Abstract
The antenna module includes a first substrate and a second substrate on each of which a radiating element is arranged, a third substrate, and a switch circuit. An RFIC for supplying a radio frequency signal to the first substrate and the second substrate is arranged on the third substrate. The switch circuit is configured to change over a connection between the RFIC and the radiating element on the first substrate and a connection between the RFIC and the radiating element on the second substrate.
Claims18
An antenna assembly, comprising:
- a first substrate and a first radiating element arranged on the first substrate;
- a second substrate and a second radiating element arranged on the second substrate;
- a third substrate having a feed circuit that supplies a radio frequency signal to the first substrate and the second substrate is arranged;
- a connection member that interconnects the first substrate, the second substrate, and the third substrate, and is configured to transfer a first radio frequency signal between the feed circuit and the first radiating element and between the feed circuit and the second radiating element;
- and
- a switch circuit configured to controllably change over a connection between the feed circuit and the first radiating element and a connection between the feed circuit and the second radiating element.
