Abstract

Recently studies show that some parameters such as the shapes of antenna patch and the ground plane when geometrically altered, producing changes in the current density distribution of the planar structure and therefore the radiation characteristics. This paper presented a new microstrip fractal antenna that use the technique of inserting slots of shape fractal in ground plane in order to increase the bandwidth and insertion discontinuities in the feed line to reach specific behaviors in three band frequency applications. The FR-4 substrate with dimensions 85.0 x 85.0 x 1.57 mm³ was used. Also, it used different modes of impedance matching in feed line of antenna with changes of the width of the transmission line in order to obtain a variation in the current distribution and consequently the response by impedance bandwidth for S11 ≤ -10dB for standard C-band in receive frequency (3.625 GHz 4.2 GHz) and S-band (2.0 GHz 4.0 GHz).  Good agreement between measured and simulated results is achieved. Proposed fractal microstrip antenna can be easily designed, built and applied in wireless communication.
