A Novel Input Impedance Computation Method for Coaxial Probe Fed Microstrip Antennas by Utilizing Characteristic Modes
Cetin, Metehan; Alatan, Lale (2017-07-14)
A method to efficiently compute the input impedance of the coaxial probe fed microstrip antennas by using characteristic modes is proposed in this paper. The efficiency is achieved by defining a discontinuous source curren...
Performance Comparison of Different Sparse Array Configurations for Ultra-Wideband, Near-field Imaging Applications
Cetin, Beyzat Talat; Alatan, Lale (2017-03-24)
The aim of this study is to compare the performance of different multiple-input multiple-output (MIMO) array topologies, intended to be used in ultra-wideband (UWB) near-field imaging applications, by using an analysis met...
Interference Supression in GPS Receivers using Spatial Filtering
Erdem, Fatih; Dabak, Omer Can; Sonmez, Tolga; Alatan, Lale; Koç, Seyit Sencer (2016-05-19)
GPS receiver operation can be interrupted by intentional/unintentional jammers even with low power levels. As the jammers become more abundant, protection of critical systems gains importance. In this work, it is aimed to ...
Dual Band PIFA Design For Biomedical Applications

Accuracy and efficiency improvements in iterative hybridization of the method of moments MoM and physical optics PO
AKBAS, MUSTAFA; Alatan, Lale; Ergül, Özgür Salih (2016-04-15)
Full-wave electromagnetic solutions of electrically large objects require large amounts of computer storage and CPU power. Therefore, full-wave techniques, such as the method of moments (MoM), are frequently hybridized wit...
Interference Suppression in a GPS Receiver with 4 Element Array Design and Implementation of Beamforming Algorithms
Dabak, Omer Can; Erdem, Fatih; Sonmez, Tolga; Alatan, Lale; Koç, Seyit Sencer (2016-04-14)
Global Positioning System (GPS) jammers add excessive noise to the received low power GPS signals and have capability to either weaken or completely destroy the positioning performance of GPS receivers for both civilian an...
A Novel Approach for the Efficient Computation of 1-D and 2-D Summations
Karabulut, E. Pinar; ERTÜRK, VAKUR BEHÇET; Alatan, Lale; Karan, S.; Alisan, Burak; Aksun, M. I. (2016-03-01)
A novel computational method is proposed to evaluate 1-D and 2-D summations and integrals which are relatively difficult to compute numerically. The method is based on applying a subspace algorithm to the samples of partia...
