摘要： There is a strong interest to implement antenna-in-package (AiP) systems for a variety of applications such as imaging, beamforming, integrated transceivers, and radars. Substrate integrated horn antennas are valuable AiP candidates due to their small form factor, ease of integration, and high gain. Alternatively, a volumetric packaging approach can significantly reduce the antenna’s form factor and enhance the gain. For the first time, in this paper, we present a 94 GHz low temperature cofired ceramic (LTCC) integrated volumetric pyramidal horn antenna. Using a vertical LTCC approach, a GCPW-fed single horn antenna was designed. Results show that the antenna operates from 91.6 GHz to 95.6 GHz for S11 <10 dB, with a realized gain of 8.7 dBi.

[IEEE 2018 48th European Microwave Conference (EuMC) - Madrid, Spain (2018.9.23-2018.9.27)] 2018 48th European Microwave Conference (EuMC) - Liquid Crystal Based SPDT with Adjustable Power Splitting Ratio in LTCC Technology
摘要： This paper presents design and characterisation of a new liquid crystal (LC) based single-pole double-throw (SPDT) with continuously adjustable power splitting ratio in low temperature co-fired ceramic (LTCC) technology. It is designed for a centre frequency of 30 GHz, the fully embedded LC phase including a key component, shifter in stripline topology. The SPDT shows a good matching with |S11| = ?10 dB over a bandwidth of 18 %. It exhibits an insertion loss of 9 dB to 11 dB and an isolation between 22 dB to 32 dB. The continuous tuneability not only allows the selection of each preferred power splitting ratio at the output ports, but also a tuning of the centre frequency. The high insertion loss arises from a certain surface roughness as well as a decreased conductivity of the gold metallisation used.

摘要： A 120 GHz step-profiled horn antenna integrated in low-temperature co-fired ceramic (LTCC) packages with a radome is presented in this paper. As an antenna-in-package (AiP) design, the proposed hollow horn structure is constructed by the cavities with several surrounding fences of vertical metallic vias in multilayer LTCC substrates. In consideration of the practical application, co-design with a thick cylindrical radome attached to the surface of the antenna is also studied. A planar soft surface structure in electromagnetics around the horn antenna is introduced so as to suppress the propagation of surface waves inside the radome and thus improve the gain performance. The simulated results indicate that more than 9 GHz bandwidth of -10 dB return loss and a gain of 12.56 dBi in the radiation direction at 0θ= ? are obtained.
