“…The first resonance at 19.5 GHz is caused by the SIW cylindrical cavity. As demonstrated in [32], a cylindrical cavity can act as an aperture radiator when it operates with TM 110 mode. For a cylindrical cavity with a radius of r 1 and a height of h, the resonant wavelength of TE mnp and TM mnp modes is formulated by [33] 2r 1…”

This paper presents a new design of a differentiallyfed substrate integrated planar antenna array with dualpolarization. Compared with the traditional dual-polarized antenna arrays, the proposed array antenna has the advantages of simple configuration, high cross-polarization discrimination (XPD) and high gain. 2 × 2-element subarray design with a vialoaded crossover structure is used, which reduces the complexity of the array antenna. The operation bandwidth is improved by generating three resonances in the subarray. An 8 × 8 antenna array is designed, prototyped and tested to exemplify its potential applications in large dual-polarized antenna arrays. A planar orthomode transducer is used to achieve differential excitation for the antenna array. The measured results show that the proposed antenna array has an impedance bandwidth of 19.2-20.7 GHz for |S 11 | < −10 dB and port isolation higher than 20 dB. The array antenna exhibits a high XPD of 43 dB and a flat gain about 22.2 dBi within the bandwidth.

“…Moreover, since the extensive study by Ebbesen et al [10] reporting extraordinary optical transmission (EOT) through twodimensional (2D) hole arrays, related studies on subwavelength apertures have become an active area of research in electromagnetism and optical physics [11][12][13][14][15][16][17][18][19][20][21][22]. A slot in a thick plate creates a waveguide structure, and the transmission characteristics of this structure have been studied [23][24][25][26][27][28][29][30]. Resonance transmission (RT) occurs in the narrow slot of a thick plate (waveguide structure) above the cutoff [30].…”

This study presents the transmission of electromagnetic waves through a partially covered narrow slot on a thick conducting screen when a plane wave is incident on the slot. The slot in the thick plate that creates a waveguide structure mainly causes resonance transmission (RT) above the cutoff; moreover, a weak RT (WRT) phenomenon also occurs. However, the WRT phenomenon has not been considered. In contrast, a partially covered slot in a thick plate creates a partially slotted waveguide (PSW). In the PSW structure, when the slot length is below the half-wavelength, WRT mainly occurs, even if the waveguide is above the cutoff, and RT does not occur. The amplitude of this WRT depends on the length of the slot and plate thickness. In addition, the transmission cross section (TCS) patterns with symmetry and asymmetry are presented with resonance states to consider the transmission mode in more detail.

“…It is observed that the resonance condition of the antenna also depends on the dimension of the strip and its location. The CBS antennas with cylindrical and hemispherical cavity are analyzed in [4][5]. In [6], study of CBS antenna with annular slot has been presented.…”

In this paper, design of broadband microstrip line fed cavity backed slot antenna with very small cavity height of 0.08 lambda is proposed. The antenna is designed for 1.8 GHz frequency band with wider beam coverage in E-plane. Parametric analysis of antenna is carried out to optimize antenna design for smaller cavity height, broad bandwidth and wider beam coverage. The radiation characteristic of antenna for different sizes of ground plane is analyzed in detail. Measured results of antenna with different ground plane sizes are presented. The Antenna has VSWR <2 bandwidth of 18% and maximum gain of 7.2 dBi with wide beam coverage in E-plane.
