2-18GHz Right-Handed Circular Polarization Plane Spiral Antenna

The ZD20180D32-AP2-18GHz Plane Spiral Antennaarray is a high-performance RF antenna with ultra-wide frequency band, whose core is designed as a2-18GHz Plane Spiral Antenna, covering the full frequency range from 2GHz to 18GHz. The gain in the coverage area is increased in stages, reaching ≥-14dBi at 2-2.5GHz, ≥-8dBi at 2.5-3GHz and ≥-5dBi at 3-18GHz. Combined with the space coverage of ±45° in azimuth and ±45° in elevation, it has excellent beam coverage capability. As a professionalRight-handed Circular Polarization Antenna, it adopts right-handed circular polarization with stable polarization characteristics, the typical axial ratio is ≤3dB, and the proximal isolation within ±90° azimuth and pitch is ≥10dB, bringing outstanding signal anti-interference performance. It also has the advantage ofLow Standing Wavewith a typical value of ≤3dB, realizing low transmission loss, equipped with 50Ω standard impedance and stainless steel SMA-50K connector, compatible with mainstream RF equipment, with 5W continuous wave power handling capacity, ensuring efficient and stable signal transmission.

This2-18GHz Plane Spiral Antennauses Alufer material for the antenna cavity, featuring a miniaturized design with size ≤32.5×32.5×33.8mm (excluding connectors) and weight ≤60g, easy for integration and installation. It has strong environmental adaptability, working at -50℃~+70℃ and storing at -55℃~+60℃, able to withstand complex high and low temperature working conditions; it also has excellent vibration resistance, with 14.8g vibration resistance in X direction (antenna normal) and 12.7g in Y/Z direction, and the vibration test of each axis is no less than 4 hours. The 3dB beam width is dynamically adapted to the frequency band with good pattern characteristics. Relying on the characteristics ofLow Standing Wave, wide frequency coverage and high isolation, thisRight-handed Circular Polarization Antennais suitable for harsh application scenarios in various fields such as industrial RF, microwave communication and wireless detection.
