Product details

Internal PCB Antenna Wi-Fi 2.4G Embedded Antenna

This is a PCB antenna assembly is designed to cover the WLAN frequency bands of 2.4 to 2.5 GHz.


These are also PCB antenna assemblies, with 65-mm cables and standard IPEX connector for ease of connection to an application. The antenna assemblies, which offer high efficiency of better than 50%, are designed for internal mounting in Wi-Fi products. The 2.4-2.5Ghz band coverage represents a practical antenna solution for industrial applications and IoT devices as well as applications in Public Safety devices.


The ease of mounting such PCB antennas using adhesives may at times result in the absence of a ground plane of any kind, which reduces efficiency. While the underside of an PCB antenna laminate is typically a ground plane, the larger ground planes required for higher efficiency can add to the physical size of an PCB antenna and must be considered when mounting the antenna in an application.
