The use of PET (Polyethylene Terephthalate) material in the substrate gives the flexibility to form a low cost antenna that can work for a range of frequencies. The antenna is flexible and can be used as biological sensors. The use of transparent PET material can have several advantages in terms where transparency is required. The antenna is designed to resonate in K band region. Simple patch antenna is designed with a split ring slot in between to reduce the bandwidth and improve the selectivity, as well as sensitivity of the antenna suitable for controlled reconfigurability in the frequency. At room temperature, antenna resonates at 23.8 GHz, with a gain of 6.16dBi and radiation efficiency of 92.06%. As the temperature increases from room temperature to 100°C, the frequency shifted from 23.8 GHz to 22.66 GHz. Antenna shows a dual band characteristic with equivalent significance of temperature on both the frequency.","PeriodicalId":410781,"journal":{"name":"2022 IEEE Wireless Antenna and Microwave Symposium (WAMS)","volume":"39 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-06-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115157332","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}

With a fractional bandwidth of around 150%, this proposed layer provides wideband rejection across the entire band ranging from 3.5 GHz to 25 GHz.

The expression for the Green's function in the frequency and time domain is obtained for a wedge with Neumann's boundary conditions. The image-based representation of reflections is incorporated to obtain a modified response which is valid and not limited to the incident angle, frequency, and observation location. It will be shown that the image-based expression for exact scattering is the simplest form, consists of six terms and an integral for diffraction. In this study, the exact decay in amplitude and propagation delay of the reflected wave is explained. It is shown that one does not need stationary phase approximation to obtain the response in the asymptotic limits.","PeriodicalId":410781,"journal":{"name":"2022 IEEE Wireless Antenna and Microwave Symposium (WAMS)","volume":"140 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-06-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116458256","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}

A dual-reflector antenna using axially displaced ellipsoid (ADE) sub-reflector fed with a wideband quad-ridged horn provided Ku-band transmit, Ku-band receive, K-band receive and Ka-band transmit frequencies using a high performance quadraplexer. The main reflector is made of six identical petals that can be quickly assembled and disassembled in the battle field. The antenna is assembled on a light-weight 2-axis gimbal to provide beam scanning over +/− 900 in elevation and 3600 in azimuth. The antenna / gimbal combination is then mounted on a tripod structure for field operations and uses commercial off the shelf (COTS) components and 3-D manufactured parts to minimize cost and weight.

But Re-configurable Intelligent Surfaces (RIS) paves a path for it by applying the concept of meta-surfaces. In this paper, we propose a means by which radio-frequency waves could be controlled electronically using a re-configurable meta-surface, which consist of 3 layers of metal over substrate. Each surface is an array of 8 cells and it is designed to operate in the 3-4 GHz. The ON and OFF state can be ideally achieved using any RF switches like PIN diodes. In this paper, the concept is proved using metal strips between the cells for ON and removing it for OFF state. In ON state, the meta-surface is designed to reflect the EM wave completely, just like a perfect metal. In OFF state, the waves in the designed frequency band passes through the structure. The simulation and measured results shows a 200 MHz transmission bandwidth. We have fabricated the designed meta-surface and verified the transmission and reflection properties in a S -band wave guide.","PeriodicalId":410781,"journal":{"name":"2022 IEEE Wireless Antenna and Microwave Symposium (WAMS)","volume":"27 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-06-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123484621","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}
