[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.

The Design of Dual Circularly Polarized Series-Fed Arrays
摘要： This paper presents the design of dual circularly polarized (CP) series-fed arrays based on Sequential rotation (SR) technique with uniform radiation elements. The radiation elements and feeding network used in the array are uniform, which leads to the possibility of dual-CP radiation by series-fed SR arrays. Meanwhile, the elements radiate unequal powers due to this arrangement. The relationship between the axial ratio (AR) and four key parameters of the array is derived and thoroughly discussed. Good polarization purity and port isolation can be realized by optimizing these parameters. A dual-CP array working at 10 GHz is designed with the help of the analysis. Experimental results show that the proposed antenna has good properties.

Single-Layer Series-Fed Planar Array with Controlled Aperture Distribution for Circularly Polarized Radiation
摘要： We propose a compact circularly polarized series-fed patch array with enhanced radiation performance at S-band. To our best knowledge, no similar single-layer structure has been designed, measured and reported in the literature with equivalent radiation performances in terms of reduced sidelobe-level (SLL) and aperture efficiency as well as compactness and simplicity. The planar array consists of a 50-? microstrip single feed point, offering uniform and efficient excitation of all its elements that enables a broadside beam with high-gain and low sidelobes. A feed network for such aperture control is designed and optimized to provide good impedance matching with a two-point excitation per radiating element, which is based on 0? and 90? meander lines to enable circularly polarized radiation. A structure made by a 4×1 arrangement of square patches is simulated, optimized, and manufactured, providing a realized gain of about 10 dBic and a SLL below ?15 dB. Very good axial ratios and high efficiencies are obtained. The proposed antenna may be of interest for next-generation far-field wireless power transmission systems and other applications including target tracking, radar and internet of things technologies requiring efficient circularly polarized radiation.

A high‐isolation dual‐polarized quad‐patch antenna fed by stacked substrate integrated waveguides for millimeter‐wave application
摘要： A high-isolation dual-polarized quad-patch antenna fed by stacked substrate integrated waveguide (SIW) that is suitable for millimeter-wave band is proposed in this paper. The antenna consists of a quad-patch radiator, a two-layer SIW feeding structure and two feeding ports for horizontal and vertical polarization. The two-layer stacked SIW feeding structure achieves the high isolation between the two feeding ports (|S21| ≤ ?45 dB). Based on the proposed element, a 1 × 4 antenna array with a simple series-fed network is also designed and investigated. A prototype working at the frequency band from 38 to 40 GHz is fabricated and tested. The results indicate that the proposed antenna has good radiation performance at 38 GHz that covers future 5G applications.

[Institution of Engineering and Technology 12th European Conference on Antennas and Propagation (EuCAP 2018) - London, UK (9-13 April 2018)] 12th European Conference on Antennas and Propagation (EuCAP 2018) - Novel Implementation for a Broadband Cavity-Backed Slot Fed in Transmission Configuration
摘要： A novel radiating element proposed previously by the authors is alternatively implemented using enclosed microstrip configuration. The radiating element shows broad impedance bandwidth and unidirectional radiation pattern. Its transmission configuration makes it ideal for series-fed arrays. The new implementation presents significant improvements concerning easiness of fabrication, robustness and compatibility with other technologies. A prototype designed to work in the 6 GHz band has been fabricated and measured, and has shown the expected performance: a 50% of fractional impedance bandwidth and unidirectional, stable radiation patterns.
