| Popis: | PurposeModern wireless communication application requires an antenna system to meet the requirements of miniaturization and wideband characteristic. In recent years, several antenna designs, that meet these requirements, have been proposed in the literature. In this context, the purpose of this paper is to design a new microstrip monopole antenna with a bandwidth enhancement and size reduction for ultra wideband application.Design/methodology/approachThe patch, of leaf of a plant shape, the feed line and the ground plane are printed on the inexpensive FR4 substrate material with permittivity 4.4 and loss tangent 0.02. To obtain optimal dimensions, a parametric study is conducted through numerical computations by using electromagnetic simulators HFSS and CST. A prototype of the optimized antenna is fabricated and subjected to a series of simulations and measurements.FindingsThe measurement results show a −10 dB impedance bandwidth of 6.7 GHz (3.5 GHz-10.2 GHz) which can cover the whole bandwidth requirements of an ultra wideband application. The designed antenna exhibits nearly symmetric and omnidirectional radiations patterns over the operating band, which is a sought-after behavior in microstrip patch antennas and has overall size of 35 × 31 mm2.Originality/valueThe proposed microstrip monopole antenna is very useful for modern wireless communications systems because of its compact size, its capability of covering the whole ultra wideband frequency band and its good radiation characteristics. |
