The proposed array antenna is fabricated using two layers of FR4 epoxy dielectric substrate with the total dimension of 0.805λo × 0.417λo × 0.014λo. From the experimental characterization, the result shows that the proposed array antenna operated at the center frequency of 1.275 GHz with the –10 dB impedance bandwidth of 27 MHz. Moreover, the fabricated array antenna produced a symmetrical radiation pattern with the front-to-back ratio of 6.41 dB, in which this result is comparable to the simulated one with the front-to-back ratio of 10.45 dB.","PeriodicalId":171480,"journal":{"name":"2022 IEEE International RF and Microwave Conference (RFM)","volume":"14 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-12-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114399738","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}

Millimeter wave (mmW) technology a candidate 5G technology requires special and well-designed antennas to power its transmissions. Microstrip patch antennas (MPA), which are popular due to their low profile, lightweight, tiny size, low cost, and simple fabrication, could meet these requirements. The proposed MPA is designed and fabricated on a Rogers RT Duroid 5880 substrate with a dimension of 6.3 × 7.24 × 0.5 mm3, a dielectric constant of 2.2 and a tangent loss of 0.0009. The proposed MPA at 28 GHz with a measured return loss of -21.37 dB, measured impedance bandwidth of 2.685 GHz and directivity of 10.02 dBi.

The perturbation method, in which the dielectric characteristics of the resonator affect Q-factor and resonance frequency, is used in this study to address the weakness of this technique. For material characterization of solid and liquid samples, this proposed sensor worked at 2.5GHz in the 1GHz to 4GHz range. These sensors were built on a substrate of RT/Duroid Roger 5880 with a dielectric constant of 2.2, a loss tangent of 0.0009, and a copper thickness of 0.00175mm. As a result, at 2.5GHz, this square split ring resonator (SSRR) sensor produces narrow resonance, low insertion loss, and a high Q-factor value of 430. As a result, the SSRR sensor's sensitivity is 98.59%, which is higher than earlier investigations. This evidence supports the proposed sensor's application as a material characterization tool, particularly for identifying material properties.","PeriodicalId":171480,"journal":{"name":"2022 IEEE International RF and Microwave Conference (RFM)","volume":"34 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-12-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126700078","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}

One of the important factors considered in any amplifier design is efficiency, as communication technology becomes more complex, an out of phase signal in a double ended amplifier, could result in drastically reduced efficiency. Outphasing can be used to alleviate this problem. The result shows that the outphasing technique can maintain the efficiency at above 70% even when the input signal becomes increasingly out of phase and the output signal is decreased. The outphasing technique shows promise as it can be used in high efficiency applications such as electric car, wireless charging station.","PeriodicalId":171480,"journal":{"name":"2022 IEEE International RF and Microwave Conference (RFM)","volume":"234 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-12-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124818219","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}
