Flexible PCB Antenna for future-proof device design for 5G and 4G globally

The patent-pending Maximus FXUB66 flexible wideband antenna is an IoT antenna with 70-80% 5G/4G Efficiency.  It has been designed to cover all working frequencies in the 650-6000 MHz spectrum, including all Cellular, Wi-Fi, ISM and GNSS bands. Its use in a device improves substantially the radiated power and sensitivity and enables the highest throughput rates of today’s broadband devices.

The antenna is delivered with a flexible body with groundbreaking high efficiencies on all bands, ground-plane independent, with a cable and connector for easy installation. It is made of durable flexible polymer, with a peak gain of 5dBi, an efficiency of more than 60% across all cellular bands and is designed to be mounted directly onto a plastic or glass enclosure/cover.

At 120.4×50.4x.2mm, the antenna is ultra thin. It is assembled by a simple “peel and stick” process, attaching securely to non-metal surfaces via 3M adhesive. It enables designers to use only one antenna that covers all frequencies and has future-proofed device design for 5G and 4G globally with 5G/4G frequencies becoming the norm to be used industry-wide. It is also the ideal antenna to fit in devices that are being retrofitted with wireless functionality, as it will cover non-cellular applications such as 868, 915MHz or Zigbee applications. It’s inherently wide bandwidth is more resistant to detuning than traditional small but narrow-band legacy antennas.

Cables and connectors are customizable. Contact our customer services team for more information on customization and testing the antenna in your product. A variation of the FXUB66 is fitted with a regular SMA connector.


The Maximus antenna has a unique hybrid design. Within one antenna structure the electromagnetic waves travel in two predominant propagation modes – one for lower frequencies, (e.g. 5G at 650 MHz) and the other for higher 5G/4G and Wi-Fi frequencies up to 6GHz. It is an ideal choice for any device maker that needs to keep manufacturing costs down over the lifetime of a product, as the same antenna can be used if the radio module is upgraded to work on a different frequency band.
