In this paper, a novel 8×8 scale dual-band dual-polarized antenna array operating within Ku-band frequency range is proposed. A capacitive-coupled probe-fed antenna is presented to realize dual-band dual-polarization with wide bandwidth. To validate the concept, an 8×8 antenna array is designed and fabricated through multilayer PCB process. The measured bandwidths for the V-polarized and H-polarized ports are 10.17 GHz~13.48 GHz (28%) and 12.65 GHz~14.9 GHz (16.3%) respectively. Significantly, the isolation between the two ports consistently exceeds 20 dB across both frequency bands. The measured gains could reach 19.33 dBi @12.5 GHz for the V-polarization and 20.11dBi @14.5 GHz for the H-polarization, and exhibiting cross polarization levels lower than -25 dB.
