NFC Antenna For Car Keyless Entry System

Overview

This in-vehicle NFC (Near Field Communication) antenna has an operating frequency of 13.56MHz and is a high-performance antenna designed for vehicle communication systems. It has a low standing wave ratio (V.S.W.R. <2.0) and a stable impedance (50±3Ω), ensuring efficient and stable communication performance. The NFC antenna communicates with other devices contactlessly through electromagnetic fields, providing a convenient interactive experience for vehicles.

Key Features

• Efficient communication

The operating frequency is 13.56MHz, which complies with the NFC standard and ensures high-speed and stable communication performance.

• Low standing wave ratio

V.S.W.R.<2.0, which reduces signal reflection and improves communication efficiency.

• Stable impedance

The impedance is controlled within the range of 50±3Ω, which ensures the stability and consistency of signal transmission.

• Strong adaptability

The antenna design takes into account space constraints and efficiency, and is suitable for a variety of vehicle models and communication systems.
