dsp - spe - 17 - 8 - 033 /a/ic p pa ge 2 of 19 1. introduction the dcp.5900 is a 25 * 25 *4 mm embedded p tfe hf patch dsrc (dedicated short range communications) antenna . i t is a hig h performance compact 7 dbi directional antenna design ed to operat e at 5 850 - 5925 mhz for dsrc systems . the antenna has been designed to be circularly polarized to enable a more stable system sig nal strength on moving vehicles where orientation is constantly changing. dsrc is the communications media of choice for active safety v2v/v2x (vehicle - to - vehicle and vehicle - to - other) systems . p rimarily a llocated for vehicle safety applications , dsrc supports high speed, low latency, short - range, v2v/v2x wireless co mmunications. the dcp.5900 ptfe patch antenna is mounted via pin and double - sided adhesive. t h e double - sided a d hesive on the bottom of the patch helps to keep it in place while undergoing mounting. this antenna has been tuned for a center position on a 70 *7 0mm ground and features world leading efficiency at 78 %, and an a xial r atio of approximately 2 db . for further optimization to customer specific device environme nts where positioning is off center or a different ground plane size is used , a custom tune d pa tch antenna can be supplied, subje c t to nre and moq. contact your regional taoglas office for this and for support to integrate and test this antenna performance in your device.
