Why use a GNSS helix antenna for UAVs and drones?

As the use of UAVs and drones proliferate across military and industrial applications, a key component in their design is the use of GNSS antennas. The obvious choice is between a GNSS patch style antenna and a GNSS helix antenna. Here are some of the main reasons for choosing a GNSS helix antenna for UAVs and drones.

Compact and Lightweight

Given the environment, the more compact and lightweight the GNSS antenna is the better. Typically, GNSS helix antennas can weigh in the region of 30g to 40g which is ideal for weight critical applications. For example, the ELX1512 antenna weighs 37g including its integral SMA-Male connector. The embedded version weighs just 31g.

Small Footprint

UAV and done designs do not need a square GNSS patch antenna taking up a lot of “real estate” on their platform. By definition, patch antennas are flat and square which is often impractical. GNSS helix antennas in contrast have a small footprint, often based on a SMA connector which can be augmented by further mounting holes on some models. This small footprint makes installation on UAVs and drones a lot more attractive.

Support for multi-constellations

GNSS Helix antennas are very suitable for wideband operation without compromised their compact form factor. GPS L1/L2 or L1/L5 bands are easily covered with excellent RF performance.

Highly accurate

Higher quality GNSS helix antennas have highly focused and consistent phased centres meaning that their inherent stability allows for incredibly precise positioning across multiple frequency bands.

Groundplane independent

As GNSS Helix antennas are often groundplane independent, they work well on non-metal surfaces such as the typically composite structure of a drone or UAV. This characteristic is also beneficial for portable and mobile devices where the enclosure may be polycarbonate or similar and no groundplane is available.

High Gain

GNSS helix antennas can offer high gain across the multi-constellation bands. Incorporating effective and efficient Low Noise Amplifiers (LNAs), GNSS helix antennas can offer predictable and consistent performance.

Active GPS Stub Antenna

Active GPS Stub Antenna with Right Angle SMA

The unique GPS-Stubby from EAD is the only active GPS stub antenna with either SMA-Male straight or SMA-Male right angle.

Some GPS-based terminal and devices are not suitable for straight GPS stub antennas. Our GPS-Stubby right angle version solves this problem.

The GPS-Stubby is an active antenna with an integrated LNA (low noise amplifier) to enhance signal reception. Housed in a robust, aesthetically attractive sheath, the antenna is ideal for systems where an embedded internal antenna or a magnetic mount antenna cannot be used.

For customers in Europe, you can purchase small quantities of the GPS-Stubby antenna via the Connex Webshop. For all other requests, please contact your local EAD distributor.
