“…Magnetoelectric dipole antenna fed with SIW to coaxial transition (SCT) exhibits wide‐band in Gao et al 16 Consequently, the complexity of these systems is increased to improve BW. The reflection slope synthesis method is also applied to rectangular slots to improve the BW 17 . The literature extensively covers SIW slot antennas with diverse structures, such as multiple resonant modes, hybrid configurations and complex multilayer designs to achieve wide BW.…”

SummaryThis article analyses a substrate integrated waveguide (SIW) fractal koch surface (FKS) slot antenna performance for Ka‐band applications. This FKS slot shape is obtained by modifying the conventional rectangular slot with the first iteration of the FKS method. The resultant FKS slot behaves as a radiator in the provided space. A single‐ and two‐element FKS slotted SIW antenna characteristics are analysed on a 20 mil thick RT/Duroid 5880 substrate and compared with the conventional rectangular slot. The proposed antenna with dimensions mm3 achieves an impedance bandwidth from 27.4 to 32.1 GHz with a fractional bandwidth of 15.79% and achieves a gain of 8.3 dBi in broadside direction by improving space filling factor in SIW structure. The prototype of the SIW‐fed FKS slotted antenna array measurement results is satisfactory with the simulation results.

This letter reports a 28-GHz multi-port magneto-electric (ME) dipole array for 5G applications. The proposed antenna array enlarges the system polarization diversity with the capability of being utilized as a balanced antenna, a dual-polarized antenna and a circularly polarized antenna. Co-planar waveguide (CPW) lines are used to connect ME dipole radiators to achieve a high gain with simple feeding structure. The proposed antenna array exhibits a -10dB impedance bandwidth of 12.8% and a maximal peak realized gain of 13.52 dBi as a balanced antenna, and exhibits a -10dB impedance bandwidth of 28.57%, a 3-dB axial ratio bandwidth of 16% and a maximal peak realized gain of 12.15 dBi as a circularly polarized antenna.

“…The design was further replicated into 1 × 8 planar phased arrays. Herrero‐Sebastián et al 13 designed a wide‐band antenna using a slot inside a SIW cavity which worked for a millimeter‐wave 5G band. The author used a new synthesis method to optimize the position and distribution of the slots along SIW for wideband coverage.…”

This letter provides a detailed explanation of a novel high‐gain cross slot substrate integrated waveguide (SIW) rectangular cavity‐backed antenna. The main SIW cavity is further divided into seven small linearly placed cavities at a distance of 0.9λg ${{\rm{\lambda }}}_{{\rm{g}}}$. Each cavity contains a cross‐slot at an equal distance from each other. The defective ground structure is placed at the bottom layer of an antenna with two metallic vias to divert the wave towards edge slots for further gain improvement. The antenna shows a measured gain of approximately 12 dBi from 11.37 to 11.78 GHz. The radiation efficiency of 92% and the front‐to‐back ratio of 28 dB is achieved. The proposed antenna provides a very high directive fan‐like pattern which can be utilized for satellite and radar applications in the X‐band.
