Shaped Anti-Jamming GNSS Antenna PT023

Overview

The Shaped Anti-Jamming GNSS Antenna PT023 uses multiple array elements plus amplitude and phase to achieve spatial radiation shaping. Additionally, it incorporates advanced multi-level filtering to achieve exceptional out-of-band noise power suppression and is designed to withstand high-power conditions without damage. This versatile antenna is suitable for various devices facing the mentioned scenarios, including UAV, aviation equipment, vehicle systems, and marine applications.

Key Features

Multi-Element Synthesis for High-Gain Energy Coverage

By combining various antenna elements with different feed amplitudes and phases, this antenna achieves energy coverage in spatial domains.

Resilience Against High-Power Low-Angle Interference at the Same Frequency

Utilizing shaping techniques, it effectively attenuates energy below low-angle domains (such as near-ground) to mitigate interference from signals at the same frequency

Strong Suppression of Multipath Effects

Leveraging low-angle reception with shaping techniques, it reduces the impact of non-line-of-sight electromagnetic waves. Additionally, a polarization inhibitor at the antenna base further suppresses reception of fully polarized non-line-of-sight waves

High-Power Burnout Resistance

Equipped with burnout-resistant amplitude-limiting devices, ensuring durability even under high-power conditions

Advanced Pre-Filtering for Out-of-Band Noise Suppression

Combining spatial and radio frequency filtering to attenuate out-of-band noise signals effectively

Ultra-Wideband Capability for High-Precision Positioning and Stable Signal Reception

The antenna design features multiple spiral arms and a half-wavelength approach, achieving wideband reception

Flexible Mounting Options: Upward and Downward

Considering diverse scenarios, the product can be securely fixed either upward or downward using screws, providing flexibility in installation.
