Abstract
This application provides an antenna and an array antenna. The antenna in this application includes a first radiating element and a second radiating element, where four dipoles enclose to form the first radiating element, and the second radiating element is a radiating element disposed on an inner side of the first radiating element. The first radiating element is configured to support a transmit frequency band, and the second radiating element is configured to support a receive frequency band; or the first radiating element is configured to support a receive frequency band, and the second radiating element is configured to support a transmit frequency band.
Claims17
An antenna, comprising:
- a first radiating element;
- and
- a second radiating element,
- wherein:
- the first radiating element comprises four dipoles enclosing the second radiating element in a plan view, and
- the second radiating element is disposed on an inner side of the first radiating element, and
- wherein:
- the first radiating element is configured to support a transmit frequency band, and the second radiating element is configured to support a receive frequency band, or
- the first radiating element is configured to support the receive frequency band, and the second radiating element is configured to support the transmit frequency band;
- and
- a third radiating element disposed on an outer side of the first radiating element,
- wherein:

- the second radiating element and the third radiating element each are configured to support either of a first receive frequency band or a second receive frequency band, and
- the second radiating element and the third radiating element support different frequency bands.
An array antenna, comprising a plurality of antennas, wherein each antenna of the plurality of antennas respectively comprises:
- a first radiating element;
- and
- a second radiating element,
- wherein:
- the first radiating element comprises four dipoles enclosing the second radiating element in a plan view, and
- the second radiating element is disposed on an inner side of the first radiating element;
- and
- wherein, for each antenna of the plurality of antennas:
- the first radiating element of the respective antenna is configured to support a transmit frequency band, and the second radiating element of the respective antenna is configured to support a receive frequency band, or
- the first radiating element of the respective antenna is configured to support the receive frequency band, and the second radiating element of the respective antenna is configured to support the transmit frequency band;
- and
- a third radiating element, wherein each third radiating element is disposed on an outer side of the respective corresponding first radiating element,
- wherein:
- each first radiating element is configured to support a first transmit frequency band and a second transmit frequency band,
- each second radiating element and each third radiating element are configured to support either of a first receive frequency band or a second receive frequency band, and
- the second radiating elements and the third radiating elements support different frequency bands.
