A simple model that accounts for inter-element mutual coupling is presented which explains the false polarization leakage in Stokes Q (“false Q”) seen when the array is scanned away from zenith in the principal planes. On these planes the model predicts current imbalance in the X (E-W) and Y (N-S) dipoles and hence the false Q. More sophisticated models intended to calibrate actual observation data will be briefly discussed.","PeriodicalId":190987,"journal":{"name":"2014 16th International Symposium on Antenna Technology and Applied Electromagnetics (ANTEM)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-07-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128491267","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}

Simulation results in Ansoft HFSS indicate that its 10 dB impedance bandwidth is 2.95 GHz from 22 GHz to 24.95 GHz, the maximal peak realized gain is 18 dBi at 24.4 GHz and 3 dB gain bandwidth is 2.15 GHz from 23.03 GHz to 25.18 GHz with broadside radiation patterns at 24 GHz.

It is shown that these MTSs may exhibit an inductive or capacitive reactance depending on the connection status of the patch vertexes. A simple analytical model is derived to predict the dispersion curve of the supported surface waves (SWs). Furthermore, it is shown that connecting or disconnecting the metal patches along a given path allows for a confinement of the SWs on such a path. This property opens the possibility of realizing reconfigurable transmission lines by controlling the status of patch connections through miniaturized switches.","PeriodicalId":190987,"journal":{"name":"2014 16th International Symposium on Antenna Technology and Applied Electromagnetics (ANTEM)","volume":"36 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-07-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124129022","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 uniqueness of this antenna design is due to its simple structure and feeding mechanism with low manufacturing cost.

The -10 dB S11 bandwidths for the first band is from 2.8 to 3.1 GHz and for the second band is from 3.45 GHz to 3.61 GHz. The radiation patterns at these frequency bands are good with low cross-polarization and back lobe levels.
