Embodiment

[0040] In order to verify the effectiveness of the scheme of the present invention, the following experiments were carried out.

[0041] refer to figure 1 , a SIW-based 5G millimeter wave filter antenna, including a first layer structure 13 arranged on the upper surface of the first layer dielectric substrate Sub1, including three metal patches 1, 2, 3 with a certain distance, these three metal patches The patch is an integral part of the ME patch dipole antenna. Each of the metal patches 1 and 3 has two arc corners, which can improve the performance of the patch. The second layer structure 14 disposed between the lower surface of the first dielectric substrate Sub1 and the upper surface of the second dielectric substrate Sub2 includes a pair of symmetrical radiation grooves 4 . The connection with the patch antenna of the first layer structure can be realized through the pair of radiation slots. The third layer structure 15 arranged between the lower surface of the second ...

Abstract

The invention provides a 5G millimeter wave filtering antenna based on SIW. A radiation substrate integrated cavity SIC resonator and a non-radiation SIC resonator loaded by an ME dipole antenna are adopted to realize a Chebyshev filtering function of a coupled resonator; a dual-slot feed ME radiation dipole antenna is adopted, and a non-radiation SIC resonator is used as a support to control a radiation pattern and corresponding coupling of a filtering antenna. The antenna has the advantages of high performance, flat gain, strong filtering function, small size and the like, and can be applied to the field of 5G millimeter waves.

Description

technical field [0001] The invention relates to microwave technology, in particular to a 5G millimeter wave filter antenna based on a substrate integrated waveguide (SIW). Background technique [0002] Due to the rapid development of wireless communication systems and manufacturing technologies, many researchers and some of the world's leading companies are studying ways to design various EM component configurations, hoping to achieve high performance, multi-purpose, low loss, and compactness. As an emerging technology category, 5G mobile communication systems pave the way for the growing subscription demand in the mobile phone market and many connection-based services. Examples include unprecedented high data rates and channel capacities with low latency for IoT and machine-to-machine (M2M) applications. However, efficient utilization of radio frequency power and spectrum and reduction in overall size are still significant issues to be overcome in high-quality communicatio...
