TOXU BDS /L-BAND/(SDARS) Patch Antenna

RT4009 KC.GA.00083 Beidou Short Message Antenna

The KC.GA.00083 is a high-performance antenna designed for Beidou Short Message Services, suitable for applications in automotive systems, conventional communications, smart homes, and other related fields. Engineered with precision, the antenna supports three frequency bands—B1, L, and S—at 1561 MHz, 1614 MHz, and 2491 MHz respectively, ensuring reliable signal transmission and reception. It features a nominal impedance of 50 ohms and excellent voltage standing wave ratio (VSWR) performance, with typical values below 1.5 across all bands. The antenna delivers robust gain characteristics, reaching up to 5.74 dBi in the B1 band, making it ideal for high-precision positioning and short-message communication scenarios.

Constructed with mechanical durability in mind, the antenna adheres to strict dimensional specifications and is equipped with an MCX connector for flexible installation. It operates stably within a temperature range of -20°C to +60°C, suitable for various environmental conditions. The packaging follows standardized requirements, including clear labeling and protective materials to ensure product integrity during transportation
