The design of the tag antenna adopts T-match-based RFID tag concept to develop a compact and high bandwidth antenna at UHF range between 860 MHz to 960 MHz. In the wearable RFID tag antenna, copper core electro-textile fabric is acting as the radiating element and polyester fabric with a dielectric constant of 2.1 used as the substrate (non-conductive layer). The performance of the antennas is compared in terms of its reflection coefficient, impedance matching and design complexity. Among the challenges in designing a UHF RFID tag antenna is the complexity in integrating IC chip into the tag. During operation, signal from RFID reader will activate the IC chip and the backscattered signal containing information will be sent to the reader. Therefore, to allow optimum operation, the impedance value of the antenna must match with the IC’s impedance to ensure maximum power transfer between the antenna and the IC chip. The first antenna design consists of T-match with meander method to produce various tunable antenna features while the second design only features a T-match based RFID design with less antenna geometric structure. The second antenna design is observed to have better reflection coefficient and impedance matching compared to the first antenna design. The data from this simulation is useful to determine fabrication complexity in designing UHF RFID tag antenna tag based on electro-textile material.","PeriodicalId":111726,"journal":{"name":"2018 IEEE International RF and Microwave Conference (RFM)","volume":"55 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131675310","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}

Research works are on-going to find potential material that has the ability to replace the limitation of conventional material. Related to this work, fifth generation (5G) antenna will be completed with high data rate and low interference besides welcoming the advantages of the coming new material in terms of aesthetic value. Since there are some limitations using conventional material for higher frequency, then this paper proposes graphene to be used as radiating or receiving element in antenna design. An antenna with CPW-fed chamfer-shaped with rectangular slot made by graphene at 15 GHz is proposed. The antenna is designed for single and array in which the array has 8 elements with inter-element spacing at 0.71λ.

Some efforts to produce the antenna in compact size are still becoming interesting research topics. In this paper, a complimentary split-ring-resonator (CSRR) incorporated into the radiator of substrate integrated waveguide (SIW) antenna is proposed to acquire the antenna with reduced size. By taking the advantage of CSRR as a small electrically resonator, it is expected the resonant frequency of SIW antenna could be lowered yielding the downsizing of antenna dimension. The proposed antenna which is intended to work at X-band frequency is designed on a 1.6mm thick FR4 epoxy dielectric substrate with the radiator takes an extended half-circle shape. Meanwhile, the CSRR is constructed by 2 concentric rings which are slotted upon the radiator of X-band SIW antenna. The characterization result shows that the realized X-band SIW antenna resonates at the frequency of 10.875GHz with the gain of 1.32dBi which is comparable to the simulation result. In addition, the potency of size reduction by incorporating CSRR into the SIW antenna is also investigated in comparison to the conventional X-band SIW antenna.","PeriodicalId":111726,"journal":{"name":"2018 IEEE International RF and Microwave Conference (RFM)","volume":"5 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121325421","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}

Based on MWC, this paper designs a DC-3 GHz Compressed Sensing (CS) receiver system with commercial devices. Combined with some standard compressed sensing algorithms, this receiver can sense the spectrum from DC to 3 GHz and receive at most six 40 MHz real signals simultaneously without prior knowledge of the carrier frequencies. This receiver with 60 dB dynamic range is designed to have six physical branches, and each branch contains an Analog-to-Digital Conversion (ADC) which operates at 245 MHz. The total sample rate of 1470 MHz is much smaller than the Nyquist sampling rate of 6 GHz.
