Dual-mode dual-band microstrip filters

2009 European Microwave Conference (EuMC), 2009
A compact dual-band microstrip bandpass filter is proposed using dual-mode resonators. Two microstrip loop resonators, one within the other, are employed to obtain dual-mode dual-band filter responses. Each loop resonator uses two loading elements to excite dual modes.

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
