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.
