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.
