    • 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.
    • 具有天线孔径区域和天线电抗的天线包括限定第一开口区域和第一电抗的第一天线元件(31)和与第一天线元件并联连接的第二天线元件(32),以将微型无线电接收器 在期望的频带中进行操作。 第二天线元件分别具有大于第一开口面积和电抗的第二开口面积和第二电抗,使得天线孔径面积和电抗分别基本上由第二开口面积和第一电抗决定。 第一和第二开口区域可以是共面的。 或者,孔径区域可以彼此正交。
