Ultra wide band is rapidly advancing as a high data rate wireless communication technology. As is the case in conventional wireless communication systems, an antenna also plays a very crucial role in UWB systems. However, there are more challenges in designing a UWB antenna than a narrow band one. A suitable UWB antenna should be capable of operating over an ultra-wide bandwidth as allocated by the FCC. At the same time, satisfactory radiation properties over the entire frequency range are also necessary. This thesis focuses on UWB antenna design and analysis. Studies have been undertaken covering the areas of UWB fundamentals and antenna theory. In recent years, the U-slot patch antenna established itself as a versatile, low profile and cost effective antenna that can be finetuned for ultra-wideband operations. The main objective of this thesis is to propose an effective practical design procedure to design U-Slot antenna and provide physical insight into the design using full wave analysis methods. This research work focuses on developing a novel scheme to design wideband U-Slot antenna. To validate the design technique antenna is fabricated and measured results are compared with the simulated to assess the performance. In this dissertation, effect of reactive loading on probe fed, single layer, U-Slot loaded microstrip antenna is investigated using Theory of Characteristic Modes (TCM). Detailed analysis of reactive loading due to feed location and arm-angle variation is presented. Optimized reactive loading has been shown to produce a modified U-Slot structure without increasing any cost and complexity. The optimized loaded antennas are wideband with a relatively stable radiation pattern. Furthermore, we propose an optimization guideline for a wide band design with stable radiation patterns.

The standard rectangular microstrip patch is a narrowband antenna and provides 6-8 dBi Gain with linear polarization. This example based on the work done in [1],[2], models a broadband patch antenna using a slot in the radiator and develops a dual-band and a tri-band variation from it. In the process, the single wide response has been split into multiple narrow band regions catering to specific bands in the WiMAX standard. These patch antennas have been probe-fed.Building the Single U-Slot Patch
Define Parameters The basic U-slot patch antenna consists of a rectangular patch radiator within which a U-shaped slot has been cut out. As discussed in [1], the patch itself is on an air substrate and thick so as to enable higher bandwidths to be achieved. The presence of the slot structure achieves additional capacitance within the structure which combines with the inductance of the long probe feed to create a double resonance within the band. The geometry parameters based on [2] are defined and shown in a drawing below.
Define radiator shape - Single U-slot
Use the rectangle shape primitives in Antenna Toolbox™ to create the U-slot patch radiator shape. Boolean subtraction operation is used among the shape primitives for this purpose.
Define ground shape
Create the ground plane shape for the antenna. The groundplane in this case is rectangular and 71 mm x 52 mm in size.
Define stack Hoosier park casino anderson indiana.
Use the pcbStack to define the metal and dielectric layers and the feed for the single U-slot patch antenna. The layers are defined top-down. In this case, the top-most layer is a metal layer defined by the U-slot patch shape. The second layer is a dielectric material, air in this case, and the third layer is the metal ground plane.Calculate and Plot Reflection Coefficient
Mesh the structure by using a maximum edge length which is one-tenth the wavelength at the highest frequency of operation which is 6 GHz for this example. Compute and plot the reflection coefficient for this antenna over the band. The reflection coefficient is plotted with a reference impedance of 50 ohms.Calculate and plot pattern
Plot the radiation pattern for this antenna at the frequencies of best match in the band.Dual-band U-Slot Patch Antenna
Define Parameters Wind creek casino in wetumpka alabama phone number.
To achieve dual-band behavior as shown in [1], [2], the double resonance is modified such that the two contributing resonances, i.e. from the patch and from the slot do not merge. To do so the existing slot parameters are adjusted and a second slot is introduced into the structure. The parameters for the double U-slot are listed below as per [2] and a figure annotated with the variables used is shown.
