Abstract

The invention relates to the technical field of microstrip antennas, in particular to a low-profile GSM-LTE coplanar directional antenna. The low-profile GSM-LTE coplanar directional antenna comprises a metal reflecting plate, an LTE radiating element patch, an LTE radiating element parasitic patch, a GSM radiating element patch, an LTE radiating element feed structure and a GSM radiating element feed structure. According to the low-profile GSM-LTE coplanar directional antenna, the LTE radiating element patch, the LTE radiating element parasitic patch and the GSM radiating element patch are arranged on the metal reflecting plate in a coplanar manner. The low-profile GSM-LTE coplanar directional antenna is in directional radiation, simultaneously supports a GSM band and an LTE band, has a low profile and a simple structure when obtaining a wide working band, is directly fed by a coaxial feeder line; a complicated feed network is omitted; and design and installation are facilitated.

Description

technical field [0001] The invention relates to the technical field of microstrip antennas, in particular to a low-profile GSM and LTE coplanar directional antenna. Background technique [0002] With the diversified development of mobile communication services, multi-mode operation of antennas has become an ideal solution for multi-network access in consideration of compatibility, and there are more and more situations where systems or terminals work in multiple modes. Therefore, it has become a current research hotspot to research and design a wide-band, low-profile, and miniaturized antenna that can realize multiple antennas built in a limited space. Broadband or multi-band antennas and multi-antenna technologies have been widely used in current mobile terminals (mobile phones) to meet the needs of multi-mode work. The antennas are basically omnidirectional radiation. Designing such antennas in a very small space is currently mainly The concern is still the performance of...
