With a footprint of 0.23 o, 0.120 o, and 0.0007 o, where o is the lowest resonance wavelength, the antenna is relatively tiny. The antenna is built from a straightforward geometrical structure consisting of a W-shaped serpentine structure supplied by a microstrip line and a partial ground plane utilizing the Defected Ground Structure (DGS) technology in order to achieve wide operational bandwidth. In order to boost resonance, an additional capacitor was inserted between the slots, creating a portable dual-band antenna. Several performance metrics' findings and the ones that had been measured were compared. The antenna's potential for rigid and flexible electronics is increased by its good size, bandwidth, gain, and radiation pattern.","PeriodicalId":246624,"journal":{"name":"2023 International Microwave and Antenna Symposium (IMAS)","volume":"35 2 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-02-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123530232","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 suggested antenna is made up of two radiating patches that work together to operate in the 5.8 GHz WLAN and 3.5/5.5 GHz WiMAX bands. The four element MIMO antenna with size of 64×64 mm2 is fabricated on a 1.6 mm in thickness FR-4 sheet with a dielectric constant of 4.4 and a loss tangent of 0.02. To boost the performance of the structure in respect to operating bandwidth; a parametric study was done based on FDTD technique resulting in an optimized dual band antenna. Moreover, a four element MIMO configuration separately 50Ω-fed is considered, and the prototype is fabricated and measured using VNA. Spatial diversity is introduced in the MIMO configuration resulting in good isolation without employing the known decoupling structures and techniques. The measurements reveal that the system operates on two desired bands with a coupling of less than -15 dB between the different elements. In addition, the MIMO metrics are analyzed and found to meet the practical standards of: ECC < 0.04, DG > 9.80, -12 dB < MEG < -3 dB, TARC < -10 dB, and CCL < 0.4 bits/s/Hz over the concerned bands.","PeriodicalId":246624,"journal":{"name":"2023 International Microwave and Antenna Symposium (IMAS)","volume":"118 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-02-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131528578","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 system offers no spectrum reuses and there is no co-channel interference between beams as they are isolated with the code orthogonally, therefore the system throughput increases without scarifying any resources or increasing neither system complexity nor latency. The presented work uses the affordable polarization resource at the user terminal side to increase the capacity in each beam by using both vertical and horizontal polarization support with the conventional multiple accessing techniques between users in the beam. Results show the superiority of proposed scheme compared to current state of- the art in cases of practical interest.","PeriodicalId":246624,"journal":{"name":"2023 International Microwave and Antenna Symposium (IMAS)","volume":"28 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-02-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114378121","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 rush order for many applications and modern technologies in radio frequency systems to be low cost and more compact is enticing more awareness. In this paper, a new power divider/combiner is introduced as one device instead of using two devices by achieving equal return loss for input and outputs ports side by side with the insertion loss. The proposed design is developed by replacing the third half wavelength Transmission Line (TL) of the traditional Gysel Power Combiner/Divider (GPCD) by a microstrip Chebyshev bandpass filter with a center frequency of 1.5 GHz to widen the operating bandwidth. The robustness of the suggested design is elucidated by examining measurement and simulation results and comparing them with other state-of-the-art designs. The proposed GPCD design provides efficient operation in the L-band with equivalent fractional bandwidth of 69 % for all S-parameters. This demonstrates that the introduced GPCD design can be efficiently utilized in wideband and low-cost microwave applications.","PeriodicalId":246624,"journal":{"name":"2023 International Microwave and Antenna Symposium (IMAS)","volume":"271 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-02-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123118516","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}

As the piston moves, it changes the distance between the mirrors, which in turn changes the resonant cavity's length and the wavelength of the light that is amplified or suppressed. By measuring this change in wavelength, the sensor can determine the piston's position and thus the cylinder's stroke.
