In this paper, a broadband dual-polarization rectangular dielectric resonator antenna structure is proposed with a “special matching section” added to the feeding microstrip line. Since the impedance becomes discontinuous after feeding the microstrip line to the bottom of the dielectric resonator antenna, it is necessary to increase the matching section. However, the matching section has a coupling effect at low frequencies, thereby exciting the low-frequency resonance point and realizing the characteristics of a wide frequency band. In addition, the feed structure is combined with a cross-shaped dielectric resonator antenna by means of differential feeding, and the proposed antenna achieves a better dual-polarization effect. The -10 dB bandwidth is 23.2 GHz-31.5 GHz, with a relative bandwidth of 30%, achieving a cross-polarization ratio of 40 dB.
