This paper presents an elliptically polarized axial-mode helical antenna for UHF fuze radar applications with a conformal polarizer. The designed monofilar axial-mode helical antenna is circularly polarized. However, the circularly polarized antennas have polarization mismatch problem in above ground applications like fuze or altimeter radar. Therefore, antennas used in these applications should better be designed as linearly or elliptically polarized in order to obtain moderate received power levels. In this paper, the axial ratio of the designed antenna is increased to 7.6 dB from 1.35 dB at 850 MHz by use of a conformal polarizer. This antenna is measured in an anechoic chamber.

A Two-Stage Digital-to-Analog Converter for Bias Correction in Uncooled Microbolometer Arrays Toprak, Alperen; Tepegoz, Murat; Akın, Tayfun (2011-04-29) This paper introduces a detector biasing scheme proper for resistive microbolometer type uncooled thermal detector focal plane arrays (FPAs). The proposed scheme utilizes a 2-stage digital-to-analog converter (DAC) architecture where the first DAC stage generates the voltage interval that covers the bias voltage range of the overall FPA, while the second stage generates the high resolution analog voltages that are used to apply pixel-specific bias voltages. The second DAC stage output includes a resistive l...
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...
A Miniature Low-Cost LWIR Camera with a 160x120 Microbolometer FPA Tepegoz, Murat; Kucukkomurler, Alper; Tankut, Firat; Eminoglu, Selim; Akın, Tayfun (2014-05-08) This paper presents the development of a miniature LWIR thermal camera, MSE070D, which targets value performance infrared imaging applications, where a 160x120 CMOS-based microbolometer FPA is utilized. MSE070D features a universal USB interface that can communicate with computers and some particular mobile devices in the market. In addition, it offers high flexibility and mobility with the help of its USB powered nature, eliminating the need for any external power source, thanks to its low-power requiremen...
A CMOS n-well microbolometer FPA with temperature coefficient enhancement circuitry Eminoglu, S; Tezcan, DS; Akın, Tayfun (2001-04-20) This paper reports the development of a low-cost CMOS microbolometer focal plane array with a new temperature coefficient enhancement readout circuit. We have recently reported an uncooled microbolometer detector that uses the CMOS n-well layer as the active material, where the suspended and thermally isolated n-well structure is obtained by silicon bulk micromachining of fabricated CMOS dies. In addition, we have successfully fabricated a 16x16 n-well microbolometer FPA. Although n-well is single crystal 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...
