60-GHz multi-layer parasitic microstrip array antenna with stacked rings using multi-layer LTCC substrate

This paper proposes a novel high-gain millimeter-wave microstrip array antenna formed on a multi-layer low temperature co-fired ceramic (LTCC) substrate. The proposed antenna employs a multi-layer parasitic microstrip array antenna with stacked rings. This paper describes the design and characteristics of the proposed antenna. The antenna performance is also calculated by electro-magnetic simulation. The thickness of the proposed antenna is 0.5 mm and the proposed antenna achieves the antenna gain of 12.9 dBi in calculation in a 60-GHz band. The proposed millimeter-wave antenna promises compact antenna-integrated RF modules that provide a low-cost millimeter-wave system-on-package.
