1. An antenna for operation in a plurality of predetermined frequency bands, comprising:
- at least one first part which encloses an area; and
at least one second part which does not enclose an area;
wherein the at least one first part and the at least one second part are coupled together in series with one another, and wherein the at least one first part and the at least one second part are so configured and arranged that the antenna has at least first and second resonant frequencies within the plurality of predetermined frequency bands, the at least one first part substantially defining the first resonant frequency and the at least one second part substantially defining the second resonant frequency.

Abstract
An antenna which can be operated in a number of frequency bands and has at least one part which encloses an area and at least one part which does not enclose an area, with the at least two parts including a single conductor part being connected in series with one another, and the at least two parts interacting with one another in such a manner that the antenna has at least two resonant frequencies in a definable position, and with each at the same time having a wide bandwidth.

28. A method of making an antenna, comprising the steps of:
-
providing a first antenna element having a three-dimensional shape in series with a second antenna element which does not have a three-dimensional shape; and
constructing the first and second antenna elements such that the antenna has at least first and second different predetermined resonant frequencies in which the first antenna element substantially defines the first resonant frequency and the second antenna element substantially defines the second resonant frequency. - View Dependent Claims (29, 30, 31, 32, 33)

34. A method of operating an antenna, comprising the steps of:
-
a) providing first and second antenna elements connected together in series;
b) allowing the first and second antenna elements to cooperatively resonant within a first frequency band substantially defined by the first antenna element; and
c) allowing the first and second antenna elements to cooperatively resonant within a second frequency band substantially defined by the second antenna element and different from the first frequency band. - View Dependent Claims (35, 36, 37, 38)
