Abstractó In this paper, a
transmission line model is used to design log periodic of bow-tie antennas
arrays operating in C band fed in series with enhanced bandwidth. The transmission
line model is simple, precise and allowing taking into account the whole
geometrical, electric and technological characteristics of the antennas arrays.
To validate this last, the obtained simulation results are compared with those
obtained by the momentís method (MoM) of the Momentum software. Using this
transmission line approach the resonant frequency, input impedance, return loss
can be determined simultaneously. Agreements between transmission line model
data and the momentís methods results were achieved.
Key words : Microstrip bowtie
