    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.
