Frequently Asked Questions

Q: What wireless protocols is this 2.4G ceramic patch antenna compatible with?

A: This ceramic patch antenna operates in the 2400–2500 MHz frequency range, making it fully compatible with WiFi (802.11 b/g/n), ZigBee, Bluetooth (Classic and BLE), and virtually any 2.4 GHz IoT wireless module or microcontroller platform such as ESP32, ESP8266, nRF24L01, and similar devices.

Q: Can I get a custom cable length or connector type for this antenna?

A: Yes! Custom cable lengths and connector types (such as SMA, IPEX/U.FL, RP-SMA, etc.) are available. Please contact us directly with your specifications, and we will accommodate bulk or custom orders with fast turnaround.

Q: What is the impedance of this ceramic patch antenna and why does it matter?

A: The antenna has a standard 50 Ohm impedance, which matches the vast majority of RF modules, transceivers, and evaluation boards. Matching impedance ensures minimal signal loss and optimal power transfer between the antenna and your wireless module.

Q: How do I mount this patch antenna to my PCB or enclosure?

A: The patch antenna is a surface-mount design (25 × 25 × 4 mm) that can be adhered directly to a PCB, plastic enclosure, or any flat surface. No assembly is required — simply connect the cable to your module's RF port and it is ready to use.
