A 2.5 mW D‐Band Broadband Simultaneous Noise‐ and Input‐Matched InP LNA
Electronics Letters, Volume 62, Issue 1, January/December 2026.This work presents a D‐band, ultra‐low‐power, broadband two‐stage low‐noise amplifier (LNA) implemented in a 250‐nm InP DHBT process. Using a simultaneous noise and input matching technique with a gain‐boosted feedback network, the LNA achieves 6.2 dB noise figure and 27 dB gain from 130 to 155 GHz while consuming only 2.5 mW.

GPR Antenna Modelling Based on DML Exploiting Cosine Similarity Metric
IET Microwaves, Antennas &Propagation, Volume 20, Issue 1, January/December 2026.The proposed SNN‐KNN‐GPR framework. ABSTRACT Traditional full‐wave electromagnetic simulation software, such as HFSS or CST, requires substantial computational resources and time consumption, as does the construction of surrogate models when acquiring new samples. To overcome this data efficiency challenge, we propose a Data Augmentation (DA) modelling
