Problems solved by technology

[0009] This method will greatly increase the overall area of ​​the chip, which cannot meet the compact design requirements of today's wireless devices; moreover, since the antenna and the chip are on the same horizontal plane, no matter whether the antenna is omnidirectional or unidirectional, it will inevitably cause a certain degree of damage to the chip. interference

Embodiment Construction

[0028] The invention adopts the microstrip antenna to realize the integration of the antenna and the circuit chip. This method only increases the height of the original circuit chip, reduces the area of ​​the chip, and effectively reduces the interference of the antenna to the chip circuit.

[0029] With the popularity of mobile wireless devices, microstrip antennas have been applied due to their convenient processing, beautiful appearance, and the characteristics of radiation to the human body; moreover, the performance of microstrip antennas has been improved through various technical means, such as improving the area and shape of the Patch. To improve the bandwidth and radiation efficiency of the antenna, therefore, the microstrip antenna has been used more and more. For the principle and application of the microstrip antenna, please refer to the book "Microstrip Antenna" published by People's Posts and Telecommunications Press and translated by Liang Lianzhuo of Tsinghua Un...

Abstract

The invention discloses a wireless chip, which includes a circuit layer, a micro-band antenna equipped above the circuit layer and a wave-absorbing body arranged between the circuit layer and the micro-band antenna. The micro-band antenna is equipped above the circuit layer and separates circuit and an antenna by the wave-absorbing body capable of absorbing energy, a metallic film in the micro-band antenna not only is used as radio frequency field of the antenna, but also screens disturbance, thereby effectively resolving circuit disturbance problem due to the antenna; by selecting medium with appropriate dielectric constant, height of the chip does not overmuch increase, so that the chip and wireless device using the chip are cabinet. Synchronously, the invention also provides a wireless device containing the wireless chip.

Description

technical field [0001] The present invention relates to the technical field of antennas, in particular to a chip integrated with antenna functions and a wireless device using the chip integrated with antenna functions. Background technique [0002] Antenna is an essential part of wireless equipment and usually exists as a separate device. Because the built-in antenna has the characteristics of convenient feed point, light weight, low price, good mobility and low radiation to the human body, the built-in antenna has been rapidly developed and applied in recent years. More and more mobile wireless devices work with built-in antennas, such as wireless local area network client wireless network cards, mobile phones, personal digital assistants (Personal Digital Assistant, PDA) devices and receivers in the Global Positioning System (Global Positioning System, GPS), etc. . [0003] Two typical implementation schemes of existing built-in antennas are introduced below: [0004] (...
