Abstract

This paper shows that it is possible to make functional probe-fed patch antennas on low-temperature co-fired ceramic (LTCC) substrates for 60 GHz. The designed antennas were realised on a 0.5-mm-thick LTCC substrate using a commercial Ferro A6-S LTCC material system. According to the measurements, a stacked square two-element patch antenna had 2.7 GHz and a circular single-element patch antenna had up to 6 GHz of the -10-dB-return-loss bandwidth. The manufacturing tolerances caused some de-tuning of the resonance frequency, plusmn1 GHz. The measured maximum radiation gain of the circular antenna was 5.9 dBi at 57 GHz
