Abstract: A phased array antenna that maximizes antenna gain and minimizes or avoids grating/side lobes issues. The phased array antenna includes a receiver antenna array including one or more groups of receiver radiating elements, where each group of receiver radiating elements includes a first receiver subarray of receiver radiating elements and a second receiver subarray of receiver radiating elements. The phased array antenna further includes receiver core chips, including, for each of the one or more groups of receiver radiating elements, a first receiver core chip associated with the first receiver subarray and a second receiver core chip associated with the second receiver subarray. Additionally, the phased array antenna includes receiver feeding networks, including, for each of the one or more groups of receiver radiating elements, a first receiver feeding network including first feed lines and a second receiver feeding network including second feed lines.
