Antenna Description

2J0202-C638

Ultra compact High Gain Antenna Solution for Automotive IoT and Wireless Connectivity

We are pleased to offer the ultra-small 2.4/5.0 GHz WiFi ISM Monopole Antenna (2J0202-C638) that brings powerful long and short-range connectivity to automotive IoT applications. 2J0202-C638 is designed for WiFi, BT, ZigBee and ISM standards and for wireless technology that operates within 2410-2490 MHz and 4920-5925 MHz frequencies. This unique antenna comes with Fakra click connector technology that is primarily used in automotive applications where installation space is restricted. In most cases, Cellular/GNSS antennas are installed outside of the vehicle and WiFi/Bluetooth requires installation inside the vehicle. The Fakra Connector Antenna reduces cost and offers simple installation where the antenna can connect directly to telematic units.

Suggested applications include:

- Vehicle to Device Connection
- Vehicle to Smart Home
- Vehicle Tracking Data (Telematics)

  • Location
  • Speed
  • Fuel Consumption
  • Vehicle status

- Automotive IoT Connectivity

 

The 2.4 GHz and 5.0 GHz bands combine long-range coverage with short-range high speed data transmissions with up to 2.6 dBi peak gains. WiFi/Bluetooth allows wireless connection between a mobile device and a vehicle or smart home. This antenna is also suitable for automotive R&D testing equipment that transfers real time data. Designed with an omni-directional radiation pattern, this efficient antenna gives 360-degree consistent signal range. 

Installation and Durability

The ultra-small 2J0202-C638 measures only Ø 12.5 × 44.5 mm (including Fakra connector) and comes with a Fakra-I-Beige-Female connector mount. Fakra connectors are the leading choice for automotive applications due to their resistance to vibration and secure latch and click mechanism. The antenna housing is manufactured with durable ASA material that is resistant to temperatures between -40C to +85C ideal for outdoor applications. 

As with all ground plane dependent monopole antennas, we recommend perpendicular installation on a conductive or metal surface. Please contact our highly skilled engineers for any installation support, customization, or antenna selection needs. 

All our products are designed with the environment in mind and manufactured without hazardous materials with full REACH and RoHS compliance.
