Product Detail

Developed by ZDTECH, the ZD10180 planar spiral antenna array is a high-performance antenna covering an ultra-wide frequency range of 1GHz~18GHz, suitable for multiple fields such as communications, electronic testing, and RF signal transmission. In terms of core performance, the antenna adopts a right-handed circular polarization design to ensure the stability of signal transmission; the gain is dynamically optimized with frequency bands: -20dBi~-6dBi in the 1GHz~2GHz range, increased to -6dBi~2dBi in the 2GHz~6GHz range, and further reaching 2dBi~7dBi in the 6GHz~18GHz range. Meanwhile, the standing wave ratio is ≤2.5 (typical value), effectively reducing signal loss.

It is equipped with an SMA-50K interface, which has wide device compatibility and can be quickly connected to various RF modules and testing instruments. In terms of structural design, the antenna cavity is made of aluminum alloy, balancing durability and lightweight requirements. The overall dimensions are ≤100mm×80mm×35mm and the weight is ≤180g, making it easy to install and carry; the appearance is matte black, which not only enhances the visual texture but also reduces the impact of ambient light reflection on use.

In terms of environmental adaptability, the antenna has an operating temperature range of -20℃~+55℃ and a storage temperature range of -20℃~+70℃, which can operate stably in environments with high and low temperature fluctuations. There is no need to worry about the impact of extreme climates on performance, providing a guarantee for long-term reliable use.
