Introduction** The SDDCP.5900.25.10.A.08 is a passive embedded ceramic stacked patch antenna with both SDARS and DSRC capabilities. Using a stacked dual patch assembly for both bands results in the most economical and space-efficient solution for demanding applications requiring both SDARS and DSRC. The patch assembly is easy to integrate with an overall footprint size of just 25x25mm and sits at 10.15mm in height. The SDARS patch at 25mm*25mm is designed for use with Satellite Digital Audio Radio Services (SDARS). It features left-hand circular polarization, low in-band axial ratio, and excellent gain characteristics in the 2320 to 2345 MHz band, making it compatible with the most popular satellite radio services available in many new vehicles. It is extremely efficient with up to 80% efficiency at 2332.5MHz. The DSRC patch at 12mm*12mm is used as the communications medium 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, lowlatency, short-range, V2V/V2X wireless communications. The DSRC patch also has left hand circular polarization and nearly 70% efficiency at 5900MHz. A typical use case would include utilizing the stacked patch in shark fin style external automotive roof mounted antennas. This antenna has been tuned and tested on a 70 x 70 mm ground plane. Custom tuning services can be provided for further optimization to customer-specific device environments. Note that certification of your device and/or the antenna may be required by certain Satellite Radio providers. Further engineering may be needed to meet their requirements.
