Abstract:
The wideband L-loop antenna is presented in this invention. It has excellent performance for lower band of UWB system and has the attractive features of small size, inexpensive, and easy to design. The antenna composed of a single metallic layer is printed on the top of a substrate and a coupled tapered transmission line is printed on the top of the same substrate. A L shape portion is formed by widening partially or wholly the width of a part of antenna elements in comparison with the other part.
