This thesis includes the design, simulation, production and measurement of a differential fed magneto-electric dipole antenna with cavity operating at ultrawideband (3.3 GHz – 10 GHz). This antenna consists of a differential feeding structure, an electric dipole, a magnetic dipole and a cavity. The ultra-wideband operation is achieved through the use of differential feeding structure and cavity. A step-by-step procedure is followed during the design process of the differential fed magneto-electric dipole antenna with cavity. First, a gamma-shaped strip fed magneto-electric dipole antenna is designed to study the effects of the antenna parameters on the return loss and the characteristics of the antenna gain. These parametric analyses are done in Ansys HFSS, a high frequency electromagnetic field simulation program. By the help of the experience gained through these parametric analyses, a differential fed magneto-electric dipole antenna is designed and simulated. Then, in order to achieve design requirements a cavity is incorporated into the design. vi Finally, the designed differential fed magneto-electric dipole antenna with cavity is manufactured, measured, and its performance is compared with simulation results.

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...
Theoretical investigation and design of wideband dielectric resonator antennas
Yüksel, Yılmaz Çağrı; Alatan, Lale; Department of Electrical and Electronics Engineering (2015)
The aim of this thesis is to utilize Dielectric Resonator Antennas (DRA) as array elements due to their advantages over other conventional antenna elements such as dipoles and microstrip patches. Depending on both the excitation mechanisms and the antenna shape, a Dielectric Resonator Antenna (DRA) provides its designer multiple independent degrees of freedom. In this thesis three antenna shapes, namely hemispherical, cylindrical and rectangular DRAs, are investigated. The cylindrical and the rectangular sh...
Design of Irregularly Shaped Patch Antennas by using the Multiport Network Model
Sener, Goker; Alatan, Lale; Kuzuoğlu, Mustafa (2008-07-11)
The multiport network model (MNM) is an analytical method that is used to analyze microstrip antennas. MNM is based on defining ports along the periphery of the patch and evaluating the impedance matrix corresponding to these ports by using the Greenpsilas function for the cavity under the patch. For regular rectangular, triangular and circular patches, analytical expressions for the Greenpsilas function are available. In the analysis of irregular patches, Greenpsilas functions cannot be calculated explicit...

In this paper, design, simulation, production and measurement of a coplanar broad-band microstrip antenna printed on an alumina ceramic substrate is presented. Antenna may be used as an element in a radar applications operating at X-band (8 GHz-12 GHz). The antenna driven system consists of one more directors because of the requirements of directivity. The reason of using high dielectric substrates the antenna can be printed on very small spaces. Antenna in Package structure's temperatures rising up rapidly...
