Taoglas WDP.2458.25.4.B.02 Embedded Ceramic Patch Antenna – LOT OF 45

The Taoglas WDP.2458.25.4.B.02 is a dual‑band (2.4 GHz / 5.8 GHz) ceramic patch antenna designed for embedded WiFi applications (IEEE 802.11). 
It measures 25 mm × 25 mm × 4 mm and is a pin‑type mount combined with double‑sided adhesive for mounting. 
It offers relatively high gain for this class of embedded antenna, making it a good choice when longer range or higher performance is required rather than a simple low‑cost omnidirectional chip antenna.

Key Specifications

• Frequency bands: 2 400 – 2 500 MHz and 5 150 – 5 850 MHz.

• Peak gain: Up to ~6 dBi in 2.4 GHz band; up to ~8 dBi in the 5‑6 GHz band.

• Impedance: 50 Ω nominal.

• Mounting: Pin plus double‑sided adhesive.

• Dimensions: 25 mm × 25 mm × 4 mm

• Operating temperature: Typically –40 °C to +85 °C.

• Designed for a ~70 mm × 70 mm ground plane.

• Efficiency: On average 60%+ across the bands (as claimed by manufacturer) which is high for such embedded antenna modules.

• Polarization: Dual linear polarizations (one for each band) to improve isolation between bands.

Typical Applications

This antenna is suited for professional/industrial‐grade WiFi dual band systems, including:

• Access Points, high‑throughput routers.

• Embedded WiFi modules in tablets, automotive infotainment, industrial in‑wall WiFi systems.

• Drones / UAVs, remote control systems that require dual‑band WiFi coverage with better gain.
