Distributed antenna systems (DAS) being a choice to maintain reliable 100 Gbit/s wireless links are employed in this paper to study the THz coverage in the presence of multiple humans. The study environment is a non-cubic 3D office room model of 7 x 7 x 3 m 3 at our Institute of Digital Signal Processing (DSV) as shown in Fig. 1 (a) . For this purpose, we employ up to five 3D models of both male (1.76 m high) and female (1.70 m high) clothed bodies designed in a 3D computer graphic software tool and then imported as an object (computation intensive with 48,090 polygons/faces) to ray-tracing tool. Upon entering the office room, the human models follow certain trajectories till they reach their respective workplaces. Moreover, the gait motion phases (in a total walking cycle) along with a predefined step size for each human body model is taken into account. Assessing the coverage, the transmitting access point antenna is placed at different locations (i.e., middle and all four corners) in the room and the coverage maps are then generated at two chosen heights of the receiving antenna grid as depicted in Fig. 1 (b) . The chosen RXPs are 0.25 m from the floor when taking into account the worst-case coverage whereas in case of table top terminals these possess a height of 0.75 m. There are 72,900 receiver points (RXPs) covering the entire office room, required to study the frequency selective fading. The details of the human body models together with the antenna positions in addition to simulation parameters as well as material parameters at 300 GHz will be conferred in the full paper.","PeriodicalId":253455,"journal":{"name":"2021 IEEE-APS Topical Conference on Antennas and Propagation in Wireless Communications (APWC)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-08-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128192940","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Common theoretical RF propagation models such as the Two-ray Reflection Model or models based on solving Maxwell’s equations using the parabolic equation methods can reliably generate such predictions only in the far-field of the antennas, where antenna gain patterns can be used with the models. This paper will examine a model derived from Maxwell’s equations. The model solves the problem of electromagnetic propagation over a half-space that applies to both the near- and far-field. The model’s theoretical equations are corroborated with field measurements. The paper concludes with recommendations on how the propagation characteristics of RF signals in the near-field can be used to mitigate interference from earth station transmitters to commercial base station antennas.","PeriodicalId":253455,"journal":{"name":"2021 IEEE-APS Topical Conference on Antennas and Propagation in Wireless Communications (APWC)","volume":"76 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-08-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126215431","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The antenna array is intended for Vehicle-to-Vehicle (V2V) systems and can be easily installed on moving platforms. The filter is etched from the ground plane of the antenna mounting structure and consists of 25 mm × 15 mm outer rectangular frame that has a width of 0.5 mm. This frame encloses three parallel slots, 24.21 mm in length, inserted symmetrically inside the frame between the coaxial-fed monopole antennas. The slots are 0.5 mm in width and uniformly separated by 0.25 mm. The two monopoles have a height of 17.35 mm each, a diameter of 1.27 mm, both are separated by eight mm, which corresponds to λ/10.56, where λ is the free-space wavelength at 3.55 GHz. The monopoles and the filter are placed on a 90 mm × 90 mm × 3.175 mm RO5880 substrate with a dielectric constant of 2.2 and a loss tangent of 9 ×10 −4 . The filtantenna array provides 26.6% matching impedance bandwidth below −10 dB centered at 3.84 GHz and 18% mutual coupling suppression bandwidth below −20 dB centered at 3.4 GHz. Figure 1 shows the simulated scattering parameters of the proposed filtantenna array design (decoupled antenna array) compared to the same antenna array without the printed-circuit filter (coupled antenna array) The operating bandwidth of the decoupled antenna array over which the matched impedance is below −10 dB and the mutual coupling is below −20 dB is 370 MHz extending from 3.33 GHz to 3.7 GHz. It can be seen that the matching impedance of the coupled array is above −10 dB while and the mutual coupling of the coupled antenna array has been reduced from −5.2 dB to −34.2 dB","PeriodicalId":253455,"journal":{"name":"2021 IEEE-APS Topical Conference on Antennas and Propagation in Wireless Communications (APWC)","volume":"20 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-08-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127790165","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
