Embodiment Construction

[0031] The present invention will be further described in detail below in conjunction with the accompanying drawings, so that those skilled in the art can implement it with reference to the description.

[0032] The present invention provides a dual-band Wi-Fi antenna designed based on a multi-objective evolution algorithm. For the dual-band Wi-Fi antenna, it is necessary to have a good VSWR (Voltage Standing wave ratio), and the structure of the antenna is simple and not too complicated. In conjunction with the above description, the antenna model of the present invention is an elliptical slot microstrip patch antenna, and its geometric structure and parameters are as follows figure 1 Shown: The side length of the square (FR4) substrate is L1mm, the thickness is 1.6mm, the relative dielectric constant is 4.4, and the input resistance is 50Ω. The axis ratio of the ellipse is R, and the long axis of the radiation patch on the front is d1mm. The coupling unit on the back is th...

Abstract

The invention discloses a dual-band Wi-Fi antenna designed based on a multi-objective evolution algorithm, which has a voltage standing wave ratio (VSWR) lower than 2 at 2.3-2.5GHz and 4.9-5.9GHz. The Fi antenna is modeled on an elliptical slot microstrip patch antenna. The present invention is different from the general antenna design method in the past. The VSWR of the two frequency bands is used as the target of the evolutionary algorithm alone, and a high-performance dual-band antenna is designed. The structure is simple and no complicated manufacturing process is required.

Description

technical field [0001] The present invention relates to the field of wireless technology. More specifically, the present invention relates to a dual-band Wi-Fi antenna designed based on a multi-objective evolutionary algorithm. Background technique [0002] Wireless communication plays an increasingly important role in various fields. Antenna, as the core component of wireless communication, has high standard and diversified design requirements. The previous antenna design was mainly manual, supplemented by simulation software, and relied on the experience of engineers. The design cycle was long, the efficiency was low, and it was difficult to adjust. It no longer meets the current needs. Due to its own intelligence, evolutionary algorithms show outstanding ability to solve antenna optimization problems. In addition, there have been examples of using evolutionary algorithms to design antennas before, but the goal is relatively single; and in the design of Wi-Fi antennas, m...
