    Dipole Antenna Designs For UHF RFID Passive Tag
    (IEEE, 2014) Keskin, Nesem; Imeci, Taha; Rahman, Shah M. T.; Karacuha, Ertugrul
    Use of REID systems have become popular in many areas such as service, purchase and distribution logistics, manufacturing and material flow to provide information about people, animals and products. Hence, to improve the efficiency of these systems, the amount of research work in this field is increasing. In addition to these works, a considerable amount of research has also been conducted to spread the signal to wideband in order to improve the data transfer consuming less power instead of sending the signal in narrow band with more power. Furthermore, energy consumption can be reduced by using wideband technology. In this study, the goal is to design an antenna that operates in the range 800-1400MHz UHF RFID frequencies with wideband. To design the dipole antenna that can be operated across wide frequency bands, a patch antenna is used. These passive dipole antennas are designed for REID tags. The EPC Gen2 (EPCglobal UHF Class 1 Generation 2) standard is supported in ISO/IEC 18000 for REID.

    H-Shape of a trapezoidal neck High-Gain Patch Antenna
    (IEEE, 2017) Yerinde, O. Faruk; Moussa, O. A.; Celik, Arif; Topalomer, Mehmet; Imeci, Taha
    In this study, a microstrip antenna simulated between 1-11 GHz is manufactured and presented results with measurements. Then simulation results are presented.|S11| simulation and measurement results almost show perfect agreement. S11, the input reflection coefficient parameter has the value of -31.24 dB at the center frequency and the resonance frequency has the gain value of 11.21 dBi at 8.24 Ghz. Especially, the antenna has been exclusive with Slits and trapezoid centre piece.

    Microstrip Dual-Bandpass Filter Design
    (IEEE, 2017) Eren, Bora; Akyuz, Burhan; Dikkafa, Mustafa; Alaca, Ozgur; Imeci, Taha; Gungor, Oguzhan Salih
    Dual-bandpass microstrip filter design is suggested for small-scale device. Design of dual-bandpass microstrip filter has been created with concentric square structure by using microstrip resonator. Both of resonators have been used to get dual-bandpass frequencies and fed with only one source. Proposed design has been created and simulated on Sonnet software and also prototype has been builted and tested. According to result of simulation, value of S11 is -29.79 dB and value of S12 is 0.04797 dB about 4.6 GHz, as for about 12.65 GHz, value of S11 is -22.67 dB and value of S12 is -0.09642 dB.

    A Symmetric U-Slot Microstrip Patch Antenna Design
    (IEEE, 2015) Boyaci, Ali; Imeci, Taha
    In this paper a U-shaped slotted microstrip patch antenna that aims to work in 8.86-8.98GHz frequencies was designed and simulated. First antenna design was in shape of U-slot, then it was changed into [] shaped slot. Sonnet Suites version 13.56 was used as simulation program [ 1]. Air thickness is 20mm and the distance between ground ant the patch is 5mm. S11 is nearly -11.20dB. Antenna has 7.55dB gain at resonance frequency.
