Abstract
A slotted monopole wideband antenna, comprising an insulating rectangular chip mounted on a carrier substrate, said carrier substrate including a feeding structure, and said chip comprising a first side adjacent to said feeding structure, a feed point of the antenna is located near said first side. An electrically conducting lamina is folded over four faces of said insulating chip, said lamina being connected to the feed point at one end, and to ground at another end. At least two slots are formed in an upper section of said folded lamina, said slots having the effect of lowering the principal resonance of said antenna, thereby providing a miniaturized antenna suitable for integration in a mobile wireless communications handset.
