Abstract:
An antenna for radiating an electromagnetic field includes a ground plane, a first dielectric layer disposed on the ground plane, and a second dielectric layer disposed on the first dielectric layer. The antenna includes at least one feeding element embedded in the first dielectric layer and a radiating element extending from the feeding element. The radiating element is embedded within the first dielectric layer adjacent to the second dielectric layer. A beam steering element is embedded in the second dielectric layer and electromagnetically coupled to the radiating element. Embedding the beam steering element in the second dielectric layer and electromagnetically coupling the beam steering element to the radiating element allows the antenna to tilt a radiation beam to overcome a roof obstruction from a vehicle while maintaining acceptable gain, polarization, and directional properties for SDARS applications.
