An aperture coupled substrate integrated waveguide (SIW) fed magneto-electric (ME) dipole for 5G Backhauling systems is proposed in this article. The electric dipole is formed by four identical patches, while the magnetic dipole is composed by four vertical metallic shorted vias. A crossed strip is introduced to connect the four patches in the top metal layer to widen the impedance bandwidth. Moreover, to suppress the generation of surface waves and to boost the radiating element gain, a cage of vias is added. To validate the proposed idea, an array 7×7 has been fabricated and the central element has been measured. An experimental assessment showed a maximum measured antenna gain of 8.4 dBi at 74 GHz, while the antenna maintains good performance from 74 to 81 GHz. The proposed E-band ME dipole antenna is very suitable for 5G backhauling systems, as it can be useful for realizing mechanical beam-steering operations, especially for beam-switching applications.

Moreover, to suppress the generation of surface waves and to boost the radiating element gain, a cage of vias is added. To validate the proposed idea, an array 7×7 has been fabricated and the central element has been measured.
