A fundamental aspect of this antenna’s design is its single conductor configuration, a feature that contributes to its compactness and efficiency. Unlike multi-conductor cables, which are bulkier and more complex, a single conductor simplifies the antenna’s structure, reducing its overall size and weight. This design is particularly well-suited for GNSS applications, where the primary function is to transmit and receive high-frequency signals—tasks that can be efficiently handled by a single conductor. The simplicity of a single conductor also minimizes signal loss and interference, as there are fewer pathways for noise to enter the system. For compact devices where space is at a premium, this streamlined design ensures that the antenna can be integrated without compromising the device’s form factor or performance.

The conductor material is tinned copper, a choice that balances conductivity, durability, and cost-effectiveness. Copper is an excellent conductor of electricity, ensuring that GNSS signals are transmitted with minimal loss—a critical factor for weak satellite signals that require precise handling. The tin plating adds a protective layer, preventing corrosion and oxidation that could degrade conductivity over time. This is particularly important for antennas used in humid or harsh environments, where exposure to moisture or chemicals could otherwise damage the copper conductor. Tinned copper also enhances solderability, making it easier to attach the conductor to connectors or PCBs during manufacturing. For compact antennas, where every component must perform reliably in a small space, the combination of copper’s conductivity and tin’s protection ensures long-term performance and consistency.

Notably, the antenna specifies no fiber type, confirming that it relies solely on metallic conductors for signal transmission. This is consistent with GNSS technology, which uses radio frequency (RF) signals that do not require optical fibers. The absence of fiber simplifies the antenna’s design, reducing its complexity and cost while ensuring compatibility with standard RF receivers and modules. This makes the antenna a versatile choice for OEMs and developers working with traditional GNSS hardware, as it can be easily integrated into existing systems without the need for specialized fiber optic components.

The cable length of 320 mm is carefully chosen to balance flexibility and signal integrity. A longer cable would introduce excessive signal loss (attenuation) at GNSS frequencies, while a shorter cable would limit the antenna’s placement options within a device. The 320 mm length provides enough flexibility to route the antenna from its mounting position to the GNSS receiver, which may be located in a different part of the device, without significant signal degradation. This length is particularly useful for compact devices where internal components are densely packed, requiring careful cable routing to avoid interference with other electronics. For example, in a smartwatch, the antenna might be mounted near the watch face, while the receiver is located in the wristband— the 320 mm cable allows for this separation without compromising signal quality.

The cable diameter is specified as 1.37 mm outer diameter (OD), a small size that further contributes to the antenna’s compactness. This thin cable can be easily routed through tight spaces, such as the gaps between circuit boards or the seams of a wearable device, without adding bulk. The small diameter also reduces wind resistance and noise, making the antenna suitable for applications like drones or portable navigation devices where aerodynamics or user comfort are important. Despite its thin profile, the cable is designed to be robust enough to withstand bending and flexing during normal use, ensuring that it does not break or degrade with repeated movement.

With an impedance of 50 Ω, the antenna adheres to the industry standard for RF systems, ensuring compatibility with virtually all GNSS receivers, modules, and other RF components. Impedance matching is critical for maximizing power transfer and minimizing signal reflection, which can cause standing waves and reduce signal strength. A 50 Ω impedance is universally accepted in RF design, making this antenna compatible with off-the-shelf hardware from various manufacturers. This compatibility simplifies integration for OEMs, as they can pair the antenna with their preferred receivers or modules without the need for additional matching networks or adapters. For compact devices, where space and cost are key considerations, this plug-and-play compatibility is a significant advantage.
