Magneto Electric (ME) dipoles have been widely studied over the last few years. They are becoming increasingly popular as they allow to generate a wide bandwidth in a printed circuit board (PCB). Nevertheless, their principle of operation requires the use of relatively thick substrates (i.e. about 0. 25λ0, where λ0 is the free-space wavelength) thus resulting in a bulky stack-up. This work tackles this problem by proposing a new type of low -profile ME dipole. The proposed configuration is fed using a slot-coupled microstrip line feed and it employs bandwidth enhancement solutions previously used in metal-only structures. As a result, an ultrathin antenna is achieved which operates over a 20% bandwidth at Ka-band while using an ultrathin dielectric layer being the antenna thickness equal to 0.082 λ0. Moreover, the antenna has a gain of about 5.5 dBi across the entire bandwidth, which makes the proposed design suitable for next generation 5G base stations.

Abstract

Magneto Electric (ME) dipoles have been widely studied over the last few years. They are becoming increasingly popular as they allow to generate a wide bandwidth in a printed circuit board (PCB). Nevertheless, their principle of operation requires the use of relatively thick substrates (i.e. about 0. 25λ0, where λ0 is the free-space wavelength) thus resulting in a bulky stack-up. This work tackles this problem by proposing a new type of low -profile ME dipole. The proposed configuration is fed using a slot-coupled microstrip line feed and it employs bandwidth enhancement solutions previously used in metal-only structures. As a result, an ultrathin antenna is achieved which operates over a 20% bandwidth at Ka-band while using an ultrathin dielectric layer being the antenna thickness equal to 0.082 λ0. Moreover, the antenna has a gain of about 5.5 dBi across the entire bandwidth, which makes the proposed design suitable for next generation 5G base stations.
