However, in radiofrequency and microwave region, circular antenna array, as the common method to generate vortex beam with multiple OAM modes, its complex feeding network increases the difficulty of fabrication and integration [2] . Through adopting the ability of metasurface to accurately manipulate the EM properties, versatile OAM modes can be stimulated by metasurface-assisted antennas [3] . In this paper, a highly efficient metasurface-engineered antenna is proposed to generate vortex beam carrying five distinct integer and fractional OAM modes in microwave region, the mechanism schematic is shown in Figure 1a . The integer and fractional OAM with topological charge l =1, 1.5, 2, 2.5, 3 can be separately generated in total, where the combination of polarization states (left-handed circular polarization, LHCP; x-linearly polarization, x-LP; right-handed circular polarization, RHCP) of the transmitting antenna and receiving probe acts as the key to alter the output OAM modes.","PeriodicalId":422168,"journal":{"name":"2022 IEEE-APS Topical Conference on Antennas and Propagation in Wireless Communications (APWC)","volume":"30 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-09-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133230887","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}

Microstrip antennas (MSAs) are commonly used for various applications such as mobile communication, broadcasting, and radars because MSAs have advantages of small size, low profile, light weight, and low manufacturing cost. Multi -ring microstrip antennas (MR -MSAs) have been proposed by the authors as a multiband planar antenna [1] . The MR-MSA is composed of a double-layered dielectric substrate; multiple ring patches are concentrically arranged on the top substrate and an L-shaped feeding probe (L-probe) [2] , [3] to excite the ring patches is situated on the bottom substrate. The MR-MSA provides excellent multiband performance because the resonant frequencies are flexibly designed with stable unidirectional radiation patterns. Linear or circular polarization of each resonant frequency can be also designed individually. Only disadvantage is narrow bandwidth characteristic when a thin dielectric substrate is used for the MR-MSA. On the other hand, the MR-MSA fed by an L-probe with a thick dielectric substrate for single- and dual-band operations has been presented [4] . The wideband MR-MSA for a single-band operation which consists of one ring patch and an L-probe exhibits approximately 45% fractional reflection bandwidth of less than –10 dB reflection, where a thick double-layered substrate with a thickness of approximately 0.15 wavelengths at the center frequency and with a relative dielectric constant of 2.6 is used. One of the wideband MR-MSA fed by an L-probe is to use the double-layered dielectric substrate.","PeriodicalId":422168,"journal":{"name":"2022 IEEE-APS Topical Conference on Antennas and Propagation in Wireless Communications (APWC)","volume":"20 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-09-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121032276","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 key challenge to FD is self-interference (SI): a node’s transmitting signal generates significant interference to its own receiver. Several prior works have shown the potential to reduce SI and build FD radios but they are limited to Sub-6 GHz systems. In this paper, we focus on the emerging mmWave systems and the potential reduction in SI through antenna design. The increased bandwidth requirements of mmWave systems necessitate the use of higher bandwidth antenna designs such as stacked patch antennas for transmission (Tx) and reception (Rx). Specifically, we investigate the optimal placement of a mushroom electromagnetic band gap (EBG) structure for maximum Tx and Rx isolation (coupling reduction) in a 4-layer substrate stacked patch antenna design targeted for small mobile devices. Through extensive simulations we show that top&inner layer EBG (\"stacked\") provides more than 80 dB of isolation at 28 GHz frequency, which is 20 dB more isolation than either top or inner layer EBG. We also show that the frequency bandwidth and gain of the stacked patch antenna are not negatively impacted due to the EBG integration.","PeriodicalId":422168,"journal":{"name":"2022 IEEE-APS Topical Conference on Antennas and Propagation in Wireless Communications (APWC)","volume":"18 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-09-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125296664","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}
