ABSTRACT:
A radiating antenna element intended for small-sized radio devices and a method for manufacturing the same. The element (300) is manufactured of a plate comprising a dielectric substrate coated with conductive material on one side. The radiating conductor branches corresponding to the operating bands of the antenna are formed on the plate by removing the conductive coating by laser narrowly from the border line of the area (330) between the designed conductor branches. The conductor area confined by the created border groove can be used as a parasitic additional radiator. If needed, the conductor area confined by the border groove (331) can also be split into a number of small conductor areas (CA1, CA2), in order to make sure that the conductor area does not radiate or have any substantial effect on the coupling between the radiating conductor branches. A relatively wide area “invisible” on the operating frequencies of the radiating branches of the antenna can be formed between the branches by the customary laser technique. This means lower manufacturing costs compared to the use of the etching process, and the creation of problem waste is also avoided.
