Dual-Polarized Antenna Array Modularization by LTCC Process at Millimeter Wave Frequencies for 5G Applications

A broadband antenna array module is presented for 5G CPE applications, which was fabricated by low temperature co-fired ceramic (LTCC) for 5G base station or customer premise equipment (CPE) applications. The antenna elements are dual-polarized along +/-45 degrees to avoid the harmful multi-path effects from metal supporting structures. They are in a cross-dipole architecture with tapered shapes to improve bandwidth, which were designed on multi-layered dielectric substrates to produce a bandwidth larger than 4 GHz from the full-wave simulations with good isolation. ? 2021 Taiwan Microwave Association.
