Ceramic patch antennas target emerging V2V and V2X applications
Ahead of the market, the DCP.5900 supports the latest communications technology for vehicles — DSRC (dedicated short-range communications). This system 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 U.S. 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.
“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,” said 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 DCP.5900 ceramic patch antenna is mounted via pin and double-sided adhesive. Even though the miniature antenna is only 12- x 12-mm it exhibits a peak gain of 5.89 dBi and over 75% efficiency. The antenna is circularly polarized which means device manufacturers do not have to worry about connecting with other devices such as cars or traffic light systems. The antenna allows OEMs to transmit and receive more effectively with antennas of varying polarization and characteristics, important in a mobile environment where it’s not known how the other antennas will be installed.
