Product Detail

The ZD6183624 planar helical antenna, manufactured by ZDTECH, is a high-performance device designed for high-frequency signal transmission. It covers a wide operating frequency range of 6-18GHz, meeting the needs of signal reception and transmission in various scenarios. Adopting right-hand circular polarization, the antenna has a VSWR ≤2.5, ensuring excellent signal transmission stability; its typical gain is ≥3dBi, and can even reach ≥6dBi at the 12GHz frequency band, guaranteeing signal transmission strength.

In terms of beam coverage, both the azimuth and elevation beamwidths are ≥90° (when absolute gain ≥-5dBi), and even when the absolute gain is ≥-1dBi at 12GHz and 18GHz, the beamwidth still remains ≥90°, providing a wide coverage range. The antenna features a compact size of ≤43mm×43mm×42mm (excluding the socket) and a light weight of only ≤0.07kg, facilitating easy installation and deployment. The cavity is made of aluminum alloy, matched with an SMA-50K stainless steel interface, ensuring a sturdy and durable structure. It also has excellent environmental adaptability, with an operating temperature range of -40℃ to +55℃ and a storage temperature range of -55℃ to +70℃. The military green appearance makes it more suitable for harsh application scenarios, and it is applicable to high-frequency fields such as communication and detection.
