94 GHz substrate integrated waveguide fed antenna in LTCC technology

Abstract

This paper presents a novel 94 GHz parasitic antenna array with a substrate integrated waveguide feed. The antenna array was designed for a six tape low-temperature co-fired ceramic process, offering the opportunity of easy integration with other passive and active components. Simulations have shown a high directivity of 8.2 dBi at the central operating frequency of 94 GHz, with reflection losses lower than -10 dB for a 4.75 GHz bandwidth.
