2GHz~18GHz Plane Spiral Antenna

ZDTECH ZD201804 Plane Spiral Antenna Array is a high-performance RF device with a wide frequency band, covering an operating frequency range of 2GHz~18GHz and adopting the right-handed circular polarization mode. It features a typical standing wave ratio ≤2.5 and a back lobe ≤10dB, ensuring excellent signal transmission stability. The gain at the antenna beam center increases gradually with the frequency band, being ≥-7dBi at 2GHz and above and reaching ≥4.5dBi at 9/10GHz. The antenna has a highly adaptable beam width across different frequency bands, with an absolute gain ≥-5dBi within the 90° beam width at 3GHz and above.

The product's cavity is made of Alufer material and equipped with a stainless steel SMA-50K connector, boasting a robust structure. With a compact size of ≤55mm×55mm×40mm (excluding connectors) and a weight of ≤50g, it is small, light and easy to integrate. It has a wide temperature range with an operating temperature of -50℃~+70℃ and a storage temperature of -50℃~+65℃, adapting to various complex working environments such as outdoor and industrial scenarios, and is a cost-effective choice in the field of RF communication.
