Miniature antenna for small PCBs in 1559-1609 MHz GNSS devices

Antenova has unveiled Beltii, (P/N SR4G013), a new embedded antenna which measures only 15.6mm x 3.3mm x 4.4mm, and operates with all global public satellite constellations. The innovative antenna is designed to work over a very small ground plane on a small PCB, where it can be placed in a corner position, and does not need any ground clearance. Beltii works with all of the world’s public satellite constellations: GPS, GLONASS, BEIDOU and GALLILEO, and can add a positioning capability to any small, lightweight device. It is suitable for wearable electronics, trackers, drones, navigation devices, and sports applications, says the company. It is company's latest lamiiANT range antenna manufactured from FR4 materials and uses the latest in dielectric constant laminate substrates to construct smaller, more efficient antennas. Commenting, Antenova’s CEO, Colin Newman, said: “Beltii is a brand new design using new materials. It beats the typical larger, ceramic patch antennas on all counts: it is smaller, more efficient, and performs better. It is a great addition to our range of positioning antennas.” As the performance of a wireless device depends upon the performance of its antenna, and the performance of the antenna depends upon how it is integrated into the PCB, Antenova’s antenna designers give the integration requirement top priority and design each antenna so that it can be integrated easily, and to perform well in situ within the device. Antenova calls this concept DFI, or Design For Integration. Evaluation boards (P/N SR4G013-U1) are also available, says the company.
