Latest Patents
Mari Paunuma holds a patent for a multiband antenna, which is particularly useful in mobile stations. The invention features a PIFA-type antenna positioned within the covers of a mobile station. This antenna includes a slot radiator, and in the planar element, there is a second slot that creates two radiating conductive branches of different lengths when viewed from the feed point. Each of the three radiators operates on its own distinct band. The design also incorporates a whip element that can be adjusted in relation to the PIFA part. When extended, the whip element connects with the shorter branch of the planar element, enhancing the antenna's performance in the lowest operating band. The design compensates for the whip's influence on the uppermost operating band by including a third slot in the planar element. This innovative structure is relatively simple and economical to manufacture, allowing for effective three-band operation even without the whip element.
