A new antenna, the Agosti, part number SR4G080, measures 9.0 x 5.8 x 1.7 mm and operates with exceptional efficiency in a reduced space on a corner of a PCB.
A key advantage is its small ground plane requirement. Most SMD antennas use the surface of the PCB around the antenna as a ground plane to radiate signal from, so it is the ground plane requirement not the physical dimensions of the antenna that defines the space it needs.
Antenova’s radiated measurement results show Agosti operating well on small ground planes of 40 x 20 mm, 70 x 25 mm and 80 x 30 mm, making it a suitable choice for small form factor designs.
Agosti also offers designers some additional layout options, as it is designed to be placed on a corner of their PCB.
The antenna is designed to integrate and co-exist with other antennas within the same device. On Board Diagnostics (OBDs) and trackers often use 4G/LTE with A-GPS for fall-back and the Agosti antenna has been tested with Antenova’s Pharoah antenna, part number SR4L073, which also has a very small ground plane requirement. The two antennas have excellent isolation and can operate in close proximity to each other in a very small device without the 4G signal interfering with sensitive GNSS signals.
