The patented Maximus FXUB66 flexible wideband antenna has been designed to cover all working frequencies in the 600-6000 MHz spectrum, including all Cellular (5G/4G/3G/2G), NB-IoT, Cat-M, 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 a 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 120.4×50.4×0.2mm, 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 future-proof device design for 5G and 4G globally. 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. Its inherently wide bandwidth is more resistant to detuning than traditional small but narrow-band legacy antennas.

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/4G at 600 MHz) and the other for higher 5G/4G and Wi-Fi frequencies up to 6GHz.
