This thesis includes the design, production and measurement of a reactively loaded microstrip patch antenna. The dual band and circular polarization operation are achieved through the use of narrow slots etched close to the radiating edges on a nearly square patch. During the design process, the effects of antenna parameters on the input impedance and axial ratio characteristics are investigated. A step-by-step procedure is followed during the design process. First, the dual band characteristic is investigated on a slot loaded rectangular patch. Then, an attention is given to improve the circular polarization. Finally, the desired structure is analyzed and information about the design parameters is obtained by means of parametric study. These parametric analyses are done in full wave electromagnetic solver tool HFSS. The designed dual band circularly polarized microstrip patch antenna is manufactured and measured. Acceptable agreement between simulation and measurement results is obtained.

Analysis of dual - polarized aperture - coupled microstrip antennas with H-shaped slots and equivalent circuit modeling of H shaped slots
İşeri, Kadir; Alatan, Lale; Department of Electrical and Electronics Engineering (2012)
This thesis includes the design, production and measurement of a wideband dualpolarized X-band aperture-coupled microstrip patch antenna. The wideband and dual-polarized operation is achieved through the use of H-shaped coupling slots. Therefore, the equivalent circuit modeling of a microstrip line fed H-shaped slot is also studied in this thesis. A step-by-step procedure is followed during the design process of the dual-polarized aperture-coupled microstrip antenna. First, an aperture-coupled microstrip an...
Analysis and design of active annular ring coupled circular patch antenna
Gebeşoğlu, Durmuş; Koç, Seyit Sencer; Department of Electrical and Electronics Engineering (2017)
This thesis includes the design, production and measurement of the active, dual band annular ring coupled circular patch antenna. The dual band operation is achieved by using stacked patches. 3 dB hybrid is used to obtain circular polarization. Effects of antenna parameters on the input impedance and frequency ratio between the resonance frequencies are observed. Design has been achieved step by step. Firstly, dual band operation is investigated by using stacked patches. An annular ring antenna and a circul...
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...
Design of pattern reconfigurable antenna employing RF-MEMS switches
Gök, Çağlar; Alatan, Lale; Department of Electrical and Electronics Engineering (2022-8-17)
In this thesis, the design, simulations, fabrication and measurements of reconfigurable antennas for use in 5G Massive MIMO systems are presented. 26 GHz is chosen as the operating frequency and RF-MEMS switches are used as control elements for pattern reconfiguration. As a first step, a patch antenna is designed based on the excitation of different operation modes of different resonators. A circular patch in the center and a ring resonator structure around it are used to create different radiation patterns...
Development of multiband microstrip antennas for GPS applications
Önder, Mustafa Caner; Aydın Çivi, Hatice Özlem; Department of Electrical and Electronics Engineering (2019)
In this thesis study, the design, fabrication and measurements of dualband and triband circularly polarized microstrip antennas for GPS applications are presented. Characteristic mode analysis technique is applied to get an insight into circularly polarized patch antennas. A design flow is presented for a circularly polarized L1 GPS band microstrip antenna by using characteristic mode analysis. A single fed L1/L2 GPS band right hand circularly polarized four-slotted patch antenna is designed by using reacti...
