Microwave and Optical Technology Letters, Volume 67, Issue 9, September 2025.ABSTRACT This paper presents a switched beam patch antenna array fed by a 4 × 4 Butler Matrix (BM) working at 100 GHz for the first time, based on a novel metallic‐nanowire‐filled membrane technology (MnM). Butler matrix (BM) is well‐known as a simple passive beam‐forming network with low loss to realize switched beam.

Advanced Engineering Materials, Volume 27, Issue 15, August 2025.This study explores aerosol jet‐printed (AJP) surface roughness, its effects on the performance of microwave electronics, and its process contributors. First, an electromagnetic model is vetted for AJP's unique roughness signature. Simulations are built which show process‐induced roughness is as significant as conductor resistivity in driving microwave
