SPECIFICATION Part No. : WCM.01.0151W Product Name: : 2.4GHz Button Antenna Features : Smallest External Wi-Fi/Bluetooth Antenna 2dBi˜5dBi Peak Gain Dims: 19.8*14.3*16.4mm 2400MHz to 2500MHz Antenna Wi-Fi/Bluetooth 60%+ Efficiency RP SMA(M) Connector IP67 Housing Omnidirectional ROHS Compliant *Gain varies depending on ground-plane size SPE-16-8-079/A/WY Page 1 of 30 1. Introduction The WCM.01w 2.4GHz antenna is the smallest RP-SMA(M) external antenna in the market, fitting into spaces other traditional monopole, dipole or rubber ducky antenna cannot go. A unique PIFA design ensures omnidirectional gain across 2.4GHz to 2.5GHz ensuring constant reception and transmission to make it a great 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 an RP SMA(M) to be compatible with most Wi-Fi applications and routers in the market. The WCM.01 antenna housing is also IP67 water resistant. The antenna should be mounted on the edge of the main PCB ground-plane of the device. Due to its monopole design, relatively larger ground-planes will increase the efficiency and peak gain of the antenna. The ideal position for the antenna to radiate is mounted clear of metal housings. Connector is customizable subject to minimum order quantities and possible NRE.
