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.

Abstract: A compact wideband single feed circularly polarized antenna is provided. The circularly polarized antenna may include a ground plane. The circularly polarized antenna may include a radiating patch with an embedded ring-shaped slot. The circularly polarized antenna may include a via that shorts a round section of the radiating patch surrounded by the ring-shaped slot to the ground plane. The circularly polarized antenna may include a coaxial feed. The inner conductive material of the coaxial feed may be connected to the radiating patch and the outer conductive material of the coaxial feed may touch the ground plane. The circularly polarized antenna may include a slit-slotted parasitic square patch.
