Write what each word means, using the article.

Do not copy the article. Write two things you learned, the way you would explain them to a friend.

Answers below are taken from the article’s stored facts, so they match what the student read.

1. How big is Fractal antenna?Ubiquitous in mobile communication devices, wireless networking, and advanced signal processing systems
2. What is the mathematical basis?Derived from fractal geometry, characterized by self-similarity and iterative construction
3. What is the electromagnetic property?Exhibits multiple resonant frequencies, enabling multiband or wideband operation
4. Why do fractal antennas use self-similarity?Self‑similarity makes the antenna have many little parts that can each resonate with a different frequency. This lets the antenna listen to many signals without needing extra tuning parts.
5. How does a fractal antenna help smartphones?In a smartphone, a fractal antenna can switch between cellular, Wi‑Fi, Bluetooth, and GPS signals all in the same tiny spot. That means the phone stays small but still talks to all the networks it needs.

Fractal Geometry: A branch of mathematics studying complex shapes with self-similar patterns at all scales.
Self-Similarity: The property of an object or pattern where parts are geometrically similar to the whole.
Multiband Antenna: An antenna designed to operate effectively at two or more distinct frequency bands.
Wideband Antenna: An antenna designed to operate effectively over a continuous, broad range of frequencies.
