An antenna structure includes a first substrate and a second substrate. The first substrate includes: a semiconductor chip configured to transmit or receive a first radio-frequency (RF) signal; a first ground layer configured to provide ground to the semiconductor chip; and a signal layer arranged on a side of the first substrate opposite to the semiconductor chip and configured to transmit the first RF signal. The second substrate has an antenna array formed of antenna cells, each of the antenna cells including: a first antenna layer configured to radiate second RF signals based on the first RF signal; a second ground layer configured to provide ground to the first antenna layer. The antenna device further includes a plurality of connectors electrically coupling the semiconductor chip to the antenna array.

Antenna array with replaceable antenna cell

An active phased array antenna system with hierarchical modularized architecture is introduced, which includes an array antenna and a beamforming circuit. The array antenna includes a plurality of antenna units, number of which is N and which are arranged in array form. The beamforming circuit is for receiving a plurality of input signals and a plurality of phase control signals, and includes a hierarchical circuit structure based on phase shifters, for outputting a plurality of output signals based on the input signals according to phase values corresponding to the phase control signals and combinations of the phase values; the output signals are respectively coupled to the antenna units so as to generate a radiation pattern, wherein number of the phase control signals is T, T&#x3c;N, wherein N=&#x3a0;N, M=&#x3a3;N, M&#x2212;P&#x2264;T&#x2264;M, N(i=1 to P), M, P are all positive integers, P&#x2265;2, N&#x2265;2.
