| description | A compact and wideband differentially fed dual-polarized antenna with high common-mode suppression is investigated in this paper. A square patch with crossed-slot consisting of four slant funnel-shaped slots is used as the radiator, generating slant ±45° linear polarizations. Two orthogonal placed baluns, each connected with two open-end stubs, act as the feeding network. Under differential-mode (DM) excitation, the resonating mode of the square patch and quarter-wavelength mode of the funnel-shaped slots can be excited at low and high frequency band, respectively, which enhances the operation bandwidth of the designed antenna. By using differential excitation, a high level of common-mode (CM) suppression can be realized. To verify the design, the prototype of the designed antenna and an antenna array consisting of four elements are fabricated and measured. The experimental results indicate that a DM reflection coefficient better than -15 dB and a CM suppression level better than 1 dB are achieved within a wide impedance bandwidth of 55.3% (1.66 to 2.93 GHz). A high isolation and a stable radiation pattern can be observed within the operating band. Besides, the proposed antenna maintains a small aperture size of 0.36λ<sub>0</sub> × 0.36λ<sub>0</sub>, where λ<sub>0</sub> is the free-space wavelength at the center frequency of operation band. |
