Receiving Performance of Antenna-Coupled Electrode Electro-Optic Modulators for 5G Frequency Band

We have already proposed and developed an antenna-coupled-electrode electro-optic (EO) modulator for 28 GHz-band 5
^th
generation mobile communication as a receiving antenna. The designed EO modulator was fabricated a metal ground plane backed linear dipole array using a 50-μm-thick LiNbO
₃
crystal and a 250-μm-thick SiO
₂
base. In this paper, we have shown antenna receiving patterns for 1-element dipole antenna., 4-element dipole array antenna and 8-elemen dipole array antenna. Half power beam width for H-plane of our developed receiving antennas are 70, 25 and 11 degree for 1 element, 4-element and 8-element dipole array, respectively.
