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.

Design of asymmetric coplanar strip folded dipole antennas /
Karaciğer, Kamil; Alatan, Lale; Department of Electrical and Electronics Engineering (2014)
This thesis includes the design, simulation, production and measurement of an asymmetric coplanar strip folded dipole antenna suitable to be used as an element in a linear array operating at S-band (2.7 GHz - 3.3 GHz). In this same manner, its usefulness as an array antenna is also explored in this thesis. This antenna element consists of a microstrip line feed, microstrip to coplanar stripline transition (BALUN) and asymmetric coplanar strip (ACPS) folded dipole. The planar folded dipole can be constructed...
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...
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.
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...
Design and Implementation of Transmitting and Receiving Antenna Pair on Flat Ring Surface
Haykir, Yigit; Karadağ, Savaş; Dagdeviren, Birkan; Demir, Şimşek (2018-11-02)
In this work, design and implementation of broadside altimeter antenna on circular ring surface are performed. Utilizing array factor formulation, possible locations for circular array elements are chosen. Slitted microstrip patch antennas are used for an efficient design. Satisfactory results are obtained for an altimeter antenna that can be utilized in missile, aircraft or spacecraft applications.
