摘要： There is herein disclosed a miniature dual band antenna with wideband and dual band characteristics. The antenna of the present invention includes a first radiator having one end connected to a feed element, and a second radiator substantially parallel to the first radiator and spaced apart from the first radiator by a predetermined distance, the second radiator having one end grounded. The antenna resonates in a first resonant frequency, a second resonant frequency and a third resonant frequency that is a multiple frequency of the first resonant frequency. Accordingly, a wideband characteristic can be obtained by bringing the first resonant frequency and the second resonant frequency close to each other and a wideband characteristic can be obtained by the third resonant frequency. The antenna of the present invention can be applied to signal transmission and reception of the UHF band and the L-band.

摘要： A single-layer dual-band antenna with circular polarization is disclosed. The antenna includes a first radiator formed on the top surface of a substrate and electrically coupled to a feeding element, and a second radiator formed on the top surface of the substrate, spaced apart from the first radiator by a predetermined distance and electromagnetically coupled with the first radiator. The antenna is thin because it has a single-layer structure. Furthermore, there is no deterioration in the radiation characteristic due to interference between the radiators. Moreover, impedances of the radiators can be independently matched at their frequency bands by adjusting the position of a feed point and the relative position of the radiators.

摘要： There is herein disclosed a miniature antenna with an adjustable resonant frequency without any change of the radiation performance, and an apparatus including the same. The antenna comprises two radiation conductors connected to a feed section and a ground plane, respectively, and a resonant circuit section as a zero-order resonator including inductors, transmission lines and a capacitor. The inductors and/or capacitor are configured of a variable element so that the impedance of the variable element can be controlled to adjust the resonant frequency of the antenna. In addition, the installation position and the size of the ground plane within the apparatus with respect to the transmission lines can also be controlled to adjust the resonant frequency of the antenna. Alternatively, the antenna may further comprise a variable capacitor connected to the inductors so as to adjust the effective inductance and change the resonant frequency. The radiation lines of the antenna are not related with determination of the resonant frequency, and thus the radiation performance is not affected by the adjustment of the resonant frequency.
