📢𝗙𝗲𝗮𝘁𝘂𝗿𝗲𝗱 𝗔𝗿𝘁𝗶𝗰𝗹𝗲 𝗔𝗹𝗲𝗿𝘁!📢 We are pleased to share with you the following featured work published on IEEE AWPL: Daosheng Huang, Feng Liang, Xiangru Wang, and Bing-Zhong Wang, “A Millimeter Wave Dual-Band Antenna Based on Microstrip Dual-Loop and Patch, ” 𝘐𝘌𝘌𝘌 𝘈𝘯𝘵𝘦𝘯𝘯𝘢𝘴 𝘢𝘯𝘥 𝘞𝘪𝘳𝘦𝘭𝘦𝘴𝘴 𝘗𝘳𝘰𝘱𝘢𝘨𝘢𝘵𝘪𝘰𝘯 𝘓𝘦𝘵𝘵𝘦𝘳𝘴, vol. 23, no. 10, 2024. 🔍 𝐊𝐞𝐲 𝐇𝐢𝐠𝐡𝐥𝐢𝐠𝐡𝐭𝐬: · The proposed antenna element realizes millimeter-wave dual-band operation at 27/38 GHz by a series combination of a microstrip patch antenna and a microstrip dual-loop antenna. The microstrip patch antenna operates as a radiation structure at high frequency band and a transmission structure at low frequency band, while the microstrip dual-loop antenna operates as a radiation structure at low frequency band and a transmission structure at high frequency band. · The series element structure leads to a high element gain of about 10 dBi in both frequency bands. The operating bandwidth in both frequency bands is obviously improved by the introduction of parasitic patches. Then a 2×1 array based on the proposed element and differential feed with low cross-polarization level is demonstrated. 𝘙𝘦𝘢𝘥 𝘵𝘩𝘦 𝘧𝘶𝘭𝘭 𝘱𝘢𝘱𝘦𝘳 𝘶𝘴𝘪𝘯𝘨 𝘵𝘩𝘦 𝘧𝘰𝘭𝘭𝘰𝘸𝘪𝘯𝘨 𝘭𝘪𝘯𝘬: https://lnkd.in/g-z3sAuY

My first IEEE Access paper is now published!!! ==> https://lnkd.in/ggcqhJ56 This paper presents a direct bi-characteristic-impedance transmission line (BCITL) extraction method from scattering parameters (S-parameters) for asymmetric reciprocal transmission line modeling. The BCITL model is a generalized transmission line model that the transmission line possesses different characteristic impedances depending on the direction of signal propagation. In this work, we also demonstrate the usefulness of the BCITL model in the analysis of "two-port" differential antennas. Our findings highlight promising physical insights obtained from this transmission-line-based analysis, which cannot be observed by S-parameters. I'd like to express my gratitude to Prof. Danai Torrungrueng, Prof. Panuwat Janpugdee, Prof. Supakit Kawdungta, and P'อ้วน Kitiphon Sukpreecha for providing me with an opportunity to work on this project, enhancing my skills, and helping me through my hard time.
