wideband 2GHz~18GHz plane spiral antenna
ZD20180D32-AP is a 2GHz~18GHz broadband plane spiral antenna array launched by ZDTECH, adopting a right-handed circular polarization design with a typical axial ratio ≤3dB and a typical VSWR ≤2.5. Within the spatial coverage of ±45° azimuth and ±45° elevation, its gain increases in stages with the frequency band: the gain is ≥-14dBi at 2~2.5GHz, ≥-8dBi at 2.5~3GHz, and ≥-5dBi at 3~18GHz. The proximal paravalve is ≥10dB within the range of ±90° azimuth and pitch, and the beam width is adapted to the application requirements of the full frequency band. The product is equipped with a stainless steel SMA-50K connector, and the antenna cavity is made of alufer.
The overall size is ≤32.5mm32.5mm33.8mm (excluding connectors) and the weight is ≤60g, featuring compact and light design for easy integration. With an impedance of 50Ω and a continuous wave power handling capacity of 5W, it has excellent vibration resistance: it can withstand 14.8g vibration in the X axis and 12.7g vibration in the Y/Z axis with a single-axis test duration of no less than 4 hours. Its operating temperature ranges from -50℃ to +70℃ and storage temperature from -55℃ to +60℃, which can adapt to harsh high and low temperature and vibration environments, and is suitable for various scenarios such as radio frequency communication and electromagnetic testing.
