When antenna arrays are placed on platforms, antenna patterns and antenna characteristics change significantly. Calibration of antenna arrays becomes an inevitable and important task to correct the imperfections due to the antenna surroundings. In this paper, a time-gating method is proposed to calibrate the direction finding antenna array on a UH-60 helicopter on ground. The helicopter is placed above the ground plane whereas the source antenna is further away to account for the reflections from the helicopter appropriately. It is shown that the proposed approach can be used effectively to eliminate the ground reflections and obtain accurate calibration data. This technique is both effective and a cost cutting approach for array calibration.

Modified neural multiple source tracking algorithm in the presence of mutual coupling
Caylar, Selcuk; Leblebicioğlu, Mehmet Kemal; Dural, Guelbin (2007-06-15)
In smart antenna systems, mutual coupling between elements can significantly degrade the processing algorithms [1]. In this paper mutual coupling effects on Modified Neural Multiple Source Tracking Algorithm (MN-MUST) has been studied. MN-MUST algorithm applied to the Uniform Circular Array (UCA) geometry for the first time. The validity of MN-MUST algorithm in the presence of mutual coupling has been proved for both Uniform Linear Array (ULA) and UCA. Simulation results of MN-MUST algorithm are provided fo...
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...
Circular arrays of log-periodic antennas for broadband applications
Ergül, Özgür Salih (2006-11-10)
Circular arrays of log-periodic (LP) antennas are designed for broadband applications. A sophisticated electromagnetic simulation environment involving integral equations and fast solvers is developed to analyze the LP arrays both accurately and efficienuy. The resulting matrix equation obtained by the discretization of the electric field integral equation is solved iteratively via the multilevel fast multipole algorithm (MLFMA). Genetic algorithms interacting with MLFMA is employed to optimize the excitati...
Reconfigurable Reflectarrays: Design, Analysis and Fabrication
Aydın Çivi, Hatice Özlem (2015-05-17)
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...
