This work presents a new breast tumor detection system based on an omnidirectional microstrip ultra wideband antenna. The localization coordinates of the tumor are studied in detail for better tumor detection. The coordinates of the corresponding max
This paper proposes a novel miniaturization technique to enhance the radiation properties of small multi-layer patch antenna used in packaged circuits. The multilayered antenna design is composed of three layers with different shapes. An enhancement
