A new approach is proposed to achieve appropriate amplitude distribution for series-fed linear microstrip patch antenna arrays. Through element coupled patches are further investigated to attain more control on the level of the transmitted signal through the antenna elements. Power coupled to the next element is controlled by adjusting the size of the coupling region (CR) and the width of the gap to accomplish amplitude tapering. An empirical formulation is obtained through parametric analysis which can be employed at different frequencies. The proposed formulation is validated at X, Ku and K-bands. The calculation and the measurement results for an array configuration operating at X-band are given.

Rigorous optimizations of three dimensional antenna arrays using full wave simulations Onol, Can; Gokce, Ozer; Boyacı, Huseyın; Ergül, Özgür Salih (null; 2015-07-09) We present optimizations of three-dimensional antenna arrays using heuristic techniques coupled with the multilevel fast multipole algorithm (MLFMA). Without resorting to any periodicity and infinity assumptions, antenna arrays are modeled with surface integral equations and simulated via MLFMA, which also enables the analysis of arrays with non-identical elements. Genetic algorithms and particle swarm optimization methods are employed on the complex data produced by MLFMA in phasor domain to find optimal s...
Investigation of tightly coupled arrays for wideband applications Arda, Kaan; Dural Ünver, Mevlüde Gülbin; Department of Electrical and Electronics Engineering (2020-10) This thesis aims to provide in depth research on tightly coupled dipole arrays to be used in ultrawideband apertures applications. First, operation principles of tightly coupled dipole arrays are investigated. Starting from the Wheeler’s current sheet aperture concept, some calculations on bandwidth and impedance concepts are conducted. B.A. Munk’s addition to the concept, use of capacitive elements between adjacent dipoles, are introduced. Array unit cell is modeled using equivalent circuit approach,...
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°.
Design and evaluation of V-shaped arrays for 2-D DOA estimation Filik, Tansu; Tuncer, Temel Engin (2008-04-04) A new method for optimum design of V-shaped arrays is presented for azimuth and elevation angle estimation simultaneously. The design criterion is based on the Cramer-Rao Bound (CRB) for joint estimation where the coupling effect between the azimuth and elevation direction of arrival (DOA) angles is taken into account. The design method finds an optimum angle between the linear sub-arrays of the V-array. The computation of the optimum angle is simple due to the monotonic characteristics of the best and wors...
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...
