Abstract
In a U-shaped deformed folded dipole antenna, a first parallel section having a feeding point includes first and second L-shape sections, and a second parallel section without a feeding point includes first and second opposing side portions and a connecting side portion coupling ends of the first and second opposing side portions. Portions of the first and second L-shape sections arranged in parallel with the first and second opposing side portions have a width W1. Portions of the first and second L-shape sections arranged in parallel with the connecting side portion have a width W2. The first and second opposing side portions have a width W3. The connecting side portion has a width W4. An impedance of the deformed folded dipole antenna is controlled by setting the width W2 to be larger than the widths W1, W3, and W4.
