“…Thus it is required to apply different methods of mutual coupling reduction methods. Corrugation and triangular metal directors are used with AVA array in [19], [44] to achieve high and constant gain, low sidelobes and reduction in beam squint. Balanced Antipodal Vivaldi Antenna (BAVA) array not only gives wide bandwidth but also enhances other parameters of BAVA [83].…”

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.

The deviation between the two oscillators in BiSAR systems will cause a residual modulation of echo signal. Therefore, the phase synchronization is an important issue that must be addressed for BiSAR systems. An advanced non-interrupted phase synchronization scheme is used for the LuTan-1 SAR satellite. The synchronization transceiver (STR) is designed for transmitting and receiving synchronization signals. In addition, STR mainly consists of master and auxiliary transceivers and switch module. Furthermore, the function and working principle of STR are introduced, and the detailed design of each part is described. The measured results are also evaluated to prove the performance of the STR. In addition, the phase synchronization accuracy is also demonstrated to verify the effectiveness of the non-interrupted synchronization scheme. The standard deviation (STD) of the residual phase is less than 0.3 degrees. The results have guiding significance for the synchronization unit design of LuTan-1 and the future BiSAR system.

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.
