Specification Part No. : DCP.5900.12.4.A.02 Description : 6dBi 5.9GHz 12mm DSRC/C-V2X Ceramic Patch Antenna Features : 5.9GHz C-V2X Ceramic Patch Antenna 5850MHz to 5925MHz Peak Gain: 5.89dBi Efficiency: >75% Dimensions: 12*12*4mm Manufactured in an IATF16949 Approved Facility RoHS & REACH Compliant sdfghjyfguyfluyfgoiuytdSPE-15-8-071-D Page 1 of 16 1. Introduction The DCP.5900 is a world-leading C-V2X (& DSRC) Antenna with up to 75% efficiency. It 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 C-V2X systems. It is mounted via pin and double-sided adhesive and has been tuned for a center position on a 70mm *70mm ground plane. 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-center or a different ground-plane size, a custom-tuned patch antenna can be supplied, subject to NRE and MOQ. C-V2X is the communications medium of choice for active safety V2V/V2X (Vehicleto-Vehicle and Vehicle-to-Other) systems. Primarily allocated for vehicle safety applications, C-V2X supports high-speed, low-latency, short-range, V2V/V2X wireless communications.

Application Note The DCP.5900 C-V2X 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. Return Loss Antenna performance on different ground plane sizes is shown below. (The antenna locaton is at the center of ground plane) sdfghjyfguyfluyfgoiuytdSPE-15-8-071-D Page 14 of 16 Return Loss Taoglas makes no warranties based on the accuracy or completeness of the contents of this document and reserves the right to make changes to specifications and product descriptions at any time without notice.
