Abstract
An antenna module includes a substrate that includes a first dielectric layer and a second dielectric layer with a dielectric constant different from a dielectric constant of the first dielectric layer, a first antenna that is disposed on or in the first dielectric layer and transmits and receives a signal in a first frequency band, a second antenna that is disposed on or in the second dielectric layer and transmits and receives a signal in a second frequency band which is a lower frequency band than the first frequency band, and a radio frequency circuit that is disposed on or in the substrate and is electrically connected to the first antenna.
Claims17
An antenna module comprising:
- a substrate that includes a first dielectric layer with a first dielectric constant and a second dielectric layer with a second dielectric constant, wherein the second dielectric constant is different from the first dielectric constant;
- a first antenna that is disposed on or in the first dielectric layer and that transmits and receives a signal in a first frequency band;
- a second antenna that is disposed on or in the second dielectric layer and that transmits and receives a signal in a second frequency band which is a lower frequency band than the first frequency band;
- a radio frequency circuit that is disposed on or in the substrate, and that is electrically connected to the first antenna;
- and
- a ground layer that is disposed between the first antenna and the second antenna, the first antenna and the second antenna opposing to each other,
- at least part of the first antenna is disposed in a region overlapping with the second antenna in a plan view.
