The DCP.5900 from Taoglas is a ceramic patch antenna designed for emerging V2V (vehicle-to-vehicle) and V2X (vehicle-to-anything) applications. It supports the latest DSRC (dedicated short-range communications) technology, which enables two-way, short- to medium-range wireless communications and is critical for active safety applications.
The antenna operates from 5850 MHz to 5925 MHz, fully covering the spectrum allocated for DSRC by the US Federal Communications Commission (FCC) and the European Telecommunications Standards Institute (ETSI) Using these frequencies, DSRC will enable cars to communicate with each other and alert drivers to roadside hazards ahead.
Critical for makers of vehicle safety devices or any V2V or V2X application, this antenna supports high speed and low latency with short-range wireless communication. “For DSRC devices, antenna performance is essential – these devices need to work at all times, even in the toughest RF environments. With safety applications there’s no room for error,” says Dermot O’Shea, Taoglas’ joint CEO. “The DCP.5900 has an efficiency of 75% and works in rugged environments, even providing continuing connectivity in harsh weather conditions such as subzero or very high temperatures.”
The patch antenna is mounted via pin and double-sided adhesive. Even though it measures only 12 x 12 mm, it exhibits a peak gain of 5,89 dBi. The antenna is circularly polarised which means device manufacturers do not have to worry about connecting with other devices such as cars or traffic light systems. The DCP.5900 allows OEMs to transmit and receive more effectively with antennas of varying polarisation and characteristics, important in a mobile environment where it’s not known how the other antennas will be installed.
