The gain enhanced antipodal Vivaldi antenna (AVA) is implemented in this study for fifth-generation (5G)communication applications. At first, the conventional AVA is designed and then metamaterial and rectangular corrugations are added to AVA to enhance its gain from 7.75 to 9.53 dB. The designed antenna size is 40 mm × 24 mm × 1.6 mm and it is fabricated on the FR4 substrate. Further, modified AVA with metamaterial and corrugation increases higher cut-off frequency from 30.62 to 34.52 GHz. The gain of the designed antenna varies between 5 and 9.53 dB over 24.77 to 34.52 GHz and its bandwidth is 9.75 GHz. The designed antenna covers 25 to 29.5 GHz and 31.8 to 33.4 GHz 5G frequency bands. Experimental results and the simulated results are nearly same, which demonstrate that the designed antenna can be used for 5G communication applications. K E Y W O R D S 5G communication, antipodal Vivaldi antenna (AVA), corrugations, enhanced gain, metamaterial Amruta S. Dixit and Sumit Kumar contributed equally to this work.

“…Out of these shapes, windmill shape is a suitable shape that provides compact, improved return loss and wideband AVA. Figure 7(a) shows a typical fabricated AVA antenna of windmill shape and its simulated return loss is demonstrated in figure 7(b) which indicates that windmill flare shape outputs compact and wideband antenna [20].…”

“…The leaf structure of AVA is employed to alleviate the cross-polarization of AVA [35], [50]. Although due to this leaf structure the design of an antenna becomes complex as shown in figure 6(d), the design can be made simple and compact by using bow tie [16] and windmill [20] as shown in figure 6(e) and 6(f). But, both bow tie and windmill shapes reduce the AVA gain.…”

The increasing proliferation of advanced devices for UWB, 5G communication, micrometerwave, and millimeter-wave communication demands an antenna which can handle huge data rates, provides high gain and stable radiation pattern as a panacea of most of the current wireless communication problems. Many different antenna designs have been proposed by the researchers but, Antipodal Vivaldi Antenna (AVA) has drawn the attention of most of the researchers because of its high gain, wide bandwidth, less radiation loss, and stable radiation pattern. Different methods are presented to make AVA more compact while maintaining the performance of an antenna to an acceptable level. These different methods are substrate choice, flare shape, slots, and feeding connectors. Also, AVA performance can be enhanced by incorporating corrugation, dielectric lens, patch in between two flares of AVA, balanced AVA (BAVA), metamaterial, computational intelligence (CI), and AVA array. The AVA performance enhancement techniques modify the electrical and physical properties of an antenna which in turn improves its performance. A large number of performance enhancement methods of AVA design have been proposed, however, no comprehensive study exists to categorize these performance enhancement techniques and outline their concepts, advantages, disadvantages, and applications. So, in this paper, we have attempted to outline all methods available for enhancing and optimizing the parameters of AVA. Additionally, to validate some of the important performance enhancement methods, they are incorporated in the basic conventional AVA design and further simulation results are obtained for the same which are in line with the surveyed literature. Each method is explained in detail by incorporating its key points, merits, and demerits. Moreover, illustrations from the literature are given to demonstrate improvement in the parameters as a result of applying a particular performance enhancement technique. INDEX TERMS Antipodal Vivaldi antenna (AVA), AVA array, balanced antipodal Vivaldi antenna (BAVA), corrugations, dielectric lens, metamaterial, parasitic patch, slots.

A half‐split inverted‐frustum shaped two‐port multi‐input–multi‐output (MIMO) dielectric resonator antenna is proposed with the ultra‐wideband response. The antenna provides the impedance bandwidth of 132.69% (7−34.6thinmathspaceGHz) with each port. The MIMO performance parameters like envelope correlation coefficient, diversity gain, mean effective gain and channel capacity loss remain in the acceptable limits with the isolation more than 20 dB throughout the operating band. In addition, the antenna provides the peak gain ranging from 4−9.5thinmathspacedBi at port‐1 and 4−8thinmathspacedBi at port‐2.
