An 8 x 4 substrate integrated waveguide (SIW) slotted SIW array is designed at 25 GHz to achieve -20 dB side lobe level (SLL). The slotted SIW array is designed monolithically integrated with a novel 1 x 8 power divider which provides -20 dB SLL Taylor distribution weights with uniform phase distribution. The desired SLL is obtained in simulated radiation pattern.

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...
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°.
Slot Array on Curved Substrate Integrated Waveguide Bayraktar, Omer; Aydın Çivi, Hatice Özlem (2013-07-13) Longitudinal slot array on broad wall of substrate integrated waveguide (SIW) placed on cylindrical surface is designed at 25 GHz for conformal array applications where the SIW lies in the circumferential direction of cylinder.
Sparse recursive filtering for O 1 stereo matching Gürbüz, Yeti Ziya; Alatan, Abdullah Aydın (2015-09-30) Recursive edge-aware filters have been proved to be one of the most efficient approaches for cost aggregation in stereo matching. However, disparity search space dependency, as a result of full search, is the bottle-neck of these local techniques that prevent further reduction in computation. In this paper, the cost aggregation and correspondence search problems are re-formulated to enable adaptive search for each pixel during recursive operations that provides significant reduction in computational complex...
