Abstract
The C shaped structures and alike have been widely used in numerous antenna
designs for various applications. In this paper, a printed slot antenna has been introduced as
a candidate for use in the dual band wireless communication applications. The antenna slot
structure is to be composed of two or more C shaped slots with different lengths combined
together to form a single slot structure. The antenna has been fed with 50 Ohms CPW, and
the slot structure is to be etched on the ground plane. Performance evaluation of the proposed
antenna design has been carried out using a method of moments based EM simulator, IE3D.
Simulation results show very interesting results. The antenna with two C-slot structure offers a
dual band resonant behavior meeting the requirements of the 2.4/5.2 GHz WLAN. The resulting
percentage impedance bandwidths of the modeled antenna at the center frequencies of 2.51 GHz
and 5.21 GHz are 22.70 (2.29 GHz to 2.86 GHz), and 4.80 (5.11 GHz to 5.36 GHz) respectively. In
addition, the antenna with three C-slot structure possesses a dual frequency resonant behavior
covering the 2.45/5.8 GHz WLAN applications. The resulting percentage impedance bandwidths
at the center frequencies of 2.45 GHz and 5.71 GHz are 11.80 (2.32 GHz to 2.61 GHz), and 7.2
(5.53 GHz to 5.94 GHz) respectively. Parametric study has been carried out to explore the effects
of antenna parameters on its performance. Besides the satisfactory radiation characteristics, the
simple structure of the proposed antenna makes it an attractive choice for antenna designers.
