Antenna Description


Mono-Flexi Cellular/ 4G LTE/3G/2G Left-Hand Feed Flexible Polymer Self-Adhesive Antenna


Advanced Technology Powering The World's Smallest Flexible Antenna Unlocking Global Communication

2J Antennas is introducing the world’s smallest high performance Left-Hand Feed Cellular/ LTE Flexible Polymer Self-Adhesive Mount Antenna (2JF1424P) to the new “Mono-Flexi '' series. This highly efficient antenna introduces a new cable bridging between radiation elements and ground plane extension, making it ideal for small device integration into PCB or cellular devices with complicated size restrictions. This creates a lower resonance and optimizes tuning while keeping the antenna size to a minimum with maximum efficiency, especially across low frequency bands.

Suggested applications include:

- Cellular Mobile Voice / Video 
- Smartphones 
- Mobile HD/ TV 
- Wearables/ Consumer Electronics 
- Laptops/ Tablets
- Mobile Internet / Data

2JF1424P is compatible with 4G LTE, 3G and 2G standards, covering 698 MHz – 2700 MHz frequencies. With peak gains up to ~4.1 dBi, this antenna maintains excellent maximum efficiency of ~69% while offering constant reliable connectivity. This antenna is the newest solution for high voice, data, and internet connectivity necessary for IoT and device to device quality communications.

Installation / Environmental

The compact 2JF1424P, measuring only 40 x 20 x 0.2 mm, is manufactured with high quality flexible polymer material and has the smallest antenna footprint on the market without sacrificing performance. Designed with a 3M self-adhesive mount allows for versatile in device or PCB installations where size restrictions are challenging. This flexible antenna will fit any positioning requirements as it can be integrated upwards, flat, downwards and with intermediate angles. Adding a short cable between the antenna and the ground plane extension allows us to minimize the antenna size while maximizing the electrical length of the collinear and non-collinear radiated elements. The antenna is left hand fed allowing for simple antenna integration and some PCB cellular modules which may have the signal pad on the right side or left side. (Please see product 2JF1424Pa for the Cellular/LTE right hand feed antenna option). This new technology makes this antenna the future solution for high demand smaller devices and antenna miniaturization.

2JF1424P comes with a U.FL connector and a perfectly tuned 38mm long 1.37mm Mini-Coax cable. We offer a wide range of alternative connectors and cables to meet any customization needs.

All our products are designed and manufactured without hazardous materials while maintaining full REACH and RoHS compliance.
