In the world of real-time kinematic (RTK) positioning, where split-second accuracy defines operational success, the Passive RTK GPS Ceramic Antenna emerges as a compact yet powerful solution. Engineered with a focus on reliability and efficiency, this antenna is tailored to meet the demands of applications ranging from precision agriculture and drone navigation to surveying and autonomous systems, delivering consistent performance in even the most challenging environments.

At its core, the antenna features a Pin Feed (Passive) design, eliminating the need for external power sources and simplifying integration into space-constrained setups. This passive architecture ensures low power consumption, making it ideal for battery-operated devices such as portable RTK receivers and unmanned aerial vehicles (UAVs), where energy efficiency is paramount. The use of a Ceramic Patch Antenna material further enhances its performance: ceramic’s high dielectric constant allows for a compact form factor without sacrificing signal reception, ensuring stable performance across a wide range of frequencies.

Frequency versatility is a key strength of this antenna, with support for critical GNSS bands including GPS L1, GPS L5, BeiDou B1, and GLONASS G1. This multi-constellation coverage ensures robust signal reception, even in areas with partial satellite visibility, such as urban canyons or dense vegetation. Whether operating in open fields or complex terrains, the antenna’s ability to tap into multiple satellite systems minimizes positioning errors, making it a reliable choice for RTK applications that demand centimeter-level accuracy.

The antenna’s compact dimensions—35356.12 mm—and lightweight design (26g) make it highly adaptable to diverse mounting scenarios. Its small footprint allows for easy integration into drones, rovers, or handheld devices, while its low weight ensures minimal impact on vehicle balance or payload capacity. Complemented by a 70*70 mm ground plane, the antenna achieves optimal signal stability, reducing the effects of unwanted interference and ensuring consistent performance in dynamic environments.

Performance metrics underscore the antenna’s precision. With a peak gain of up to 4.03 dBi and efficiency reaching 79.93%, it effectively captures and amplifies weak signals, ensuring reliable communication with satellites even at low elevations. The RHCP (Right-Hand Circular Polarization) further enhances signal integrity by mitigating multipath interference—common in reflective environments—while the omnidirectional radiation pattern ensures 360-degree signal coverage, eliminating blind spots.

Designed to withstand harsh conditions, the antenna operates flawlessly within a temperature range of -40°C to +85°C, making it suitable for deployment in extreme climates, from frozen tundras to scorching deserts. Its VSWR (Voltage Standing Wave Ratio) of 2:1 to 4:1 (depending on the band) ensures efficient power transfer, minimizing signal loss and maximizing receiver sensitivity.

the Passive RTK GPS Ceramic Antenna combines compact design, multi-band compatibility, and robust performance to deliver reliable, high-accuracy positioning for a wide range of RTK applications. Whether powering agricultural drones, surveying equipment, or autonomous vehicles, it stands as a testament to engineering efficiency—proving that precision and portability can indeed go hand in hand.
