[IEEE 2018 IEEE CPMT Symposium Japan (ICSJ) - Kyoto, Japan (2018.11.19-2018.11.21)] 2018 IEEE CPMT Symposium Japan (ICSJ) - A 77GHz Antenna-in-Package with Low-Cost Solution for mm Wave System Integration
摘要： This work provides Antenna in package (AiP) implemented on Advanced single sided substrates (aS3 package) , which utilizes low-cost substrate and low-cost assembly process. The dipole antenna implemented on aS3 package results in a peak gain of 5 dBi at operating frequency band. The return loss of < - 10 dB bandwidth is from 65 to 81 GHz. The resonant rectangular series-fed patch array implemented on aS3 package results in a peak gain of 8 dBi at operating frequency band. The return loss of < - 10 dB bandwidth is from 76 to 81 GHz. The antenna performance of antenna on aS3 package meets the requirements of 77 GHz automotive radar systems. This work also discuss with the impact of fabrication inaccuracies on the antenna bandwidth and gain. For 77 GHz automotive radar application, the corner analysis of process variation supports correct antenna performance and a short time to market.

[IEEE 2018 International Conference on Microwave and Millimeter Wave Technology (ICMMT) - Chengdu, China (2018.5.7-2018.5.11)] 2018 International Conference on Microwave and Millimeter Wave Technology (ICMMT) - A 120 GHz LTCC Packaged Horn Antenna with a Radome and Soft Surface Structure
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.
