Echo 445G C-Band and Wi-Fi 7 Flexible Printed Circuit Antenna

The Echo 44 is a flexible printed circuit antenna designed for Wi-Fi 6E and Wi-Fi 7 technologies, operating efficiently across the 2.4 GHz, 5 GHz, and 6 GHz Wi-Fi bands. With an exceptional radiation efficiency of up to 90%, a low VSWR, and a gain of 3-5 dBi, this omnidirectional antenna ensures robust coverage across the Wi-Fi spectrum.

Additionally, this antenna supports the 5G C-bands n48, n77, and n78, enhancing its versatility in modern communication applications.Constructed with a flexible polyimide (PI) substrate, etched with precision copper tracks for radiating elements, and backed with an adhesive layer for easy mounting, this ground plane independent antenna can be positioned on both flat and curved surfaces without compromising RF performance.

This capability allows for versatile placements in applications where mounting flexibility and space optimisation are paramount. Terminated with 100 mm of 1.13 mm coaxial cable, with I-PEX MHF1 (uFL), I-PEX MHF4 or SMA male connectors as standard, the Echo 44 can be customised with other cable lengths and connector types for high volume projects.
