Description

Technical Field

[0002] GNSS antenna is mainly used as a transmitting antenna in the same-frequency repeater system. The antenna consists of a radome, a microstrip radiator, a base plate and a high-frequency output socket. It is used as a receiving antenna in GPS navigation and positioning systems.

[0003] Existing GNSS antennas are generally installed inside the bottom shell when in use, and most of them are fixed and connected by screws.

If the screws become loose later, the GNSS antenna will shake and malfunction due to the lack of a limiting structure. For this reason, we propose a miniaturized GNSS antenna. Utility Model Content
