All-band GNSS Embedded Quad Helix Antenna

Overview

All-band GNSS Embedded Quad Helix Antenna

The EAHP.125 is an embedded all-band GNSS Quadrifilar Helix antenna. It covers the full GNSS L1/L2/L5/L6 spectrum while also covering the L-Band for correction services deployed by U-Blox and other providers. The EAHP.125 has right hand circular polarization which improves sensitivity, rejecting left hand circular polarized reflections commonly experienced in urban environments.

The EAHP.125 is a dual stage active GNSS antenna, thus saving time for the customer as they don’t need to create a complicated active circuit to be used in conjunction with their GNSS receiver/module, for multiband GNSS this can be a difficult process so it will save design time for users.

The EAHP.125 is extremely compact at just 31.5mm in height and 60mm in diameter. It is also very lightweight due to its lightweight construction. The height and weight constraints of many devices often don’t allow for a large ceramic antenna. For example, UAVs and other robotic applications often will have weight restrictions to maximize battery life and, so the optimum solution is the EAHP.125.

Typical Applications include:
– UAVs and Drones
– Robotics and Autonomous
– Transportation
– Aerospace
– Surveying

The EAHP.125 installation method is detailed in section 7 of this datasheet and requires an adhesive pad (supplied with the antenna) to ensure the antenna is secured in place when it is installed in a device. Any movement of the antenna within the device may cause damage to the antenna which will affect performance. Contact Taoglas if you are unsure of any installation requirements or require more details.

The cable and connector are fully customizable, for further information please contact your Regional Taoglas Customer support team.
