Abstract
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.
Claims20
An apparatus comprising:
- one or more patch antennas, including a first patch antenna comprising a first dielectric substrate having, on a first planar side, a first radiator body in connection with a first set of feedlines and, on a second planar side, a reflector ground plane;
- and
- a patch array antenna coupled to the first patch antenna to form a stacked structure, wherein the patch array antenna comprises a second dielectric substrate having, on a first planar side, a second radiator body comprising a plurality of distinct radiator body elements in connection with a second set of feedlines and, on the second planar side, the first patch antenna.
A system comprising:
- a microelectronic package;
- and
- a stacked patch antenna disposed within the microelectronic package, wherein the stacked patch antenna disposed comprises:
- one or more patch antennas, including a first patch antenna comprising a first dielectric substrate having, on a first planar side, a first radiator body in connection with a first set of feedlines and, on a second planar side, a reflector ground plane;
- and
- a patch array antenna coupled to the first patch antenna to form a stacked structure, wherein the patch array antenna comprises a second dielectric substrate having, on a first planar side, a second radiator body comprising a plurality of distinct radiator body elements in connection with a second set of feedlines and, on the second planar side, the first patch antenna.
A method of operating a stacked patch antenna, the method comprising:
- directing a first set of electrical signal associated with a first set of frequency bands to, and from, a first patch antenna comprising a first dielectric substrate having, on a first planar side, a first radiator body in connection with a first set of feedlines and, on a second planar side, a reflector ground plane;
- and
- directing a second set of electrical signal associated with a second set of frequency bands to, and from, a patch array antenna coupled to the first patch antenna, wherein the patch array antenna is coupled to the first patch antenna to form a stacked structure, and wherein the patch array antenna comprises a second dielectric substrate having, on a first planar side, a second radiator body comprising a plurality of distinct radiator body elements in connection with a second set of feedlines and, on the second planar side, the first patch antenna.
