In this paper, a compact quad-port Rhombus-Shaped MIMO Patch (RSMP) antenna with a complete ground structure has been designed for dual-band wireless applications. The RSMP antenna has a common patch configuration and resonates at 12.9 GHz and 16.5 GHz with the reflection coefficients of −17 dB and −25.7 dB, respectively. A rhombus-shaped slot is etched from the patch to generate dual-band frequencies. Microstrip feed lines are connected to the common patch and are used to improve the overall performance of the RSMP antenna. The RSMP antenna has gains of 9.62 dBi and 9.98 dBi at resonating frequencies. The bandwidths of the proposed MIMO antenna model are 300 MHz and 350 MHz, respectively. The proposed RSMP antenna model was fabricated and tested with the vector network analyzer Keysight N9917A for validation. The simulated and measured results for the gain, reflection coefficients, surface current distribution, radiation pattern, envelope correlation coefficient (ECC), diversity gain (DG), total active reflection coefficient (TARC), and channel capacity loss (CCL) are compared, and they are agreed well for wireless applications at Ku-band for broadcasting communications.

As technology advances, notable scientific research accomplishments have been made. Terahertz (THz) waves have been seen to have endless potential applications that could further improve the current limitations of other frequency bands for imaging applications. Currently, THz waves display great potential in various applications due to their noninvasive and nonionizing features. However, the THz band has not been technically well established. This paper focuses on a comparative survey of the current methods applied in THz imaging in the field of medical and industrial security applications. Different types of methods, findings, advantages, and challenges of surveys ranging from 2016 to 2021 were discussed for both medical and industrial security applications to deepen the understanding of the latest trends, research, and technologies to have efficient THz imaging systems.

In recent times rectangular patch antenna design has become the most innovative and popular subject due to its advantages, such as being lightweight, conformal, ease to fabricate, low cost and small size. In this paper design of aperture coupled microstrip patch antenna (MSA) on high index semiconductor material coupled with micromachining technique for performance enhancement is discussed. The performance in terms of return loss bandwidth, gain, cross-polarization and antenna efficiency is compared with standard aperture coupled antenna. Micromachining underneath of the patch helps in to reduce the effective dielectric constant, which is desirable for the radiation characteristics of the patch antenna. Improvement 36 percent and 18 percent in return loss bandwidth and gain respectively achieved using micromachined aperture coupled feed patch, which is due to the reduction in losses, suppression of surface waves and substrate modes. In this article along with design, fabrication aspects on Si substrate using MEMS process also discussed. Presented antenna design is proposed antenna can be useful in smart antenna arrays suitable in satellite, radar communication applications. Two topologies at X-band are fabricated and comparison between aperture coupled and micromachined aperture coupled are presented. Index Terms—Microstrip Patch Antenna, Aperture Coupled, Micromachining, High Resistivity Silicon
