The ZD269058 planar helical antenna is a high-performance wideband antenna launched by ZDTECH, covering a core operating frequency band of 2-6GHz, which can meet the signal transmission needs of various wideband communication scenarios. Adopting a right-hand circular polarization design, this antenna can effectively reduce polarization loss during signal transmission and ensure communication stability; with a standing wave ratio ≤2.5, it has excellent signal matching performance, which can reduce signal reflection loss and improve energy utilization efficiency.
In terms of signal coverage and gain, both the azimuth and elevation beamwidth of the antenna are ≥90° (absolute gain ≥-4dBi), and the beamwidth (absolute gain ≥-2dBi) remains ≥90° in the 4GHz frequency band, providing a wide coverage range; the normal gain is ≥3dBi, and the gain can be increased to ≥6dBi in the 4GHz frequency band, featuring outstanding signal transmission strength and long-distance communication capability.
In terms of structure and environmental adaptability, the antenna has a reference dimension of ≤90mm×90mm×45mm (excluding the socket) and a weight of ≤0.17kg, which is compact and lightweight, facilitating installation and deployment; the cavity is made of aluminum alloy, which combines structural strength and heat dissipation performance, and is equipped with an SMA-50K stainless steel interface for stable connection and corrosion resistance; it has a military green appearance and excellent temperature range adaptability, with an operating temperature range of -40℃~+55℃ and a storage temperature range of -55℃~+70℃, enabling stable operation in complex high and low temperature environments.
