Description
Data Sheet

This product is a 2-layer halogen‑free (HF) antenna PCB. RF antenna circuits impose extremely tight dimensional tolerance requirements for high-frequency signal traces. Maxipcb possesses rich mature manufacturing experience, enabling precise process control to fully meet the strict precision and electrical performance demands of RF antenna boards.

A PCB antenna is a planar integrated radiation structure designed for wireless signal transceiving. Most PCB antenna designs adopt omnidirectional radiation characteristics. Different from conventional external antennas, it is directly patterned on the PCB surface to achieve integrated planar layout.

Antenna PCB

Industry Application

Antenna PCBs have become core components for signal transceiving in wireless communication devices and are widely deployed in the telecommunications industry. Driven by 5G network popularization and the rapid expansion of the Internet of Things (IoT), nearly all smart electronic terminals require built-in antenna PCBs for wireless data interaction, further boosting market demand for high-frequency antenna substrates.

RF antenna design and high-frequency layout are the two decisive factors that determine the overall performance of wireless equipment. Even with identical RF main chips and peripheral circuits, different antenna routing schemes and layout strategies will lead to completely distinct radio frequency indexes. The key performance gap stems from design specification control, high-frequency impedance matching, and detail optimization in the development phase.

Compact integrated PCB antennas are widely adopted in commercial and consumer products within ISM frequency bands such as 2.4 GHz and 915 MHz. As a built-in wireless solution, the antenna trace is directly fabricated on the PCB, effectively reducing product size and structural costs.

Cost optimized planar F-antenna PCB

Use the following formula to calculate the width of the antenna

Design of F-type antenna

The length of the meandering inverted-F antenna or mifa needs to be adjusted to consider the radiation impedance and frequency of the antenna. The tip and length of the mifa antenna are determined by the thickness of the PCB as follows:

Planar Antenna Design & Material Selection

Cost-Effective Planar F-Antenna Design

The trace width of planar F-antennas can be calculated through professional high-frequency formulas to realize impedance matching and cost optimization.

For meander inverted-F antennas (MIFA), overall electrical length must be dynamically adjusted according to target radiation impedance and operating frequency. PCB core thickness is a critical parameter that directly defines antenna terminal size and bending dimension, serving as the core basis for MIFA structural parameter design.

High-Frequency Base Material Selection

Conventional standard FR-4 laminates exhibit poor dielectric stability and high signal loss under high-frequency conditions, making them unsuitable for high-performance antenna applications.

To ensure low loss, stable dielectric constant and excellent RF performance, antenna PCBs adopt professional high-frequency low-loss materials, including:

Rogers, Teflon, Arlon, Taconic, Nelco, FR5, Dupont and Isola series high-frequency substrates.
