Abstract: In this study, a reduced size, low profile multiband printed GCPW-fed monopole antenna is presented as a candidate for use in multi-functions wireless communication systems. The proposed fractal antenna structure is based on the tent transformations. The self-similarity of the resulting monopole antenna substructures results in a multi-resonant behavior. To provide a wideband impedance matching and bandwidth enhancement to the antenna performance a grounded coplanar waveguide (GCPW) feed technique has been used. Theoretical performance of monopole antennas based on 1st and 2nd iterations of this fractal geometry has been calculated using a method of moments (MoM) based software, IE3D, from Zeland Software Inc. Results have shown that the proposed monopole antenna design possesses a multi-band resonant behavior with adequate radiation performance with VSWR 2 (return loss -10 dB) throughout the resonating bands. An attempt has been carried out to correlate the proposed antenna dimensions with its resonant frequencies, to serve as an approximate aid in the initial design stage. This makes the presented antenna suitable for use in the modern multi-functions compact communication systems.
