A granular tissue anomaly in one rat along with bleeding is observed after 15 weeks from the administration of the carcinogenic agent.

In this research, to obtain resonance frequencies for the multiband operation purposes, the main IFA and parasitic elements were investigated. More frequency bands obtained when the parasitic element placed beneath adjusted to the main IFA. The electromagnetic simulator WIPL-D based on Method of Moment used for numerical analysis. The performance of IFA extremely affected by the distance between the main horizontal element and the parasitic element. It found that the parasitic element coupled with the current on the conducting plane when the parasitic element located closer to the conducting plane. Consequently, the return loss bandwidth becomes narrower and the gain becomes a bit higher. The gain of the antenna is about 8.21 dB at band #3 (λ1.747), 7.43 dB at band #5 (λ2.967) and 8.82 dB at band #6 (λ4.023). The UHF and SHF channel receivers obtained from the calculation results. The proposed IFA are suitable for advanced wireless service (band #3), mobile phones, Bluetooth, maritime service, radiolocation service (band #5) and radars, mobile phones, commercial wireless LAN (band #6).","PeriodicalId":170627,"journal":{"name":"2019 IEEE Conference on Antenna Measurements & Applications (CAMA)","volume":"118 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114642170","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}

Angle of arrival (AOA) function is embedded into the array, enabling the radiation beam of the MIMO antenna to be directed precisely to incoming waves. There is a certain difficulty in terms of achieving the AOA antenna with a high accuracy because the AOA antenna is surrounded by a number of MIMO subarrays, which results in a strong electromagnetic mutual coupling. In this paper, an OTA experiment is carried out to confirm a method of reducing the EM coupling by means of controlling reactance loading. A significant reduction in the estimated error is confirmed by the reactance loading in a Rician propagation environment.","PeriodicalId":170627,"journal":{"name":"2019 IEEE Conference on Antenna Measurements & Applications (CAMA)","volume":"35 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123507891","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 minimum requirement of proposed antenna is having 400 GHz impedance bandwidth under −10 dB with working frequencies at 8.0 GHz-8.4 GHz. The proposed antenna will be developed in circularly polarized mode. Thus, the axial ratio must be under 3dB at the desired frequencies. To ensure the antenna design fulfilling all the minimum requirements, some techniques are implemented, for example, triangular truncation factor, ring slot with ellipse shape in the middle of patch, and sequential rotation with relative phases 0 degrees, 90 degrees, 180 degrees, 270 degrees. Then the radiator of antenna is formed by a circular shape. The proposed antenna could fulfil satisfied results. The impedance bandwidth of antenna is obtained 1.8 GHz (7.5 GHz-9.3 GHz). The simulated gain reached 12.5 dBic at the center frequency and the axial ratio bandwidth is 1.17 GHz (7.3 GHz-8.47 GHz).
