Multiband IoT Antenna

Multiple frequency, protocol, and functionality solutions for IoT connectivity continue to push size and performance limits. To address this, Johanson Technology developed a multiband flexible solution using one antenna. This solution covers cellular (LTE), sub-GHz (868/915 MHz), GPS and/or GNSS (GLONASS), 2.4 GHz (Bluetooth® and/or Wi-Fi®) using one SMT chip antenna and two 6-channel RF switches. The entire solution requires a PCB area of about 360 mm, making it very compact with industry-accepted radiated gain and efficiency in a 51 mm x 51 mm board..

Features

• Single antenna matching solution to cover all relative frequency bands
• Can resonate at multiple frequencies
• Requires antenna matching networks to cover cellular/sub-GHz/GPS-GNSS/2.4 GHz bands to achieve high efficiency and bandwidth
• Entire solution requires a PCB area of about 360 mm, making it very compact with industry-accepted radiated gain and efficiency in 51 mm x 51 mm board
