Key Features and Performance of the 380-2000MHz Planar Helical Antenna
n
Wideband Operation and Circular Polarization Advantages
n
Operating across a broad frequency spectrum of 380MHz to 2000MHz, the 380-2000MHz Planar Helical Antenna provides excellent signal propagation characteristics. Its right-handed circular polarization minimizes signal degradation from reflections and multipath interference, ensuring cleaner and more reliable transmission. This makes it particularly suitable for IoT device networking in commercial buildings and outdoor signal coverage for remote equipment monitoring in industrial yards.
n
Gain and Beam Width Specifications
n
The antenna delivers a gain of ≥-0.5dB, with a beam width of ≥90° across the full operating range. For critical low-frequency segments, the absolute gain remains better than -4dB for 380 to 500MHz, while mid-to-high frequencies from 500 to 2000MHz achieve an absolute gain better than -2dB. This performance ensures effective signal coverage and transmission stability, even in challenging environments.
n
Additional performance metrics further validate its reliability: a standing wave ratio (VSWR) of ≤2.5 minimizes signal reflection, and a back lobe specification of ≤-12dB reduces interference from unwanted directions. The SMA-K type stainless steel connector ensures secure, low-loss signal connectivity, which is vital for maintaining system integrity.
