“…If we look into satellite communication applications, an antenna operating at a dual-band with a small frequency ratio is required. In [30], based on the advantage of aperture sharing a dual-band shared aperture antenna array for MMW bands(K-/Ka-bands) is proposed for low earth orbit (LEO) satellite communication. In another method, SIW CBSA is reported as operating in the dual-band by exciting two different modes in design [31][32][33][34].…”

Substrate Integrated Waveguide Cavity Backed Slot Antennas (SIW CBSA) are emerging candidates for planar Integrated Circuit (IC) technology in Millimetre-wave (MMW) bands. This peculiar antenna holds the advantage of conventional metallic cavity-backed antennas, with high gain, high front-toback ratio, and low cross-polarization level. SIW CBSA structures are the best option for planar integration with a low profile, and low fabrication cost in the design of MMW systems. This paper discusses various forms of SIW CBSA structures, their operating mechanism, and methods of improving their performance in terms of gain, bandwidth, size reduction, beamforming capability, and multiple bands of operation. From this discussion, we can select the antenna with the required characteristics in terms of gain, dual-band, and dualpolarization suited for present and future-generation applications.

“…In addition, the small wavelength of mmWave signals enables large antenna arrays to be deployed in areas as small as a cellphone or even a chip, achieving significantly high antenna gain for both the transmitting and receiving ends [2]. Thanks to the above benefits, mmWave communication has been regarded as one of the key enabling technologies in future wireless systems like 5G/6G cellular networks [3], unmanned aerial vehicle (UAV) communications [4] and satellite communications [5].…”

<p>While the millimeter-wave (mmWave) communica- tion is robust against the conventional wiretapping attack due to its short transmission range and directivity, this paper proposes a new opportunistic wiretapping and jamming (OWJ) attack model in mmWave wireless networks. With OWJ, an eavesdropper can opportunistically conduct wiretapping or jamming to initiate a more hazardous attack based on the instantaneous costs of wiretapping and jamming. We also provide three realizations of the OWJ attack, which are mainly determined by the cost models relevant to distance, path loss and received power, respectively. To understand the impact of the new attack on mmWave network security, we first develop novel approximation techniques to characterize the irregular distributions of wiretappers, jammers and interferers under three OWJ realizations. With the help of the results of node distributions, we then derive analytical expressions for the secrecy transmission capacity to depict the network security performance under OWJ. Finally, we provide extensive numerical results to illustrate the effect of OWJ and to demonstrate that the new attack can more significantly degrade the network security performance than the pure wiretapping or jamming attack. </p>

“…In recent years, low profile array antennas have been extensively used for communication applications such as 5G or SATCOM applications. [1][2][3][4][5] Microstrip array antennas are an excellent example of flat structure compared to parabolic antennas, but they have disadvantages of having high loss value due to substrate material, radiation, or surface roughness. Although there had been studies with subarrays of microstrip antennas integrated with rectangular waveguide feed networks to minimize losses, these solutions still do not meet the required performance for complex communication applications.…”

Using electrically large antennas for array applications may cause grating lobes and this can change the array pattern. To achieve a low side lobe level for boresight pattern for linear or planar array antennas, in the literature it is seen that the common method is the use of feeding each antenna with some amplitude distribution and keeping the distance between the antennas less than a wavelength.However, in this study the distance between the antennas is chosen to be greater than a wavelength. Therefore, the common methods cannot be used. To achieve a low side lob level in the radiation pattern for an array of antennas composed of antennas with a distance greater than one wavelength.
