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 slot, resulting in a broad bandwidth. The feed circuitry along with the loop is formed on a quartz substrate (at 60 GHz), on top of which an SU-8-based three-dimensional (3D) structure with air cavities is microfabricated. The patch metallization is deposited on top of this structure. The second design is a CB CPW-fed loop slot coupled patch antenna with a parasitic layer on top. The feed circuitry along with the loop is formed on a quartz substrate. On top, the patch metallization is patterned on another quartz substrate. The parasitic pixels are deposited on top of these two quartz layers on top of an SU-8 based 3D structure with air cavities.

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...
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...
Design of pattern reconfigurable antenna employing RF-MEMS switches Gök, Çağlar; Alatan, Lale; Department of Electrical and Electronics Engineering (2022-8-17) In this thesis, the design, simulations, fabrication and measurements of reconfigurable antennas for use in 5G Massive MIMO systems are presented. 26 GHz is chosen as the operating frequency and RF-MEMS switches are used as control elements for pattern reconfiguration. As a first step, a patch antenna is designed based on the excitation of different operation modes of different resonators. A circular patch in the center and a ring resonator structure around it are used to create different radiation patterns...
Design and analysis of ultra-wideband (UWB) printed monopole antennas of circular shape Karadağ, Serkan; Aydın Çivi, Hatice Özlem; Department of Electrical and Electronics Engineering (2017) This study proposes three microstrip line fed circular monopole antennas with ultra-wideband (UWB) characteristics, improved omnidirectional radiation pattern and WLAN (5 GHz-6 GHz) band notched characteristics for wireless and mobile communication systems. In this thesis, first, a microstrip line fed ultra-wideband ring monopole antenna with improved omnidirectional radiation pattern is designed, fabricated and measured. Two corners are tapered on the ground plane for increasing impedance bandwidth. In ord...
Reconfigurable Reflectarrays: Design, Analysis and Fabrication Aydın Çivi, Hatice Özlem (2015-05-17) Reflectarray antennas combine the advantages of both reflector and phased array antennas. Therefore, they offer low-loss, low-cost solutions for the high gain, beam steering and beam shaping applications. First the current progress and future perspectives regarding the design and analysis of reflectarrays are discussed. Then, recent technological developments and techniques that are used to realize reconfigurability in reflectarrays are presented.
