SPECIFICATION Part No. : WLP.2450.25.4.A.02 Specification No : DA2450C Product Name : 2450MHz Patch Antenna Features : 25mm*25mm*4.5mm ROHS Compliant : SPE-11-8-033/B 11 July-11 Page 1 of 11

1.0 Introduction This WLP.25 patch antenna for ISM, Wi-Fi, Bluetooth and Zigbee is based on smart XtremeGain™ technology. It is mounted via pin and double-sided adhesive and has been selected as optimal solution for the 50*50mm ground plane. This passive patch offers typical gain response from 2.5 dBi and a higher gain can be achieved, depending on the Ground Plane, the space available and clearance afforded. The WLP.25’s high gain performance is a perfect solution for metering and remote monitoring applications; it can deliver longer range than smaller chip antennas. 2.0 Key Antenna Performance Indicators Original Patch Specification tested on 50*50mm ground plane No Parameter Specification Notes 1 Range of Receiving Frequency 2450±50Mhz with 50*50mm GND 2 Center Frequency 2482MHz Plane 3 Bandwidth 85 MHz min Return Loss £-10dB 4 VSWR 1.5 max Center Frequency 5 Gain at Zenith +5.0dBi typ.
