Specification Part No. : WCM.01.0111 Product Name: : 2.4GHz Button Antenna Features : Tiny Size 19.8mm*14.3mm*16.4mm 2400MHz to 2500MHz Antenna Wi-Fi / Bluetooth >60% Efficiency Connector: SMA(M) IP67 Waterproof Housing Omni directional ROHS Compliant SPE-17-8-090/A/IC Page 1 of 31 1. Introduction The WCM.01 2.4GHz antenna is the smallest SMA(M) connector mount external antenna in the market, fitting into spaces no other traditional monopole, dipole or rubber ducky antenna can go. Its unique PIFA design provides omni-directional gain across the 2.4GHz to 2.5GHz range, ensuring constant reception and transmission 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 Include: - Application Points - Routers - IoT M2M Devices - Smart Home Applications The WCM.01 antenna has an IP67 water proof enclosure and comes with an SMA(M) connector, making it compatible with most Wi-Fi applications and routers on the market. An RP-SMA(M) version is also available, WCM.01.0151. For ideal radiation, mount the WCM.01 clear of metal. Many module manufacturers specify peak gain limits for any antennas that are to be connected to that module. Those peak gain limits are based on freespace conditions. In practice, the peak gain of an antenna tested in freespace can degrade by at least 1 or 2 dBi when put inside a device. So ideally you should go for a slightly higher peak gain antenna than mentioned on the module specification to compensate for this effect, giving you better performance. SPE-17-8-090/A/IC Page 2 of 31
