Investigations on frequency beam scanning microstrip (bsms) antenna structures

Dündar, Burhan
Beam scanning Microstrip (BSMS) antenna is designed to work at center frequency of 10 GHz for using in the scanning applications of 9 GHz to 11 GHz band. The design parameters are defined and by using an Electromagnetic Simulation software program, the parameters are optimized. A Beam Scanning Microstrip Antenna is produced as a prototype and the measurement’s results are compared with theoretical results. In conclusion, the values of deviation between theoretical and experimental results are discussed.


Design, analysis, and implementation of circular disk - annular ring (cdar) antenna
Kırık, Mustafa Sancay; Koç, Seyit Sencer; Department of Electrical and Electronics Engineering (2007)
In satellite applications, a circularly polarized satellite antenna is desirable with a pattern that results in constant received power while the distance between the transmitter and the receiver is changing. The Circular Disk - Annular Ring (CDAR) antenna satisfies these requirements along with other requirements for the satellite antenna. The CDAR antenna is a combination of a Circular Disk and an Annular Ring patch antennas. In this thesis, a circularly polarized CDAR antenna that is fed from a single po...
Interference suppression by using space-time adaptive processing for airborne radar
Eryiğit, Özgür; Yılmaz, Ali Özgür; Department of Electrical and Electronics Engineering (2008)
Space-Time Adaptive Processing (STAP) is an effective method in Ground Moving Target Indicator (GMTI) operation of airborne radars. Clutter suppression is the key to successful MTI operation. Airborne radars are different than the ground based ones in regard to clutter due to the displacement of the platform during operation. When STAP methods are to be investigated, one needs to have accurate signal models while evaluating performance. In this thesis, a comprehensive received signal model is developed firs...
An investigation on plasma antennas
Tiğrek, Recep Fırat; Hızal, Altunkan; Department of Electrical and Electronics Engineering (2005)
The plasma antennas offer a new solution to new requirements that are imposed on antenna systems with the advancing communication technology and increasing demand on wider frequency bands. In this thesis the plasma antennas are investigated for the radar and communication applications. The interaction of gas and semiconductor plasma with electromagnetic waves is inspected theoretically, and several experiments on the interaction of microwaves with gas plasma are conducted. Results of these experiments show ...
Multiuser receivers for cdma downlink
Duran, Ömer Agah; Candan, Çağatay; Department of Electrical and Electronics Engineering (2008)
In this thesis, multiuser receivers for code division multiple-access (CDMA) downlink are studied under frequency selective fading channel conditions. The receivers investigated in this thesis attempt to estimate desired symbol as a linear combination of chip-rate sampled received signal sequence. A common matrix-vector representation of signals, which is similar to the model given by Paulraj et. al. is constructed in order to analyze the receivers studied in this thesis. Two receivers already well known in...
Waveform design for pulse doppler radar
Ağırman, Handan; Severcan, Mete; Department of Electrical and Electronics Engineering (2005)
This study is committed to the investigation of optimum waveforms for a pulse doppler radar which uses a non linear high power amplifier in the transmitter. The optimum waveform is defined as the waveform with the lowest peak and integrated side lobe level, the narrowest main lobe in its autocorrelation and the narrowest bandwidth in its spectrum. The Pulse Compression method is used in radar systems since it is more advantageous in terms of the resolution. Among all pulse compression methods, the main focu...
