....Yagi Uda dipole antenna to obtain the balanced input signal for the CPS. The measurement shows higher gain (9.1dB) wider bandwidth (10.3 ) in comparison with a normal microstrip patch antenna. II. Antenna Design Referring to the design curves obtained for the free space Yagi Uda antenna [5], we can obtain reasonably good initial dimension for the length of the director element. To find the optimal length of the director and the separation between the driver and the director, however, we need to use full wave analysis. In this work FDTD simulation is used to calculate the return ....

....types of excitation are considered here. The first will be the delta gap voltage generator and the second will be the coaxial current probe. 4.5. 1 Delta Gap Voltage Generator The delta gap voltage generator is a simplistic source which is commonly used in moment method analysis of wire antennas [131]. Although such sources do not exist in practice, they do give good results for dipole antennas and have been shown to work well with printed transmission lines with electrically small widths. Fig. 4.4 shows the implementation of a delta gap voltage generator where a voltage source is placed ....

....elements. The results of this analysis can be used in designing advanced antenna systems for futuristic Rapidly Deployable Radio Networks (RDRN) 5] Conformal arrays are generally difficult to analyze. The reason is that the Green s function for non planar structures converge very slowly [11] [13]. However, it is still possible to obtain near field information of a non planar array by using very special forms of the appropriate Green s function [11] The formulation of such special Green s functions require substantial development time. Consequently for preliminary analysis, the ....
....in section 2.1. The technique by which the amplitude and phase excitations of elements in a circular array are determined is shown in section 2.2. This technique is simpler and simulates the Digital BeamForming (DBF) technique [7] In this technique the amplitude excitations are determined from [13] and the phases are found following the analysis in [23] Once the complex (amplitude and phase) excitations are known, the patterns can be found from the exact or approximate formulas in [24] 25] These approximate formulas have been shown to work in a variety of practical modeling situations ....
