Planar antenna array on LTCC and rogers substrates for 5G applications

Abstract

The next generation of wireless communications is the horizon, and the telecoms world is waiting to see exactly at which frequencies 5G will be implemented. Despite some unknowns and technological challenges, it is increasingly becoming clear that the millimeter-wave will be a key enabler for 5G by allocating more bandwidth to deliver faster, higher-quality video, and multimedia content and services. The principal advantage of use of millimeter wave bands is a large amounts of contiguous spectrum can be used, which allows the delivery of high data rates, but the technology is not so mature as in microwave frequencies. This paper presents array antennas using different materials: low-temperature cofired ceramics (LTCC) and Rogers substrates of a single radiating element, 1x1 and 2x2 array. The 2x2 element array antenna achieves a -10 dB bandwidth from 58 to 62 GHz with a peak gain of 12.2 dBi at 60 GHz.
