摘要：
A compact dual-polarized magneto-electric (ME) dipole antenna is investigated in this letter. The antenna is formed by a monolithic cross-shaped dielectric block with a rectangle part for support and two pairs of orthogonal metal strips printed on the bottom of the cross dielectric. In the antenna design, the dielectric plays a role as a magnetic dipole (MD) while the metal strips are equivalent to an electric dipole (ED). For demonstration, a dual-polarized prototype antenna with the electrical size of 0.38 lambda(0) x 0.38 lambda(0) X 0.14 lambda(0) has an impedance bandwidth of 14.1% from 3.25 to 3.85 GHz with vertical bar S-11 vertical bar <-15 dB covering the N78 band for fifth-generation (5G) New Radio (NR). Furthermore, the antenna has a stable gain of 8.5 +/- 0.4 dBi across the operating frequency range, demonstrating the high stability of the radiation characteristic for the two radiation modes.
