This research introduced a novel high‐gain low‐profile 4 × 4 microstrip patch array antenna with dual circular polarisation (CP) capabilities. The key innovation lies in the integration of two compact and symmetrical 1‐to‐4 microstrip power divider networks, enabling the antenna to operate in either left‐hand circular polarisation (LHCP) or right‐hand ...

GPR Antenna Modelling Based on DML Exploiting Cosine Similarity Metric
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

Uniform Circular Array Antenna for Dual‐Mode Orbital Angular Momentum Generation at 6 GHz
Orbital angular momentum (OAM) antennas have recently attracted attention for their potential to enhance communication capacity and and robustness against interference. However, most existing designs rely on complex multilayer feed structures. This work presents a compact, single‐layer, series‐fed dual‐mode OAM antenna composed of four patches arranged
