Abstract

An ultra-wideband (UWB) monopole microstrip antenna is designed in this
study. The design consists of a radiating triangular patch antenna (TPA) fed
through a 50 Ohm microstrip transmission line (MTL) constructed over a defected
ground structure (DGS). The triangular monopole well is matched to MTL with
inserting a thin strip line. The performance of the proposed antenna is
numerically investigated using method of moments (MoM) and verified through
measurements. Based on the measured results, the antenna operates over large
frequency range of 2.6-18.2 GHz at -10 dB. This makes the design suitable for
UWB applications.  The proposed antenna
has better characteristics in terms of radiation pattern, peak gain and total
efficiency across the operating ultra-wideband frequency range. Furthermore,
the antenna system is suitable for near-millimetre wave applications, since the
operating band reaches to 18.2 GHz.
