The U-shape inside patch are implemented in order to increase the bandwidth and gain. The proposed antenna is simulated using HFSS software and then printed on the FR4 substrate with thickness of 1.6 mm and permittivity of 4.4.

The results indicate that the boron gallium nitride back barrier may restrict the two-dimensional electron gas (2DEG) in the channel region and efficiently suppress the short channel effects. The BGaN back barrier HEMT with just a 2% B-component greatly improves the device’s analog and RF performance over a normal GaN buffer HEMT such as transconductance (0.15 S), intrinsic gain, early voltage (4.24 V), cut-off frequency (141 GHz) GFP (356 GHz), GTFP (4.6 THz), and transconductance frequency product (6.5 THz). Therefore, the device with a BGaN back barrier has considerable potential for use in applications requiring extremely linear devices that operate at high frequencies and high gain powers.","PeriodicalId":171480,"journal":{"name":"2022 IEEE International RF and Microwave Conference (RFM)","volume":"144 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":"133946638","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}

Some of these devices are high-end Users Equipment (UEs) and can process the whole bandwidth allocated by the base station (gNB). However, there are UEs that are not able to support the large bandwidths. To provide service to all devices in the network, a new concept called bandwidth part (BWP) introduced in the 5G NR systems. With the active BWP, the gNB can allocate only a segment of the bandwidth to these devices. However, activating BWP, might change the center frequency from the UE point of view. This leads to phase rotation that leads to the UE not able to attach to the gNB. This paper first gives an overview of the proposed phase compensation technique in the 5G NR and then presents some simulation and experimental results to validate the functionality of the proposed technique.","PeriodicalId":171480,"journal":{"name":"2022 IEEE International RF and Microwave Conference (RFM)","volume":"9 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":"130883279","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 QRHA which has quadratic ridge profiles is applied as it offers a wide bandwidth and dual polarization characteristics. The used QRHA is fabricated using 3D printing technique based on polylactic acid (PLA) material. The data acquisition process is performed by using a set of QRHA as transmitter and receiver antennas. A tree trunk with a hole in the center is employed as a model for object examination, whereby it is placed in between the transmitter and receiver antennas. The result of data acquisition process formed as transmission coefficient (S21) is then processed for further reconstruction purpose. From the implementation, it shows that the magnitude of S21 obviously decreases as the presence of object between the antennas. In addition, the measured S21 has also the similar trend to the simulated one for varied object positions.","PeriodicalId":171480,"journal":{"name":"2022 IEEE International RF and Microwave Conference (RFM)","volume":"48 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":"115878071","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}
