RangeAnt, specialists in broadband antennas for in-vehicle applications, announces the MAX family of compact antennas from 700 MHz to 3000 MHz. MAX antennas are designed primarily for cellular, IoT and GNSS applications. They feature 80-90% free space efficiency and less than 2:1 VSWR across all bands of operation.
The efficiency of the antennas provides greater range for the available transmit power and improved receive performance. Alternatively, when reducing power consumption is a priority, such as in IoT applications, lower transmit power can be used for a given link range. MAX antennas are suitable for use with Bluetooth, Zigbee, Sub-GHz, LPWAN (LoRa, Sigfox, Weightless), Wi-Fi and Cellular (2G, 3G, 4G/LTE and NB-IoT) and GPS/ GNSS HOME. They allow wireless module manufacturers and OEMs to create products for global markets while minimizing design effort and inventory by using only one type of antenna. Optimum performance is achieved without the use of a separate ground plane, allowing design freedom for mechanical and electrical engineers. The antenna can be integrated into a product regardless of a ground plane and without compromising wireless reliability or signal quality. RangeAnt MAX antennas feature a patent pending double sided board design where the conductor patterns are different on each side of the board. Omnidirectional antennas operate as a monopole up to 1600 MHz and a dipole above that frequency. They are designed for a 50 ohm match in free space, but when integrated into a wireless module or system, maintaining optimum efficiency can sometimes require additional matching components. The antenna board includes pads for installation of corresponding surface mount components, if required. RangeAnt offers advice on suitable matching networks and matching services for specific applications. Hans-Erik Backram, CEO of RangeAnt, said, “Our research indicates that MAX antennas provide 20% better performance than the closest wideband antenna alternatives. This gives system designers greater flexibility to optimize the trade-off between operating range, data rates, and power consumption for their wireless links. For the first time, they can optimize their designs while working with a single antenna, regardless of the desired frequency band or wireless protocol. RangeAnt MAX antennas are now available in stock from Digi-Key Electronics.
