Antenova Ltd has added new products to its range of miniature patch antennas and modules created for GNSS applications. The new antenna Agosti, part number SR4G080, measures 9mm x 5.8mm x 1.7mm and offers excellent efficiency in the smaller space in the corners of the PCB. And it also provides designers with additional layout options as it is placed in a corner of the PCB.
The company's radiation measurements show that the antenna works well on small grounds of 40mm x 20mm, 70mm x 25mm and 80mm x 30mm, making it a suitable choice for small form factor designs. The main advantage of the antenna is the small ground plane. Most SMD antennas utilize the PCB surface around the antenna as a ground plane to radiate the signal, so the ground plane does not need the physical size of the antenna to determine the space it needs.
Michael Castle, Product Marketing Manager at Antenova, said: "Agosti's small ground plane and good isolation make it ideal for small wearables, trackers and freely moving obds. It offers both omnidirectional and small key advantage.”
"Small patch antennas like Agosti are an exciting alternative to the delicate ceramic patch antennas commonly found in GNSS designs. Not only because patch antennas are significantly smaller, but also because they offer a full range of performance. Chip antennas are typically 12mm or 14mm square, are heavier than patch antennas and require a larger ground plane and isolation area. They must also be placed in the center of the board and only work properly when they are pointed towards the sky. The new generation of Antenova Patch antennas overcome all these limitations and perform well regardless of the device's location and orientation."
