Lightweight Antenna
Engineered for space-constrained smart devices, our lightweight antenna series delivers exceptional RF performance within an ultra-compact form factor, enabling seamless connectivity for your IoT modules.
1. Lightweight IoT Antenna Series - Sub-Product Line Filter
Use the following table to understand our naming conventions and filter the core sub-series based on your physical design constraints.
| Sub-Series Code | Antenna Type | Form Factor & Material | Installation / Interface | Best Application Scenarios |
|---|---|---|---|---|
| FPC | Flexible Printed Circuit | Ultra-thin, bendable, lightweight tape | IPEX-1 / IPEX-3 / IPX | Internal mounting on curved surfaces, compact smart home devices. |
| PCB | Printed Circuit Board | Rigid board, compact size | IPEX / SMA-J | Internal flat mounting, routers, gateways requiring stable structural gain. |
| TH | Spring Antenna | Coiled copper spring, highly compact | PCB Solder (Through-hole) | Ultra-low cost, directly soldered to module boards (e.g., smart hotel locks). |
| JK / JKD | Rubber / Foldable Antenna | TPEE material, straight or 90-degree foldable | SMA-J (Male thread, inner pin) | External cabinet mounting, modems, adaptable signal orientation. |
| JZ / JZG | Glue Stick / Rubber Rod | Straight, sturdy cylinder shape | SMA-J | Standard external communication modules, durable outdoor/industrial use. |
| JW | Elbow Rubber Antenna | Fixed 90-degree right angle | SMA-J | Wall-mounted terminals where straight antennas take up too much vertical space. |
| JZLW | Screw Fixed Rubber Rod | High gain, screw-fixed base | IPEX-1 to external rod | Equipment cabinets, logistic fleets, property security bases. |
2. Model Selection by Parameters (Frequency & Form Factor)
Select your specific product model by matching the operating frequency of your Ebyte IoT module with the required antenna form factor.
| Frequency Band | Recommended FPC/PCB (Internal) | Recommended Rubber (External) | Recommended Spring (Solder) |
|---|---|---|---|
| 170MHz / 230MHz (VHF) | - | TX170-JKD-20, TX230-JK-11 | - |
| 433MHz (UHF, LoRa) | TX433-FPC-5711, TX433-PCB-3207 | TX433-JZ-5, TX433-JKD-20, TX433-JW-5 | TX433-TH-3, SW433-TH32DN |
| 868MHz / 915MHz (LoRaWAN) | TX915-FPC-4510 | TX868-JZ-5, TX915-JK-11, TX868-JZLW-15 | - |
| 2.4GHz / 5.8GHz (Wi-Fi, BLE, Zigbee) | TX2400-FPC-2509, TX2400-PCB-4811 | TX2400-JKD-20, TX2400-JZ-3, TX2400-JW-3 | - |
| LTE / GSM / NB-IoT (Cellular) | TX4G-FPC-4015, TX4G-PCB-125014 | TXGN-JKD-20, TXGN-JW-5 | - |
3. Quick Selection Guide
- Step 1: Match the Frequency. The antenna's frequency (e.g., 433MHz) must strictly match your Ebyte wireless module (e.g., E220-400T22S). Mismatched frequencies will result in high SWR and drastically reduced range.
- Step 2: Evaluate Spatial Constraints. For ultra-compact, enclosed devices (like smart wearables or internal sensors), choose FPC (-FPC-) or Spring (-TH-) antennas. For gateways or routers with external housing, choose Rubber (-JK-/-JZ-) antennas.
- Step 3: Confirm the Interface. Ensure the antenna interface matches your module or board. Use IPEX (IPX) for internal RF connectors, PCB Solder for direct integration, and SMA-J for external screw-on connections.
- Step 4: Check Gain Requirements. Higher dBi (e.g., 5dBi) offers longer range but a flatter, more directional signal. Lower dBi (e.g., 2dBi) offers a wider, more uniform omnidirectional coverage pattern.
4. Frequently Asked Questions (FAQ)
Q1: How do I choose between an FPC and a PCB antenna for my Ebyte LoRa module?
A: Both are internal antennas, but FPC (Flexible Printed Circuit) is bendable and comes with adhesive backing, making it perfect for curved housings. PCB (Printed Circuit Board) antennas are rigid and offer slightly better structural stability for the signal pattern. If space is tightly confined and non-flat, choose FPC.
Q2: What is the benefit of a spring antenna (TH series) for modules like the E07 or E220 series?
A: Spring antennas like the TX433-TH-3 are incredibly cost-effective and space-saving. They solder directly onto the main PCB board alongside your E07 or E220 module, eliminating the need for IPEX cables or SMA connectors. They are ideal for high-volume, low-cost smart devices like smart hotel locks or remote controls.
Q3: Can I use a 2.4GHz Wi-Fi antenna for a 2.4GHz ZigBee or BLE module?
A: Yes. The 2.4GHz frequency band is shared among Wi-Fi, Bluetooth (BLE), and ZigBee. Any antenna in our 2.4GHz series (such as TX2400-JKD-20 or TX2400-FPC-2509) will work perfectly with Ebyte's BLE or ZigBee modules, provided the interface matches.
Q4: My Ebyte module has an IPEX connector, but I need the antenna outside the metal cabinet. What should I do?
A: You cannot place an FPC/PCB antenna inside a sealed metal cabinet, as the metal blocks RF signals. You should purchase an IPEX-to-SMA adapter cable. Connect the IPEX end to your module, mount the SMA female end to a hole drilled in your cabinet, and screw on a Rubber Antenna (e.g., the -JK- or -JZ- series) on the outside.
