A packaged microstrip line feed network on a single substrate surface is presented in the Ka-band for a 4 × 4 dual-polarized array with a capability to be expanded to higher order 2N × 2M, where N and M are integer numbers larger than 1. A dual-polarized aperture-coupled magneto-electric dipole antenna is designed as a single element with 20% bandwidth of −10 dB reflection coefficients, ports’ isolation better than 35 dB, cross polarization less than −25 dB within the main beam view-range of 30°, and gain of 8 dBi. A 4 × 4 array is implemented that maintains a bandwidth of 16.7% at 30 GHz with a maximum gain of 19.3 dBi.
