The combination of simple membrane manufacturing process and the low Young's modulus of PU (EPU ≈ 30 MPa) are employed in the X-band antenna application. Membrane supported technology is used to reduce the influence of this high dielectric loss (tan δ ≈ 0.1 at 10 GHz) and gives higher antenna radiation efficiency (η ≈ 31.7 %). Besides, membrane deflection allows frequency tunability of the antenna up to 4.17 %. At last, the interest of patterning the metallic patch was discussed in order to increase actuation performance.","PeriodicalId":190987,"journal":{"name":"2014 16th International Symposium on Antenna Technology and Applied Electromagnetics (ANTEM)","volume":"29 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":"130083614","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 results show that 1) the variation of the phase differences is almost constant in certain second, 2) the errors between the ideal case and measured one are also almost constant value. These indicate the experimental system is capable of recording the signals without degrading the signal quality. If we figure out the error of phase difference of each channel in MBC when we measure the data of signals from the definite transmitting position, the accuracy of the direction in MBC will improve.","PeriodicalId":190987,"journal":{"name":"2014 16th International Symposium on Antenna Technology and Applied Electromagnetics (ANTEM)","volume":"85 2 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":"127433389","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}

We demonstrate a near field coupled volatile absorption pH sensor that can be used for wireless food quality monitoring. The sensor is based on a LC resonator whose resonant frequency changes with the concentration of acidic and/or basic volatiles in the sensor's surrounding environment. Tests with acetic acid and ammonium hydroxide sources show that the sensor can detect the presence of acidic and basic volatiles. The wireless sensor is passive and simple in design, making it an inexpensive, battery-less option for remote monitoring of food freshness during its shelf life.","PeriodicalId":190987,"journal":{"name":"2014 16th International Symposium on Antenna Technology and Applied Electromagnetics (ANTEM)","volume":"47 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":"122704222","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 small diameter circular waveguide feed has unequal radiation patterns in the principal planes, which are not suitable for prime focus reflectors. To make the pattern equalization, the dielectric rod is used inside the waveguide. It further reduces the overall diameter of the waveguide. The antenna is designed at 10 GHz, with dielectric constant εr = 2.5 and loss tangent 0.002. The numerical result shows that the radiation patterns are symmetrical in the principal planes with 10-dB beamwidths of 126°, cross-polarization level is -27.6 dB, and back lobe level is -31.4 dB, when the dielectric rod is extended by a 0.5 λ0 from the aperture with a rod radius a = 0.3 λ0.
