Design of Planar Monopole Antenna for UWB Applications
A small-size microstrip-fed multi-band planar monopole antenna is presented. The base of the proposed antenna is a Diamond-Shaped Patch (DSP) that covers the Ultra-Wide-Band (UWB) frequency range. The range of UWB is 3.1- 10.6GHz. Using narrow strips in DSP antenna, acting as resonance paths, can be integrated with the multiband antenna. It is shown that by removing the centre part of the DSP antenna, without distorting the UWB behavior, quarter-wavelength strips can be added to the notched region.
