    • Accurate resonant frequency computation of multisegment rectangular dielectric resonator antennas 

      Gürel, Ç. S.; Coşar, H.; Akalin, Ö. (Taylor & Francis, 2010)
      In this study, multi-segment dielectric resonator antenna (MSDRA) is analyzed. A new formulation depending on the Weighted Average Model (WAM) is proposed for the determination of resonant frequency which is called as ...
    • Development of micro-structured metamaterials for innovative antenna layouts 

      Bilotti F.; Capolino F.; Gonzalo, R.; Özbay, Ekmel; Romeu J.; Schuchinsky, A.; Tretyakov, S.; Vardaxoglou, Y. (IEEE, 2007)
      In this paper, we present the joint activities developed in the frame of the FP6 European Network of Excellence METAMORPHOSE in the field of new micro-structured materials for antenna applications. One of the key scientific ...
    • Microwave transmission through metamaterials in free space 

      Aydin, K.; Bayindir, M.; Ozbay, E. (2002)
      To investigate properties of metamaterials, composite structures which consists of periodical arrangement of thin copper wires and SRRs on a circuit board was constructed. Through this, the transmission properties of ...
    • A Miniaturized Patch Antenna by Using a CSRR Loading Plane 

      Ramzan, M.; Topalli, K. (Hindawi Publishing Corporation, 2015)
      This paper presents a design methodology for the implementation of a miniaturized square patch antenna and its circuit model for 5.15 GHz ISM band. The miniaturization is achieved by employing concentric complementary split ...
    • Photonic band gap effect and localization in two-dimensional Penrose lattice 

      Bayindir, M.; Cubukcu, E.; Bulu I.; Ozbay, E. (2001)
      A study of photonic bandgap effect and localization in two-dimensional Penrose lattice was performed. Penrose quasicrystals consisted of dielectric rods and defect characteristics of various inequivalent sites of the crystal ...
    • Photonic band gap structures for WDM applications 

      Bayindir, M.; Akarca, S.S.; Ozbay, E. (2002)
      A new structure by combining a single cavity and coupled-cavity waveguides (CCWs) for wavelength division multiplexing (WDM) applications was proposed. As such, a structure in which the coupling between the cavity mode and ...
    • Three dimensional microfabricated broadband patch and multifunction reconfigurable antennae for 60 GHz applications 

      Hünerli H. V.; Mopidevi, H.; Cağatay, E.; Imbert, M.; Romeu, J.; Jofre, L.; Çetiner, B. A.; Bıyıklı, Necmi (IEEE, 2015-04)
      In this paper we present two antenna designs capable of covering the IEEE 802.11ad (WiGig) frequency band (57-66 GHz and 59-66 GHz respectively). The work below reports the design, microfabrication and characterization of ...
