1.Introduction
The DCP.5900 is a 12*12*4 mm embedded ceramic DSRC Patch antenna. It is a high
performance compact 6dBi directional antenna designed to operate at 5850 MHz to
5925 MHz for DSRC systems.
DSRC (Dedicated Short Range Communications) is the communications media of
choice for active safety V2V/V2X (Vehicle to Vehicle and Vehicle to Other) systems,
primarily allocated for vehicle safety applications. DSRC supports high speed, low
latency, short- range V2V/V2X wireless communications. The DCP.5900 ceramic patch
antenna is mounted via pin and double-sided adhesive. This antenna has been tuned
for a centre position on a 70mm *70mm ground plane and features world leading
efficiency at 75%.
The polarization has been designed to be circularly polarized to enable a more stable
system signal strength on moving vehicles.
For further optimization to customer specific device environments where positioning is
off centre or a different ground-plane size, a custom tuned patch antenna can be
supplied, subject to NRE and MOQ. Contact your regioinal Taoglas office for this, and
for support to integrate and test this antenna’s performance in your device.

9.Application Note
The DCP.5900 DSRC patch antenna is designed for 70mm*70mm ground plane center.
Taoglas provides the experimental reference below if the antenna isn’t placed at the
center of ground plane. Please refer to the return loss data shown in the graph below.
