    摘要: Antenna systems employing multiple linear polarization antennas that have capacitively loaded magnetic dipoles and that are magnetically coupled to generate a circular polarization. In a first embodiment of the present invention, two intersecting linearly polarized antennas elements are arranged to obtain a circular polarization. In a second embodiment, a first linearly polarization antenna is placed orthogonally to a second linearly polarization antenna where a single active feed excites the first linearly polarization antenna.

    摘要: Various resonant modes of a multiresonant antenna structure share at least portions of the structure volume. The basic antenna element has a ground plane and a pair of spaced-apart conductors electrically connected to the ground plane. Additional elements are coupled to the basic element, such as by stacking, nesting or juxtaposition in an array. In this way, individual antenna structures share common elements and volumes, thereby increasing the ratio of relative bandwidth to volume.

    摘要: The invention discloses a patch antenna structure in which a full transmission line is replaced by a set of transmission lines connected between two slots or radiative elements. Components can be inserted in the space between the transmission lines. In a second embodiment, the transmission lines are cranked or bended for a more compact dimension of transmission lines. The cranked or bended transmission lines can also be loaded by inductive elements. In a third embodiment, a patch antenna is constructed with n sets of transmission lines between the two slots, where each set of transmission line produces a different electrical length in accordance with a particular frequency. In a fourth embodiment, a set of intermediate filters is added within the transmission lines for differentiating the frequencies.
