The exemplified systems and methods provides a low-profile stacked patch multi-frequency antenna (e.g., a dual-frequency antenna). A design is disclosed which is configured to operate at the 5.9-GHz band (e.g., for Dedicated Short Range Communications) and the 28-GHz band (e.g., for 5G communications). With a low-profile, the exemplified systems and methods can be integrated into existing microelectronic packaging systems as well as readily integrated into communication systems having smaller form factor.
