Description

A designed microstrip grid array antenna at 94 GHz in a low-temperature co-fired ceramic (LTCC) technology was fabricated and measured. The designed and measured results are in good agreement. They show a 10-dB impedance bandwidth of 5.12 GHz from 90 GHz to 95.12 GHz (or 5.45% at 94 GHz), a maximal peak realized of 17.1 dBi with a 3-dB gain bandwidth of 5.5 GHz from 92.0 GHz to 97.5 GHz (or 5.85% at 94 GHz). These good performances make the microstrip grid array antenna a suitable candidate for 94-GHz applications.
