This paper presents millimeter wave phased array antenna for short range communication applications at 35 GHz. The antenna array is formed by 1 x 16 microstrip antipodal tapered slot antennas each connected to RF MEMS phase shifters for beam steering. The simulation and measurement results of the single antenna element are presented and the phase shifter structure to be used in the array is described in the paper. RF MEMS phase shifters are fabricated using an in-house surface micromachining process.

35 GHz phased array antenna using DMTL phase shifters Guclu, Caner; Cetintepe, Cagri; Aydın Çivi, Hatice Özlem; Demir, Şimşek; Akın, Tayfun (2010-08-27) This paper presents the design of a monolithic phased array antenna with DMTL phase shifters on quartz substrate operating at 35 GHz. The design integrates DMTL phase shifters, rectangular slot antennas with the feed network comprising CPW lines, CPW T-junction and corners. On the four branches of the antenna, there are 5-bit phase shifters using 31 MEMS bridges, covering 360° with a resolution of 11.25°.
Waveguide-based Monopulse Wideband Travelling-Wave Array GULTEPE, Gokhan; DOGAN, Doganay; Aydın Çivi, Hatice Özlem (2017-07-14) A novel, travelling-wave, waveguide antenna structure with monopulse capability in the two principal planes is proposed with increased frequency bandwidth. The array consists of two interleaved waveguide arrays which provide appropriate excitations to the antenna elements above the waveguide to generate proper sum and difference patterns. With the use of printed antennas and the elimination of the narrow frequency characteristics of the slots on the waveguides, the bandwidth of the array is greatly improved.
Phased array antenna calibration and experimental validation Yalım, Alper; Demir, Şimşek; Department of Electrical and Electronics Engineering (2013) In this thesis, nine different methods aiming calibration of Phased Array Antenna (PAA) and Multifunctional Radars which employ PAA are presented. Those calibration methods are described, procedures of the methods are explained in detail, and information about constraints and measurement restrictions of those methods is given. As one step further, comprehensive work is focused on Multi-Element Phase Toggling (MEP) method and Rotating Element Vector (REV) method. Results of simulations are shown, theoretical...
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...
Dynamic analysis of CMUTs in different regimes of operation Bayram, Barış; Ergun, AS; Yaralioglu, GG; Khuri-Yakub, BT (2003-01-01) This paper reports on dynamic analysis of an immersed single capacitive micromachined ultrasonic transducer (CMUT) cell transmitting. A water loaded 24 mum circular silicon membrane of a transducer was modeled. The calculated collapse and snapback voltages were 80 V and 50 V, respectively. The resonance frequency, output pressure and nonlinearity of the CMUT in three regimes of operation were determined. These regimes were: a) the conventional regime in which the membrane does not make contact with the subs...
