Top coupled filter topology with transmission zeroes is selected to give low insertion loss (IL) < 1.8 dB in passband 3.3 ∼ 3.8 GHz, with >30dB attenuation at 2.7 GHz and 4.9 GHz. Therefore, this design can effectively filter out adjacent ISM, 5G NR n41, and WLAN bands. Model correlation is verified with Silicon IPD wafer measurements.

High-precision instrumentation is required to address these challenges and to appraise innovative designs as the field enters into the millimetre wavelength frequencies. Near-field measurements show evidence of energy back-propagation stemming from complex interactions within the electromagnetic field. To control the evolution of a high-frequency signal in the reactive near-field zone, an enhanced knowledge of the interaction between electric E and magnetic H fields is essential. Aprel's 5G near-field probes have been developed to measure the field vector distributions at frequencies from 10 GHz to 110 GHz in close proximity to a device. The presented E and H probes are able to discern the 360-degree field patterns at each measurement point and to quantify the field vector amplitude and its direction within the evaluation plane. The results of these measurements can provide information on the power density, backscattering effect, antenna gain and directivity, beamforming, and much more.","PeriodicalId":193359,"journal":{"name":"2018 IEEE 19th Wireless and Microwave Technology Conference (WAMICON)","volume":"84 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-04-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116472624","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}

This paper presents an uncoordinated non-orthogonal random access protocol, which is an enhancement to the recently introduced Slotted Aloha-NOMA (SAN) protocol that provides high throughput, while being matched to the low complexity requirements and the sporadic traffic pattern of IoT devices. Under ideal conditions it has been shown that Slotted Aloha-NOMA (SAN), using power-domain orthogonality, can significantly increase the throughput using SIC (Successive Interference Cancellation) to enable correct reception of multiple simultaneous transmitted signals. For this ideal performance, the enhanced SAN receiver adaptively learns the number of active devices (which is not known a priori) using a form of multi-hypothesis testing. For small numbers of simultaneous transmissions, it is shown that there can be substantial throughput gain of 5.5 dB relative to slotted Aloha (SA) for 0.07 probability of transmission and up to 3 active transmitters.","PeriodicalId":193359,"journal":{"name":"2018 IEEE 19th Wireless and Microwave Technology Conference (WAMICON)","volume":"29 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124850050","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 PA operates at 1.227GHz-the L2C second civilian GPS signal operation frequency. Harmonic controlling matching networks are designed to achieve class-F−1 current and voltage waveforms at the intrinsic drain. High efficiency is achieved by using harmonic source and load-pull tuning to design the input and output matching networks. The fo matching is performed using a low-Z single-section transformer. Harmonic terminations for 2fo and 3fo are realized using shunt transmission lines placed at optimal offsets from the drain. These matching networks are fine-tuned using a network analyzer. The overall PA performance was tested under different DC biases with swept input power. The best performance is achieved with a bias of Vds=50V, Vgs=−3V and Pin=32dBm where the PA exhibits 133W output at 42% power-added efficiency (PAE).","PeriodicalId":193359,"journal":{"name":"2018 IEEE 19th Wireless and Microwave Technology Conference (WAMICON)","volume":"10 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126439024","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 work leveraged an Arduino platform with a XBee wireless module and compared performance (i.e., link reliability) when a baseline monopole antenna was used versus a prototype, 3D printed tripolar antenna system. The testing was conducted by placing both antennas inside of a compact reverberation chamber. We also compared empirical data with simulated data and showed that for both cases, the tripolar antenna system performed approximately three times better than the monopole antenna. Finally, we conducted tests under dynamic conditions where the wireless node switched, at various rates, between the three antenna elements, choosing the best option to send data packets and results showed that the tripolar antenna can mitigate the high multipath effect with 95% successful packet delivery.","PeriodicalId":193359,"journal":{"name":"2018 IEEE 19th Wireless and Microwave Technology Conference (WAMICON)","volume":"43 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134137052","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}
