We present a new type of pixel antennas involving hexagonal unit cells that are suitable for fabrication in low-cost inkjet-printing setups. Antennas are optimized in a rigorous simulation environment based on the multilevel fast multipole algorithm integrated into genetic algorithms. Hexagonal cells are suitable for both the optimization environment and fabrication setup. Optimizations are performed particularly to design radio-frequency-identification tags, by removing pixels from a given template to achieve the best performance, e.g., minimum reflection coefficient values and maximum reading ranges. The overall design, optimization, and fabrication procedure has a fast demand response, requiring only one day from a request to the prototype stage.

Hexagonal- Pixel Surfaces for the Reconfiguration of Inkjet-Printed Antennas Guler, Sadri; Ceylan, Hasan Akin; Ergül, Özgür Salih (2018-11-02) We present a new method for the reconfiguration of inkjet-printed antennas to make them operate at different frequencies while matching to different impedances other than originally designed. Suitable antennas are modified by replacing conventional ground planes with patterned structures involving optimal arrangements of hexagonal cells. The cells are switched on or off, while the optimal distributions are found via genetic algorithms to reach desired characteristics. A full-wave solver is used for the requ...
Three Dimensional Microfabricated Broadband Patch and Multifunction Reconfigurable Antennae for 60 GHz Applications Hunerli, H. V.; Mopidevi, H.; Cagatay, E.; Imbert, M.; Romeu, J.; Jofre, L.; Cetiner, B. A.; BIYIKLI, NECMİ (2015-05-17) 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 a broadband patch antenna along with the design and microfabrication of multifunction reconfigurable antenna (MRA) in its static form excluding active switching. The first design is a patch antenna where the energy is coupled with a conductor-backed (CB) coplanar waveguide (CPW)-fed loop s...
Beam Steerable Traveling Wave Meander Line Antenna Using Varactor Diode for X-Band Applications Gokalp, Nihan; Aydın Çivi, Hatice Özlem (2008-07-11) This paper presents a novel beam steerable meander line antenna with varactor diode for X-band applications. Beam steering has been achieved by loading the arms of the meander line antenna with varactor diodes. The capacitances of the varactor diodes have been controlled by DC bias voltage. Instead of varactor diodes, RF-MEMS variable capacitances can be used to scan the beam. Since the insertion loss of MEMS capacitances are small compared to loss of varactor diodes, use of MEMS capacitors will increase th...
Wideband omnidirectional and sector coverage antenna arrays for base stations Alatan, Lale (2018-01-01) By using parallel strip line fed printed dipole antennas as array elements, an omnidirectional antenna array and a wide angle sector coverage array operating in octave band are designed. A maximum deviation of ±1.25 dB from the omnidirectional pattern is achieved for the omnidirectional array, and the average gain of the antenna was measured as being 5 dB in the 1.35–2.7GHz band. For the sector coverage array, a special reflector design is utilized to maintain a half power beam width of around 115◦ with a s...
Design, Simulation, and Fabrication of Broadband Inkjet-Printed Log-Periodic Antennas Dolapci, Turker; Mutlu, Feza; Ergül, Özgür Salih (2017-09-27) We present design and computational analysis of log-periodic antennas that are fabricated by using low-cost inkjet printing technology. The designed antennas operate in the 1.5-2.5 GHz range and are suitable for diverse applications, including energy harvesting at WiFi and GSM bands. Suitable designs are fabricated by using silver-based inks in standard commercial printers. Despite the challenges in both design and fabrication processes, we demonstrate log-periodic antennas with desired operating properties...
