UGPCB’s 2-Layer Halogen-Free Antenna PCB is a high-performance, environmentally conscious printed circuit board solution engineered specifically for RF circuit design. It is more than a signal carrier; it is a critical component for optimizing antenna efficiency, ensuring precise impedance matching, and enhancing overall device reliability. With deep expertise in high-frequency Projeto de PCB, we deliver a complete PCB to PCBA solution through stringent process controls and meticulous material selection.

In-Depth Analysis: From Materials to Structure

1. Product Definition

A 2-layer halogen-free antenna PCB is a double-sided circuit board dedicated to RF antenna circuitry. Its defining characteristic is the use of an environmentally friendly substrate free from halogens (chlorine, bromo). This makes it compliant with international directives like RoHS while meeting stringent RF performance requirements, making it particularly suitable for consumer electronics and export-oriented products.

2. Core Materials & Electrical Properties

• Substrate Material: Premium Halogen-Free FR-4 laminate. This material emits very low levels of toxic gases when combusted, offering enhanced safety and environmental benefits.

• Constante dielétrica (Dk): A stable Dk value of 4.2. This is a critical parameter for antenna PCB projeto. A stable Dk ensures consistent signal propagation velocity, forming the foundation for predictable antenna impedance control and performance.

• Copper Weight: Base copper of 0.5 OZ, finished copper thickness of 1 OZ (35μm). The thickened copper layer helps reduce conductor loss and improves antenna radiation efficiency.

• Acabamento superficial: Imersão Ouro (CONCORDAR). Provides excellent solderability, superior oxidation resistance, and a flat surface for antenna contact points or solder pads, making it ideal for the PCBA and SMT assembly process.

3. Projeto Estrutural & Key Parameters

• Contagem de camadas & Grossura: 2-layer construction with a standard finished board thickness of 0.8mm, ideal for wireless modules and compact devices.

• Precisão de linha: Minimum trace/space capability of 12mil/12mil. We maintain strict tolerances to ensure precise routing control, which is essential for accurate 50Ω microstrip transmission line design. This directly impacts antenna performance metrics like return loss and VSWR.

• Solder Mask Options: Standard green or white solder mask. White mask is especially beneficial for laser marking and high-end product identification.

Design Essentials & Princípio Operacional

Key Design Considerations:

• Correspondência de Impedância: Utilizing the stable Dk (4.2) and precise trace width control (12mil), designers can calculate or simulate exact 50Ω microstrip lines for perfect impedance matching between the antenna and the RF front-end.

• Grounding Strategy: A well-planned ground plane (GND) provides a complete return path for RF signals, minimizing interference and radiation loss.

• Layout Isolation: Physically and spatially isolating the antenna section from other high-speed digital circuits (por exemplo, MCU, Conversores DC-DC) to prevent noise coupling.

Princípio Operacional:

The copper traces on the antenna PCB are designed into specific geometries (por exemplo, Inverted-F Antenna, meander line antenna). When an RF signal travels from the chip through a matching network to the antenna, these traces convert the electrical signal into electromagnetic waves for radiation (transmit mode) or convert incoming electromagnetic waves into electrical signals (receive mode). The efficiency of this process is highly dependent on the dielectric stability of the PCB laminate and the precision of the trace fabrication.

Características & Advantages

• Stable High-Frequency RF Performance: Consistent Dk (4.2) and strict trace tolerances ensure reliable, repeatable antenna performance across production batches.
