Abstract :
The expanding use of wireless devices has prompted the need of larger bandwidths by these devices. This need is a result of larger bit-rates or the use of different standards using different frequency bands. In this work, the design and test of a wide band antenna and its matching circuit is presented The wide band antenna is of the Archimedes type because it has a compact size and can be easily manufactured using inexpensive PCB technology. The possibility of including the matching circuitry in the same PCB is also studied
