Johanson Technology, Inc. Single Band Chip Antenna, 2.4Ghz, 50 Ohm; Centre Frequency Johanson Technology 2450AT42E010BE

The Single Band Chip Antenna, part number 2450AT42E010B, operates at a center frequency of 2.4 GHz with a 50 Ohm impedance. It is designed for surface mount applications and can be placed directly above or below a metal layer on a PCB, eliminating the need for antenna clearance. The antenna has a typical gain of -2.0 dBi and a maximum power capacity of 2W. It is suitable for use in small, close-range networks, including IoT, BLE, and Zigbee applications, particularly in devices with limited space such as wearables and coin cell powered devices. The operating temperature range is from -40¬8C to +85¬8C, and it is RoHS compliant. The antenna's performance is influenced by the substrate thickness, with optimal efficiency achieved on PCBs with a thickness of 1-2 mm.
