A Small Size High Gain Antenna

Abstract

The invention discloses a small-sized high-gain antenna, which includes an insulating dielectric board, a U-shaped reflective surface printed on the insulating dielectric board by circuit board printing technology, two triangular metal radiation arms, and two narrow metal strips , parallel double-wire feed strip and coplanar waveguide feed structure, the bottom corners of the two triangular metal radiation arms that are relatively close to each other are connected to one end of the vertical parallel double-wire feed strip, and the two triangular metal radiation arms The top corners of the arms are respectively connected to the long metal strips arranged horizontally, the short metal strips are arranged in parallel above the long metal strips, the other end of the parallel double-wire feed strips is connected to the coplanar waveguide feed structure, and the coplanar waveguide The conductive grounds on both sides extend to both sides in a horizontal inverted L shape and work together to form a U-shaped reflective surface. The invention has a small overall size and a compact feeding method, which is beneficial to realize high integration of multiple antennas, and can be flexibly hidden inside the product, thereby realizing beautiful ID design and good signal coverage.

Description

technical field [0001] The invention belongs to the technical field of wireless communication and intelligent networking antennas, and in particular relates to a small-sized high-gain antenna. Background technique [0002] With the rapid development of the Internet of Things and smart cloud technology, smart home and wireless network access devices continue to evolve toward miniaturization, high performance, and broadband, and devices are becoming more and more sensitive to antenna size, structure, and integration complexity. With the continuous deepening of urbanization, family scenes are becoming more and more complex, and the large attenuation of concrete walls and wireless interference between neighbors are gradually becoming prominent. The traditional omnidirectional small antenna is particularly weak in solving the problem of weak signal and avoiding interference in the wall-penetrating environment. In order to solve the above problems, the present invention designs a...
