiralityconductor on the LTCC (low temperature altogether burns ceramics) the laminated ceramics medium layer, has solved the descend generation mobile and small mobile design difficult problem which brings because of the design space more and more narrowness.

Description

technical field [0001] The invention relates to an antenna, in particular to a multi-layer ceramic antenna used in the field of microwave communication. Background technique [0002] The antenna undoubtedly has a very important position in the radio frequency front end of the mobile phone, and is an important component for transmitting and receiving signals. With the rapid development of the wireless communication industry, mobile phones and PHS are given more functions (such as Bluetooth, GPS, dual-mode and UWB, etc.), which means that more and more antennas must be integrated in mobile phones and PHS , At the same time, consumers require multi-functional aggregated mobile phones and PHS to be thinner and more reliable, so two trends have put forward higher requirements for mobile phone antennas: antenna embedded and miniaturized, etc., but most of the existing Mobile phone antennas are bulky and difficult to debug and install. ...
