6-18GHz Wide Beamwidth Circularly Polarized Planar Spiral Antenna

The ZD60180-25 planar spiral antenna is a high-performance product designed for wideband communication scenarios, covering the 6GHz~18GHz frequency range to meet multi-band signal transmission needs. Adopting circular polarization technology, the antenna has a 5dB absolute gain beamwidth of ≥90° in both the azimuth plane and pitch plane, with a gain of ≥-5dB at ±45°, ensuring wide signal coverage and strong transmission stability; the VSWR is ≤3.0, which effectively reduces signal reflection loss and guarantees signal transmission efficiency.

In terms of structure and material, the antenna uses Alufer cavity material, which combines light weight and durability. Its overall size is 25mm×25mm×30mm (without connectors, tolerance ±2mm) and weighs ≤30g, making it suitable for installation scenarios with limited space; the connector adopts the SMA-50K stainless steel type, ensuring firm connection and corrosion resistance. In addition, the antenna supports an operating temperature of -40℃~+55℃ and a storage temperature of -55℃~+70℃, capable of coping with complex temperature environments. It is available in two appearance options: military green and gray, adapting to different application needs, and is widely used in communication equipment, testing instruments and other fields that require high antenna performance and stability.
