Switched parasitic array antennas are low cost, small sized and compact circular array antennas that steer beam in a desired direction by variation in switching pattern of parasitic elements. The proposed antenna design has an active center element, which is surrounded by several symmetrically placed parasitic elements. The designed antenna has a gain of 8 dB and is capable of 360 degrees beam steering in steps of 60 degrees each. Simulations are validated with results of the fabricated antenna. Antenna beam is steered by controlling parasitic elements. Future application of Electronically Steerable Parasitic Array Radiator (ESPAR) antennas and switched parasitic array antennas in next generation communication networks and methods for reducing size of the antenna are also highlighted.","PeriodicalId":253379,"journal":{"name":"2016 Loughborough Antennas & Propagation Conference (LAPC)","volume":"2018 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124672938","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}

Key to these architectures will be antennas that can both support very wide bandwidths and at the same time deliver high gain performance whilst maintaining omnidirectional characteristics.

Our approach specifically addresses the CP MPAs exited through dual inputs which are driven by branch line couplers of unequal power splits. Our procedure allows for the improvement of AR over the required range of operating frequencies. The procedure, implemented in a part with numerical optimization, is governed by a closed form formulas computing an appropriate unequal amplitude excitation of the MPA of interest. The required excitations are implemented with microstrip branch line couplers. Numerical optimization addresses the effect of coupling (through the feed) of the entire MPA-feed circuit. In this paper, the approach is illustrated with a numerical example of a probe-fed MPA. Moreover, our methodology has also been demonstrated to work for MPAs with open-end microstrip inputs. Numerical validation is carried out using full-wave simulations of the entire MPA-feed circuits.","PeriodicalId":253379,"journal":{"name":"2016 Loughborough Antennas & Propagation Conference (LAPC)","volume":"62 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132978051","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 indoor radio channel in an industrial environment exhibits a lot of multipath due to the prevalent metallic structures. In this research, an indoor radio channel is investigated in a severe multipath engine test bed environment. The study of this channel is undertaken for the applicability of a cost-efficient passive ultra high frequency radio frequency identification system capable of performing two dimensional localization of tagged objects in an engine test bed facility. The channel transfer functions were measured using a vector network analyzer. Vital channel characteristics investigated in this paper are the power delay profiles, the root mean square (RMS) delay and the power-ratio between the line of sight (LoS) and non-line of sight (NLoS) paths. The maximum RMS delay experienced is 47.1 ns and a minimum of 8.6 ns. The power-ratio values are appreciable for the majority of the LoS positions, but not satisfactory for the NLoS positions. Using this information, it will be helpful in analyzing the localization performance of a measurement-based system simulator or of a prospective hardware setup, in an engine test bed environment.","PeriodicalId":253379,"journal":{"name":"2016 Loughborough Antennas & Propagation Conference (LAPC)","volume":"43 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133107409","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 work managed with the design of a horn antenna, with fixed feeding power, to be used to irradiate the superficial layer of soils for a fixed depth. The soil was approximated using a transmission line model, i.e. a lumped electrical model. By this model, after having evaluated the relevant physical parameters, e.g. the dielectric constant (as a function of the soil water content), it was possible to evaluate the power absorption for the irradiated ground and, finally, the increase in temperature and its profile as a function of the irradiation time. Since the latter information is strictly connected to the heat transfer process occurring in the system, it is demonstrated the feasibility of the methodology here proposed to achieve difficult conditions for microbial and pathogens life and so an effective disinfection of the treated farmland.","PeriodicalId":253379,"journal":{"name":"2016 Loughborough Antennas & Propagation Conference (LAPC)","volume":"77 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133678432","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 RF evaluation modeling demonstrates the appropriateness to develop a high-performance and well-established design for the WiGig and 5G systems, along with the analysis of the RF characteristics.
