Product overview
The GEPRC SOMA 3.3G Directional Patch Antenna provides directional signal reception through a dual-layer PCB RF design. It operates at a center frequency of 3.3GHz with a bandwidth of 3.0GHz~3.5GHz and RHCP polarization. Gain is 17dBi, radiation efficiency is 86%, and SWR is ≤1.47. The antenna also has an axial ratio of ≤3 and cross polarization suppression of -25dB. Its SMA connector uses an external thread and internal hole.
The smooth, ultra-thin flat-panel construction combines an ABS enclosure with an integrated injection-molded casing and a 1/4 aluminum alloy base. The base accommodates various brackets, providing mounting flexibility. Overall dimensions are 203.5mm x 203.5mm x 20mm, and antenna weight is 293g. The dual-layer RF assembly sits within this slim enclosure, bringing the directional antenna into a single panel format. The package includes one SOMA 3.3G Directional Patch Antenna.
