Cylindrical Substrate Integrated Waveguide (CSIW) Slot Arrays with Uniform and Nonuniform Spacings Bayraktar, Omer; Aydın Çivi, Hatice Özlem (2014-08-23) Pattern synthesis of a traveling wave longitudinal slot array on the broad wall of cylindrical substrate integrated waveguide (CSIW) is presented at 25 GHz. In order to have low side lobe level (SLL) and high directivity, the Elliot's design procedure for 1 x 25 slotted waveguide array is applied to satisfy the required slot voltage distribution found by aperture projection method for evenly distributed slot array with complex slot voltage distribution. The results are compared with the design which makes u...
Circumferential Traveling Wave Slot Array on Cylindrical Substrate Integrated Waveguide (CSIW) Bayraktar, Omer; Aydın Çivi, Hatice Özlem (Institute of Electrical and Electronics Engineers (IEEE), 2014-07-01) Traveling wave slot array on cylindrical substrate integrated waveguide (CSIW) is designed, fabricated and measured at K-band. CSIW is formed by wrapping the substrate integrated waveguide (SIW) around the cylinder in the circumferential direction. 16 element longitudinal slot array on the broad wall of single CSIW is designed by the Elliot's design procedure. The spacings between the slot elements are determined to reduce the half power beam width (HPBW) and to obtain good matching at 25 GHz. A 4 x 16 slot...
Slots on Cylindrical Substrate Integrated Waveguide Bayraktar, Omer; Aydın Çivi, Hatice Özlem (2012-07-14) Longitudinal slots and coupling between slots placed on the broad wall of a cylindrical substrate integrated waveguide (SIW) are modeled and characterized in order to design a slotted cylindrical SIW array. Characteristics of slot on the SIW bended on a cylindrical surface and effects of radius of curvature to the slot and mutual coupling characteristics are investigated at K band using FEM simulator.
Analysis and design of slotted substrate integrated waveguide antenna on cylindrical surface Bayraktar, Ömer; Aydın Çivi, Hatice Özlem; Department of Electrical and Electronics Engineering (2014) This thesis presents novel traveling wave conformal shunt slot arrays on cylindrical substrate integrated waveguide (CSIW) placed on a cylindrical surface in the circumferential direction at K-band. Mutual couplings of longitudinal slots on broad wall of CSIW are formulated and active admittance formulas of the slots are derived which are used in Elliott’s design procedure to design slotted CSIW arrays. The designs are carried out at 25 GHz using non-uniform and uniform slot separations. The non uniform slo...
Multi-Point Single-Antenna Sensing Enabled by Wireless Nested Split-Ring Resonator Sensors Ozbey, Burak; ERTÜRK, VAKUR BEHÇET; Kurç, Özgür; ALTINTAŞ, AYHAN; DEMİR, Hilmi Volkan (2016-11-01) In this paper, simultaneous multi-point wireless sensing is proposed and demonstrated via multiple sensors in nested split-ring resonator (NSRR) geometry coupled to a single illuminator antenna. In this passive multi-point sensing system, each probe in the sensor array is assigned a non-overlapping spectral interval for frequency shift in response to local mechanical loading around a unique operating resonance frequency in the band of the antenna. Here, it is shown that the antenna is capable of capturing t...
