The 2.4GHz Built-in PCB Copper Tube Patch Antenna is a compact, high-performance omnidirectional antenna designed for integration into WiFi and Bluetooth network card modules, IoT devices, and wireless communication boards. Operating at 2400–2500 MHz, this antenna delivers stable gain and reliable 360° signal coverage in a minimal footprint, making it the ideal embedded radiating solution for space-constrained PCB layouts.
Engineered with a precision-etched copper tube patch element on FR4/ceramic substrate, the antenna achieves excellent impedance matching (VSWR ≤ 1.5) without external tuning components. The built-in design eliminates the need for external SMA connectors and coaxial cables, reducing BOM cost and simplifying assembly for high-volume production.
Available in multiple form factors—including PCB trace antenna, copper tube helix, and FPC flexible variants—this antenna supports full OEM/ODM customization for frequency, size, connector interface, and gain. Factory-direct pricing with rapid 3–5 day sampling for prototype validation.

Q1: What is the difference between a PCB trace antenna and a copper tube patch antenna?
A PCB trace antenna is etched directly onto the circuit board (zero added cost), while a copper tube patch antenna uses a separate copper element soldered onto the PCB. The copper tube design typically offers 1–2 dB higher gain and better pattern consistency in a slightly larger footprint.
Q2: Can this 2.4 GHz antenna also work for 5 GHz WiFi?
The standard model is optimized for 2400–2500 MHz. For dual-band WiFi (2.4 + 5 GHz), we offer a combined antenna or separate 5 GHz variant. Contact us for dual-band PCB antenna solutions.
Q3: How do I integrate this antenna into my network card module?
For PCB trace designs, we provide Gerber files and layout guidelines. For copper tube/FPC variants, the antenna connects via solder pads or an IPEX (U.FL) connector. Our engineers provide reference layouts and matching network recommendations free of charge.
Q4: What ground plane size is required for optimal performance?
A minimum ground plane of 40×20 mm is recommended for 2.4 GHz PCB antennas. Smaller ground planes may reduce gain by 1–2 dB and shift resonant frequency. We can simulate your specific PCB dimensions to optimize placement.
Q5: Is this antenna suitable for Bluetooth 5.3 and BLE applications?
Yes. The 2400–2500 MHz band fully covers Bluetooth Classic, BLE 5.0/5.3, and BLE Mesh. The omnidirectional pattern ensures reliable short-range connectivity in any device orientation.
Q6: What is the minimum order quantity and lead time?
Stock models ship from 100 pcs within 2–3 days. Custom OEM antennas (specific size, shape, connector) require 1,000+ pcs with 10–15 day bulk lead time. Samples are available in 3–5 days.
Q7: Can you help with antenna matching and VSWR tuning?
Yes. Our RF lab provides complimentary VSWR measurement and matching network design. Share your PCB layout and enclosure dimensions, and we'll deliver optimized matching component values within 48 hours.
