Conference Object Design and Fabrication of Dual-Frequency H-Shaped Antenna;(IEEE, 2013) Dagdeviren,B.; Yavuz Kapusuz,K.; Can,S.; Aydin,E.; Kapusuz, K. YavuzIn this study, the parameters that effects the operating frequency of dual frequency H-shaped antenna are examined. These parameters are determined as type of the dielectric constant of substrate, substrate thickness, dimensions of the antenna and dimensions of the slots that are used to obtain shape of H. The produced and simulated results of the proposed antennas are presented and compared with the studies in literature. © 2013 IEEE.Conference Object Reader Antenna Design for Rfid Applications;(IEEE, 2013) Kaynakö,G.; Kzlu,N.; Kapusuz,K.Y.; Can,S.; Aydzn,E.; Kaynakoz, Goktug; Kilic, N. Koray; Aydin, ElifIn this paper, a coplanar waveguide (CPW) fed microstrip patch antenna is designed on finite element method based simulation program and fabricated in order to use reader antenna in Radio Frequency Identification (RFID). The results of the simulations and the produced antennas are presented in the study. The produced microstrip patch anten na has a 105MHz bandwidth and operates in between 895-1000 MHz . © 2013 IEEE.Conference Object Citation - Scopus: 3Dual-Frequency, Two Shorting Pin-Loaded Equilateral Triangular Patch Antennas(Electromagnetics ACAD, 2012) Can,S.; Kapusuz,K.Y.; Aydin,E.This study presents the resonant frequencies of several antennas, which are dual-frequency antennas. These antennas possess two shorting pins to form dual frequency. Among several methods to provide dual operation, two shorting pins are used to form dual frequency equilateral triangular antennas since there are limited studies on this issue and higher frequency ratios are achievable. The present study has been done with this in mind in order to contribute to related literature on such antennas. Here, the parameters that affect the resonant frequencies of the antenna are also evaluated. The thickness, side length, and shorting pin positions are changed numerous times, and the resonant frequencies are examined according to the change of these parameters. Finally, the frequency ratios are determined for each variation, and the results are compared. The proposed antennas in present study achieved a frequency ratio around 5.7, which is significantly higher from the ones presented in the literature.
