Antenova Ltd., manufacturer of antennas and RF antenna modules for machine-to-machine (M2M) and the Internet of Things, is adding two new positioning antennas to its range of flexible FPC antennas. Bentoni is a positioning antenna for all of the global public satellite constellations: GPS, GLONASS, BeiDou and Galileo. It is designed to be used in trackers, portable devices, network components, drones and wearable electronics. Asper is a dual antenna with two separate antenna systems in a single form factor. It combines a 1559–1609 MHz antenna with a 2.4–2.5 GHz antenna in the same part for positioning applications with wireless connectivity as well. This antenna is suitable for sports cameras, trackers, dash cams, portable devices, network devices and wearable electronics. Both antennas offer high performance and maintain good isolation in situ within a device. Bentoni and Asper are the latest flexible FPC antennas in Antenova’s flexiiANT product range. They are supplied with an I-PEX MHF connector and a 1.13 mm RF cable in a choice of three lengths. They can be folded to save space in operation within a device. Antenova’s antenna design team aims to create antennas that a product designer can integrate with the other circuits in a design in a convenient way, rather than designing a product to fit around the antenna. The aim of these antenna designs is plug and play simplicity — they are self-adhesive mounted so that they can easily be fixed inside an electronic device. Bentoni antenna and Asper antennas are available to order now.
