Embodiment Construction

[0019] The present invention will be further described in detail below through specific embodiments in conjunction with the accompanying drawings.

[0020] The main inventive idea of ​​the present invention is: use the top layer metal in the CMOS process, generally aluminum or copper, as the metal material, adopt a folded structure made of mirror surfaces, and use the width and thickness of the metal to achieve frequency matching and matching under the corresponding bandwidth. Impedance matching; at the same time, using silicon-based substrates and deposited silicon dioxide to achieve dielectric isolation; setting the bottom metal in the CMOS process as the ground terminal, changing the duty cycle of the metal layer between the top metal and the bottom metal to adjust and improve the radiation pattern of the antenna.

[0021] The antenna shown in the present invention is as attached figure 2 As shown, the main structure of the antenna is made of aluminum, its conductivity co...

Abstract

The invention (an 'on-chip integrated silicon-based folding antenna') discloses an on-chip integrated antenna. The antenna is applied to an integrated ultra-wideband antenna of an integrated circuit system. The on-chip integrated silicon-based folding antenna is mainly characterized in that the selected materials include a silicon-based substrate and intermediate-layer and top-layer aluminum metal deposited on the silicon-based substrate. The main planar structures include a folding structure, and a metal grid structure used for adjusting the radiation performance of the antenna. The antenna of the invention can be completely compatible with a traditional CMOS planar technology. Transmission and reception of wideband signals within the bandwidth of 6-8GHz can be realized. Impedance matching between a transmitting end and a power amplifier and between a receiving end and a low-noise amplifier is realized, namely, 50ohm. Certain transmission efficiency and better transmission loss characteristic are achieved. The radiation direction pattern of the antenna can be adjusted to a certain extent. The antenna of the system can be applicable to on-chip antennas applied to different systems to a certain extent.

Description

technical field [0001] The present invention relates to silicon-based integrable antennas, in particular, ultra-wideband antennas that can be integrated on-chip with integrated circuits (ICs). Background technique [0002] The on-chip antenna mainly realizes the signal transmission and reception of the wireless transmission system in the integrated circuit. Its realization function is similar to that of a traditional antenna. It needs to realize the transmission and reception of electromagnetic waves. At the same time, it needs to complete the impedance matching between the transmitting end and the power amplifier and the impedance matching between the receiving end and the low noise amplifier. Its key parameters are the operating bandwidth during transmission and reception, that is, the operating frequency range; and the energy loss during wireless transmission. [0003] The main feature of the on-chip antenna is to realize the compatibility with the existing CMOS process,...
