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.

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...
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...
Reconfigurable CPW-FED dual-frequency rectangular slot antenna using RF MEMS technology Erdil, Emre; Topalli, Kagan; Aydın Çivi, Hatice Özlem; Akın, Tayfun (2005-07-08) A reconfigurable dual-frequency rectangular slot antenna using MEMS technology is presented. In this structure, a rectangular slot antenna is integrated with MEMS cantilever type capacitors. Simulation results show that the structure has a dual frequency behavior where both of the resonant frequencies can be reconfigured dynamically. By the actuation of MEMS cantilevers, the lower resonant frequency shifts 1.2 GHz, whereas the higher resonant frequency has a shift of 330 MHz without any distortion of the ra...
Analysis of a calibration method for airborne receive-only phased array antennas with self-alignment Elik, Furkan Bahadır; Demir, Şimşek; Department of Electrical and Electronics Engineering (2022-9-15) The calibration of the phased array antennas plays crucial role to ensure the performance of the beam steering capability. Most of the guided missiles utilize phased arrays, thus, the calibration routines should be optimized. Since guided missiles are spatially limited, calibration hardware should not introduce new geometry to the antenna. This limits possible calibration methods of the antennas on the missiles. This study develops a calibration method for semi-active guided missiles and analyzes this metho...
Analysis and design of cylindrically conformal microstrip antennas Taşoğlu, Ali Özgür; Dural Ünver, Mevlüde Gülbin; Department of Electrical and Electronics Engineering (2011) Cylindrically conformal microstrip antennas are investigated. Two different structures, namely proximity coupled and E-shaped microstrip antennas are analyzed and information about the design parameters is obtained by means of parametric study. With these structures, cylindrical arrays, having omnidirectional radiation in the circumferential plane of the cylinder, are designed. Proximity coupled cylindrical arrays operate in the 2.3-2.4 GHz aeronautical telemetry band with approximately 4% bandwidth. On the...
