## 1 Introduction
In [14], another highly directional beam antenna design is recommended. On the other hand, it appeared heavy in bodyweight due to its different parasitic substrate on top of the innovation. However, an additional technique is exercised in [15], which still utilized a slotted ground of rectangular shape because its complication in production is not a suitable fit. In [16], a multiband high-gain antenna is suggested; however, having minimal bandwidth makes it inappropriate. In [17], to achieve a high gain, a microstrip Yagi antenna is offered, still with Periodic Bandgap (PBG), because its complication in structure design makes it unsuitable. Similarly, a Resonant Cavity Antenna (RCA) intended for the high-gain dual band is proposed in [18], in which stepped rings are added to improve gain and bandwidth. The additional enhancement in progress is certainly accomplished by using a Partially Reflective Surface (PRS), owning to the high permittivity substrate and circular patch etched on it. An innovative approach regarding feeding the dielectric resonator working with a metallic round patch antenna intended for mmW frequency band is suggested in [19]. Poreclaim material based upon a rectangle-shaped Dielectric Resonator Antenna (DRA) is placed over the substrate with relatively low permittivity and fed by a metallic circular patch. The development investigation and analysis are carried out using a cross-slot aperture and rectangular slot. By implementing a cross-slot gap on the ground plane, a substantial improvement in gain along with bandwidth has been accomplished. The singly fed dielectric DRA recommended in this article offers high growth, efficiency, and wide bandwidth. A planar antenna with a high-gain-having conical beam intended for drone applications of mmW is radiated by utilizing some simple monopole [20] exclusively. Moreover, the operation and overall performance of the suggested design have been explored on top of a metallic, electrically significant plate. Among the particular side reflections and source radiation having the in-phase state, the suggested structure presented decent Conical Beam Radiation (CBR) efficiency. However, additionally attained increased peak gain and high radiation efficiency are in contrast with various other described designs on Conical Beam (CB) planar antennas having uncomplicated structure. The suggested planar antenna with high-gain-having CB is investigated along with various other described designs in expressing the beam-pointing angles, impedance BWs, radiation efficiencies, peak gains, dimensions, and planar/nonplanar geometries. In contrast with various other designs on CB planar antennas, the suggested model accomplishes the maximum gain and maximum radiation efficiency, having a relatively decent 10 dB impedance bandwidth. The proposed model in [21] comprises about three distinct models of array antennas primarily based on microstrip. To obtain resonance frequencies associated with the THz band, we applied corporate-series-fed approaches completely modeled using a CST MWS solver. The Substrate-Integrated Waveguide (SIW) is used for two proposed models. In contrast, Frequency-Selective Surfaces (FSSs) are utilized by the third proposed model that is undoubtedly intended to increase the actual antenna gain even more. [PERSON] et al. in [22] proposed a planar antenna with high gain having two ports intended for satellite band and future 5 th Generation mmW. In addition to operating in the mmW spectrum, the suggested model comes with an additional characteristic to operate for that satellite X-band at the same time. The proposed model achieves a considerable and significant gain by taking advantage of an inverse microstrip Yagi director geometry. The maximum gain from the model accomplishes the maximum value to obtain E-plane with much better directivity. The structure possesses a simple planar geometry with an imperfect ground for the satellite X-band, seen giving polarization diversity for being utilized to obtain the WGS satellite system.
