ABSTRACT:
An antenna having an antenna aperture area and an antenna reactance comprises a first antenna element (31) defining a first aperture area and a first reactance and a second antenna element (32) connected in parallel to the first antenna element to put a miniature radio receiver into operation in a desired frequency band. The second antenna element has a second aperture area and a second reactance greater than the first aperture area and reactance, respectively, so that the antenna aperture area and reactance are substantially determined by the second aperture area and the first reactance, respectively. The first and the second aperture areas may be coplanar. Alternatively, the aperture areas may be orthogonal to each other.
