“…Usually, the array antennas with multi-layered structures are used to achieve broadband and high-gain simultaneously, 29,30 which also reduces the size of the structure. The power distribution network described in Section 3.1 can be easily used as a feeding network to provide uniform excitation to the four subarrays.…”

A new class of multi-layer microstrip patch antenna (MPA) array fed by substrate integrated waveguide (SIW) cavities is presented for Ku-band applications. An efficient compact multi-layer SIW feeding network is designed, which has lower losses than the conventional corporate feeding network based on microstrip lines or coplanar waveguides. A 4 Â 4 array consists of four stacked layers, including three based on the SIW technology as a feeding network and one layer for the radiating antenna array. Each layer can easily be fabricated from a dielectric substrate and processed using the printed circuit board (PCB) technology.Afterward, all the PCB laminates are stacked together and tied by screws. The measured antenna operates from 11.2 to 13.6 GHz achieving 19.35% bandwidth. The measured peak gain at 12.5 GHz is 17.1 dBi, equivalent to 71.47% aperture efficiency. The fabricated array exhibits several advantages: broadband, low cost, compactness, high radiation efficiency, high aperture efficiency, and lightweight, which makes it a candidate for Ku-band satellite applications.

“…Therefore, the final design chosen was for an array of 4 × 10 SRRs. Finally, if the space between the SRR layers (d) is increased, there is a corresponding increase in the antenna gain at the upper frequency band (30-37 GHz) and better impedance matching in the lower frequency band (25)(26)(27)(28)(29)(30). For instance, if d = 0.06λ, the resulting peak gain is 12.7 dBi at 36 GHz.…”

In this paper, a magneto-electric (ME) dipole antenna excited by two slots through a printed ridge gap waveguide (PRGW) is presented. This antenna, which operates in the Ka-band, is considered as a dual complementary source (DCS), and exhibits a higher gain and a wider impedance bandwidth, compared to conventional ME dipoles. The proposed antenna has an impedance matching bandwidth with |S 11 | < −10 dB from 24.5 to 40 GHz with a stable gain of 10±1 dBi over the 25-35 GHz band. Moreover, by integrating horizontally three layers, each with an array of 4 × 10 split-ring resonator (SRR) unit cells on top of the DCS-ME dipole antenna, the realized gain is increased while maintaining the impedance bandwidth of the antenna. The antenna was fabricated and measured to confirm the simulation results. The fabricated prototype has a size of 1.1 × 1 × 0.58 λ 3 (at 30 GHz) and exhibits a measured impedance bandwidth in excess of 50%, from 24 to 40 GHz, a maximum measured gain of 14.2 dBi at 35 GHz, and a measured radiation efficiency of 93% at 30 GHz. INDEX TERMS 5G wireless networks, high gain magneto-electric dipole antenna, millimeter-wave antennas, printed ridge gap waveguide (PRGW), split-ring resonator (SRR).

“…To date, ISGW has been widely utilized for design of various microwave and mm-wave circuits, such as wideband couplers and combiners, 16,17 bandpass filters, [18][19][20] magneto-electric dipoles, 21,22 and slot antenna arrays, 23,24 etc. It has been found that ISGW based microwave and mm-wave devices have better performance than the counterparts of SIW circuits.…”

A theoretical method is presented by which characteristic impedance of integrated substrate gap waveguide (ISGW) is analyzed. The method is essentially based on a variational function for the transmission-line capacitance in Fourier-transformed domain with test/trial functions of charge density distribution, in which transverse transmission-line Green's function is used to facilitate the variational analysis. The presented method simplifies the determination of the potential distribution function which must satisfy the complex boundary conditions of the ISGW. Moreover, two types of ISGW, that is, twoand three-layer ISGW, working in K and E band are considered and analyzed by this method. Finally, the method is compared to the simulated using High Frequency Structure Simulator (HFSS) as well as measurements, and it is shown that the method leads to a very small inaccuracy compared to previously reported methods.
