An inverted U-shaped patch antenna for compact operation
Kin-Lu Wong,Hao-Chun Tung +1 more
TL;DR: In this paper, the inverted U-shaped radiating patch is formed by adding two downward rims at the two radiating edges of a planar rectangular or square patch, which effectively lowers the antenna's resonant frequency and results in large antenna size reduction (>50%.
