An aperture coupled magneto-electric (ME) dipole for 5G Backhauling systems is proposed in this article. A substrate integrated waveguide (SIW) is used to feed the antenna. The electric dipole is formed by four identical patches, while the magnetic dipole is composed by four vertical metallic shorted vias. Moreover, a crossed strip is introduced to connect the four patches in the top metal layer to widen the impedance bandwidth and a cage of vias is added to suppress the generation of surface waves and to boost the radiating element gain. The simulated impedance bandwidth with $\vert S_{11}\vert$ < -10 dB for the proposed SIW-fed aperture coupled ME-dipole antenna fully covers the E-Band (71-86 GHz), with a fractional bandwidth of more than 20%. The simulated antenna peak gain is 10.8 dBi at 84 GHz and the 3-dB beamwidth is stable with a variation up to 1 dBi within the band of interest. The proposed E-band ME dipole antenna is very suitable for 5G backhauling systems, as it can be integrated into an array configuration for realizing beam-steering operations.

Abstract
An aperture coupled magneto-electric (ME) dipole for 5G Backhauling systems is proposed in this article. A substrate integrated waveguide (SIW) is used to feed the antenna. The electric dipole is formed by four identical patches, while the magnetic dipole is composed by four vertical metallic shorted vias. Moreover, a crossed strip is introduced to connect the four patches in the top metal layer to widen the impedance bandwidth and a cage of vias is added to suppress the generation of surface waves and to boost the radiating element gain. The simulated impedance bandwidth with $\vert S_{11}\vert$ < -10 dB for the proposed SIW-fed aperture coupled ME-dipole antenna fully covers the E-Band (71-86 GHz), with a fractional bandwidth of more than 20%. The simulated antenna peak gain is 10.8 dBi at 84 GHz and the 3-dB beamwidth is stable with a variation up to 1 dBi within the band of interest. The proposed E-band ME dipole antenna is very suitable for 5G backhauling systems, as it can be integrated into an array configuration for realizing beam-steering operations.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
