As IoT terminal devices trend toward miniaturization and integration, antennas— the "antennae" of wireless communication— are critical for flexibility and reliability. To meet diverse internal device structure needs, Chengdu Ebyte recently launched two new rubber  antennas: TX433-JKR-19 and TX2400-JKS-20. Targeting mainstream low-band and high-speed high-band applications respectively, these new products offer more flexible connectivity options, further enhancing Ebyte’s rubber  antenna product line.

Product Focus: Precise Positioning with Distinct Features

Though both belong to the rubber  antenna category, the two models complement each other in target frequency bands and connectivity methods, addressing specific scenario challenges.

  1. TX433-JKR-19: Bendable Antenna Optimized for 433MHz

  • Target Frequency: 433MHz, a band with strong penetration and long transmission range, widely used in smart homes, security alarms, remote control, and industrial sensing.

  • Core Features: The "JKR" in its name indicates an SMA-J connector and bendable design. Engineers can adjust the antenna to the optimal position based on internal device space to avoid interference and achieve optimal radiation performance. Its ~19mm height (denoted by "-19") suits space-constrained embedded devices.

  • Advantage: Direct SMA connection ensures secure installation and high reliability, making it ideal for devices requiring stable connectivity.

  1. TX2400-JKS-20: IPEX-Connected Solution for 2.4GHz High-Band Applications

  • Target Frequency: 2.4GHz, the core band for high-speed protocols like Wi-Fi, Bluetooth, and Zigbee.

  • Core Features: "JKS" and "-20" signify an IPEX Gen-1 connector and ~20mm height. The IPEX connector is a board-to-wire interface that links to the mainboard via a feeder cable, ideal for applications needing antennas to be placed away from mainboard interference or inside device casings.

  • Advantage: Extremely flexible installation, efficiently utilizing irregular internal casing space— a key component for device miniaturization and signal optimization.

Core Advantages: Compact, Flexible, High-Performance

  1. Omnidirectional Radiation for Full Coverage
    Both antennas use omnidirectional radiation, ensuring 360° uniform signal coverage in the horizontal plane. This guarantees stable communication links for mobile terminals or node devices regardless of orientation.

  2. Compact Design for Easy Integration
    Rubber  antennas are inherently small and lightweight. The compact design of TX433-JKR-19 and TX2400-JKS-20 allows easy embedding into narrow device cavities, greatly simplifying product structural design.

  3. Specialized Connectors for Reliable Connectivity
    Ebyte offers tailored connector options: the SMA-connected TX433-JKR-19 for scenarios requiring robust links, and the IPEX-connected TX2400-JKS-20 for flexible wiring. This differentiated design reflects Ebyte’s deep understanding of customers’ practical engineering needs.

Typical Application Scenarios

  • TX433-JKR-19 (SMA Connector): Industrial wireless sensor nodes, smart home controllers (e.g., curtain motors, gateways), data acquisition units (DTUs), and 433MHz devices requiring direct SMA connections.

  • TX2400-JKS-20 (IPEX Connector): Smart appliances with built-in Wi-Fi/Bluetooth, portable medical devices, drone video transmission modules, and 2.4GHz devices with strict internal space requirements.

The launch of Ebyte’s TX433-JKR-19 and TX2400-JKS-20 is more than an expansion of its rubber  antenna line—it is a precise response to the diverse connectivity needs of IoT devices. By offering options spanning low to high frequencies, and SMA direct connections to IPEX flexible links, Ebyte empowers device developers to tackle design challenges, optimize wireless performance, and accelerate the deployment of innovative IoT applications.
