Patch Antenna

Patch antennas are miniaturized antennas based on microstrip technology. They typically consist of a metal patch (radiator), a dielectric substrate, and a ground layer. Their compact structure, light weight, and ease of integration make them widely used in communications, navigation, the Internet of Things, and other fields.

Core Features

Miniaturization and Lightweight: Their planar design allows for compact size (typical sizes range from a few millimeters to tens of centimeters) and lightweight, making them suitable for installation in space-constrained devices such as smartphones, drones, and medical equipment.

Ease of Integration: They can be directly integrated with PCBs (printed circuit boards), compatible with mass production processes, and reduce overall device design complexity and cost.

Directional Radiation: Most patch antennas exhibit directional radiation, concentrating energy in a specific direction. This effectively reduces signal interference and improves communication efficiency.

Multi-band Compatibility: By optimizing patch shapes (such as rectangular, circular, or ring-shaped) or stacking them, they can support single-band or multi-band operation and are compatible with various communication standards, including GPS, WiFi, Bluetooth, and 5G. Strong Stability: Utilizing high-quality dielectric materials (such as FR4 and ceramic), it maintains stable performance in a wide temperature range of -40°C to +85°C, meeting the demands of demanding outdoor and industrial environments.

Main Applications

Consumer Electronics: WiFi and Bluetooth signal reception for smartphones, tablets, smartwatches, and other devices.

In-Vehicle Communications: GPS/Beidou signal reception for in-vehicle navigation systems and vehicle-to-everything (V2X) communications.

Internet of Things (IoT): Data transmission for smart sensors and smart home devices.

Medical Devices: Wireless communication modules for portable medical monitoring devices.

Aerospace: Lightweight antenna solutions for drones and satellite communications equipment.
