25*25*5.3mm WPC.25B.35 2.4GHz Ceramic Patch Antenna with on-board MMCX(F)

WPC.25B.35 2.4GHz Ceramic Patch Antenna 

The WPC.25B.35 2.4 GHz Ceramic Patch Antenna is an excellent solution for Wi-Fi®, ZigBee®, Bluetooth® and ISM band at 2.4GHz. It has a PCB under the ceramic antenna with a MMCX female mounted connector mounted to the back-side, allowing for simple installation in tight device environments, and can be placed directly over metal ground-planes without compromising performance.

The antenna can be stuck to the inside of a plastic enclosure by adding adhesive tape or glue. Attaching a cable between the MMCX connector and device PCB completes the connection. Taoglas offers many types of suitable cable assemblies from MMCX(M) to U.FL, MMCX(M) to SMA, MMCX(M) to TNC, MMCX to FAKRA, etc.

This passive patch antenna has a typical gain response from 2.5 dBi. The radiation pattern is largely omnidirectional, with no distinct nulls, allowing for broad coverage area for wireless applications. Higher gain can be achieved, depending on the ground-plane, the space available, and clearance afforded. The antenna also delivers more than 70% efficiency across the band. The WPC.25B.35’s high gain performance and excellent efficiency make it a perfect solution for metering and remote monitoring applications. The ceramic used is robust and reliable, can be used in automotive environments.

Many module manufacturers specify peak gain limits for any antennas that are to be connected to that module. Those peak gain limits are based on free-space conditions. In practice, the peak gain of an antenna tested in free-space can degrade by at least 1 or 2dBi when put inside a device. So ideally you should go for a slightly higher peak gain antenna than mentioned on the module specification to compensate for this effect, giving you better performance.
