The structure of rectangular monopole antenna of compact size is presented. The antenna consists of a rectangular
patch with inset feed, so that the impedance matching is improved. In addition, rectangular shaped slots are introduced to patch
to change the surface current paths to spread more uniformly and thus bandwidth of the proposed design is enhanced.
Furthermore parasitic elements are added to design structure. The antenna is compact having size of 17.5 × 21.5 mm. The
partial ground plane has been modified with a centre notch and edge trimming. The antenna operates over frequency range
from 3.51 GHz to 14.14 GHz having bandwidth of 10.63 GHz
