Abstract
Disclosed is a phased array antenna including a first component layer with a plurality of antenna elements supported by at least one antenna substrate. A second component layer underlies the first component layer and includes a plurality of RF integrated circuit (RFIC) chips each comprising at least one amplifier, and each being RF coupled to at least one of the antenna elements through the at least one antenna substrate. A third component layer underlies the second component layer and comprises a plurality of phase shifters electrically coupled to the plurality of amplifiers, for steering a beam formed by the plurality of antenna elements.
Claims24
A phased array antenna comprising:
- a first component layer comprising a plurality of antenna elements supported by at least one antenna substrate;
- a second component layer, underlying the first component layer, comprising a plurality of radio frequency (RF) integrated circuit (RFIC) chips each comprising at least one amplifier, and each being RF coupled to at least one of the plurality of antenna elements through the at least one antenna substrate;
- and
- a third component layer, underlying the second component layer, comprising a plurality of phase shifters electrically coupled to the plurality of amplifiers, for steering a beam formed by the plurality of antenna elements.
A phased array antenna comprising:
- a plurality of antenna element systems in a package, AESiPs, each forming a subarray of the phased array antenna and each comprising:
- a first component layer comprising a plurality of antenna elements supported by at least one antenna substrate;
- a second component layer, underlying the first component layer, comprising a plurality of radio frequency (RF) integrated circuit (RFIC) chips each comprising at least one amplifier, and each being RF coupled to at least one of the plurality of antenna elements through the at least one antenna substrate;
- and
- a third component layer, underlying the second component layer, comprising a plurality of phase shifters electrically coupled to the plurality of amplifiers, for steering a beam formed by the plurality of antenna elements;
- and
- a combiner/divider configured to combine a plurality of receive path signals derived from signals received and phase shifted by the plurality of phase shifters of the plurality of AESiPs to provide a composite receive path signal, and/or to divide an input transmit path signal into a plurality of divided transmit path signals which are output to the plurality of phase shifters.
