SPECIFICATION Part No. : WCM.01.0151 Product Name: : 2.4GHz Button Antenna Features : Tiny Size – 19.8mm*14.3mm*16.4mm 2400MHz to 2500MHz Antenna Wi-Fi / Bluetooth 60%+ Efficiency RP SMA(M) Connector IP67 Omnidirectional ROHS Compliant Photo: SPE-16-8-24/B/WY Page 1 of 30 1. Introduction The WCM.01 2.4GHz antenna is the smallest RP-SMA(M) external antenna in the market, fitting into spaces no other traditional monopole, dipole or rubber ducky antenna can go. A unique PIFA design ensures omnidirectional gain across 2.4GHz to 2.5GHz ensuring constant reception and transmission to make it a great Wi-Fi antenna for 2.4GHz Wi-Fi and Bluetooth applications. This antenna features greater than 60% efficiency when connected directly to the ground plane of the device. Typical Applications - Application Points - Routers - IoT M2M devices - Smart home applications This antenna comes with a RP SMA(M) to be compatible with most Wi-Fi applications and routers in the market. The WCM.01 antenna is also IP67 water resistant. The ideal position for the antenna to radiate is mounted clear of metal. Connector is customizable.
