WDP.2458.25.4.B.02 Specification **Part No. WDP.2458.25.4.B.02 Product Name** Wi-Fi Dual-band 2.4/5 GHz Embedded Ceramic Patch Antenna 6dBi+ at 2.4GHz 6dBi+ on 5 to 6 GHz **Feature** 25mm*25mm*4mm 2400MHz to 2500MHz/5150MHz to 5850Mhz Pin Type Supports IEEE 802.11 Dual-band Wi-Fi systems Dual linear polarization Tuned for 70x70mm ground plane RoHS Compliant SPE-14-8-039/A/WY | page 1 of 12 **==> picture [131 x 40] intentionally omitted <==** ## **1. Introduction** This unique patent pending high gain, high efficiency embedded ceramic patch antenna is designed for professional Wi-Fi dual-band IEEE 802.11 applications. It is mounted via pin and double-sided adhesive. The passive patch offers stable high gain response from 4 dBi to 6dBi on the 2.4GHz band and from 5dBi to 8dBi on the 5 ~6 GHz band. Efficiency values are impressive also across the bands with on average 60%+. The WDP.25’s high gain, high efficiency performance is the perfect solution for directional dual-band WiFi application which need long range but which want to use small compact embedded antennas. The much higher gain and efficiency of the WDP.25 over smaller less efficient more omni-directional chip antennas (these typically have no more than 2dBi gain, 30% efficiencies) means it can deliver much longer range over a wide sector. Typical applications are: - Access Points - Tablets - High definition high throughput video streaming routers - High data MIMO bandwidth routers - Automotive - Home and industrial in-wall WiFi automation - Drones/Quad-copters - UAV - Long range WiFi remote control applications The WDP patch antenna has two distinct linear polarizations, on the 2.4 and 5GHz bands, increasing isolation between bands. Custom tuned versions for different ground-planes and housing environments can be made subject to a minimum order quantity.
