To verify the design concept, a prototype planar monopulse array operating at 5.7 GHz is designed and fabricated, and Keysight microwave kits is configured as down conversion to receive the signals from array.

Additionally, using multiple antenna feeds extends the high-efficiency region of the rectifier, which in turn, allows for high DC output power and high efficiency simultaneously. A proof-of-concept two-feed rectenna is designed and tested at 960 MHz. It achieves a peak efficiency of 64.5% and a combined DC output voltage of 1.72 V at an input power density of $mathbf{2.3} mu mathbf{W}/mathbf{cm}^{2}$, demonstrating state-of-the-art RF energy harvesting performance.","PeriodicalId":363264,"journal":{"name":"2023 IEEE Texas Symposium on Wireless and Microwave Circuits and Systems (WMCS)","volume":"19 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-04-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124952504","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 is due to coupling from the WPT system to a natural or characteristic mode of the EV which acts as vertical electric dipole which, in turn, excites the $text{TM}_{01}$ SWF. However, it is not obvious how the circular couplers, which have been presumed to behave as magnetic loops, couple to TM (electric) vehicular characteristic modes. This coupling mechanism is explored in detail here. We show here that it is the turn-to-turn voltage drop which produces a conservative electric field (to be distinguished from the solenoidal electric field predicted by Faraday's law) which excites the vehicle like a coaxial aperture. That is, at the most idealized level, the vehicle acts like a conducting convex, object, similar to a sphere or ellipsoid located just above a coaxial aperture. It also occurs in the absence of common-mode (CM) excitation due to imbalance in the primary-side source, which is typically an H-bridge. The coaxial aperture alone would excite primarily a $text{TM}_{02}-R$ SWF and it can be shown that a $text{TM}_{02}-R$ source, in place of the WPT system under the vehicle, gives similar results, strongly exciting the $text{TM}_{01}$ SWF. The $text{TM}_{01}$ SWF is problematic as it excites the HF ground wave potentially presenting a source of RF interference. The forgoing assertions were verified using simulations of the near and far fields with HFSS and FEKO.","PeriodicalId":363264,"journal":{"name":"2023 IEEE Texas Symposium on Wireless and Microwave Circuits and Systems (WMCS)","volume":"37 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-04-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121081766","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}

Qorvo TGF2977 GaN HEMT transistor has been used for the proposed design since it is capable of operating in the desired UWB frequency range from DC to 12 GHz. An impedance matching technique has been proposed in this paper so that when the matching network elements are translated through the T-line elements, the impedance of the matching network incorporating the T-line elements is matched to the optimal source and load impedances of the transistor. An analytical model of the microstrip T-line has been developed in this paper so that proper impedance matching can be achieved by tuning and controlling the width of the T-line elements. The desired S-parameter response can be obtained by using this technique so that the target performances of the PA can be achieved. The proposed PA is chosen to operate in the class-C mode since this mode of operation can achieve a very high efficiency. The designed PA is capable of achieving a gain of 14.34 dB and has a $-3dB$ gain bandwidth of 3.03 GHz (51% fractional bandwidth) from 4.22 – 7.25 GHz. The PA is able to generate the highest output power of 34.9 dBm $(3.1W)$ at the $P_{1dB}$ of 22 dBm input power at 6 GHz frequency. At the same frequency and the $P_{1dB}$ input power, the proposed PA is able to achieve a power added efficiency (PAE) of 37.1% while the highest PAE of 45.6% is achieved at the 28 dBm input power.","PeriodicalId":363264,"journal":{"name":"2023 IEEE Texas Symposium on Wireless and Microwave Circuits and Systems (WMCS)","volume":"30 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-04-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"120973734","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}
