HELICAL 3.0-3.5 GHz Antenna — Overview

HELICAL 3.0-3.5 GHz 12 dBi RHCP, 12-turn, Open-Type SMA Antenna from SkyReach is a high-performance radio communication component designed for stable operation in the 3.0 - 3.5 GHz range. This circular (helical) antenna provides a directional signal with high gain and stable right-hand circular polarization (RHCP), making it an ideal choice for applications where reliability and minimization of signal loss are critical.

Description and Purpose

The antenna is designed for use in communication systems requiring focused coverage and high sensitivity. Its open design and SMA connector allow for quick integration into various solutions: unmanned platforms, telecommunication lines, access points, and specialized radio systems. The right-hand circular polarization (RHCP) ensures better resistance to multipath interference and losses from multipath signal propagation.

Key Features

• Frequency Range: 3.0 - 3.5 GHz
• VSWR (Voltage Standing Wave Ratio): Less than 1.5
• Antenna Conductor: 1 mm enameled copper wire
• Coverage Angle: 39°
• Gain: 12 dBi
• Number of Turns: 12
• Polarization: RHCP (Right-Hand Circular Polarization)
• Type: Open-type
• Connector: SMA

A VSWR value of less than 1.5 indicates good impedance matching between the antenna and the feeder line, as well as minimal reflected waves, which helps reduce energy loss. The 1 mm enameled copper conductor ensures the strength and durability of the radio frequency element. A 39° coverage angle forms a compact beam pattern, and 12 dBi gain provides communication range and quality in the selected frequency band.
