ZDTECH ZD0618 Planar Helical Antenna covers 6-18GHz wide frequency band, supports right-hand circular polarization, with VSWR ≤2.5. The gain is ≥-4.5dBi within ±45° in azimuth and elevation. It uses aluminum alloy cavity and 316L stainless steel SMA-K connector, with size ≤30mm×35mm, weight ≤45g, and adapts to -50℃ to +65℃ temperature range. With gray appearance, it’s suitable for high-frequency communication, testing and other scenarios.

Product Detail

The ZD0618 Planar Helical Antenna launched by ZDTECH is a high-performance communication component specially designed for high-frequency scenarios. It covers a wide frequency band of 6-18GHz and can stably meet the needs of various high-frequency signal transmission. Adopting right-hand circular polarization design, the antenna can effectively reduce signal interference and ensure transmission stability. Meanwhile, with a VSWR of ≤2.5, it can still maintain low signal reflection under high-frequency working conditions, improving signal utilization efficiency.

In terms of signal coverage performance, the antenna has a gain of ≥-4.5dBi within ±45° in both azimuth and elevation, which can achieve a wide signal coverage range and meet the needs of multi-directional signal reception and transmission. In structural design, the antenna uses an aluminum alloy cavity, which combines light weight and durability. With an overall size of ≤30mm×35mm (excluding the connector) and a weight of ≤45g, it can be easily adapted to installation scenarios with limited space; the connector is a 316L stainless steel SMA-K type, which has strong oxidation resistance and high connection stability.

In addition, the antenna has excellent environmental adaptability, with both operating and storage temperatures ranging from -50℃ to +65℃, allowing it to operate normally in harsh environments such as high and low temperatures. It has a gray appearance that fits various equipment appearance styles, and is widely used in high-frequency communication systems, electronic test instruments, radar signal processing and other fields.
