Abstract
The need to produce light weight and cheap
components and devices has been the driving force for macroelectronics.
Electronics that can be stretched has recently
attracted considerable attention. In this work a design of
printed rectangular monopole antenna for Ultra-Wide Band
(UWB) applications is presented. High-frequency structure
simulator (HFSS) is used to design the printed antenna is to
achieve the best reflection coefficient. Moreover, the stretching
effect on the antenna response is studied along x-axis and yaxis.
Also, compact UWB Multiple-Input Multiple-Output
(MIMO) antennas are proposed. In order to enhance
impedance matching and improve the isolation, each UWB
MIMO antenna which consists of two comparable monopole
elements is proposed with different stubs on the ground plane;
the first one is a vertical slotted stub and the other is a ground
slotted stub ended with a rectangular loop. The reflection
coefficient, mutual coupling, peak gain and radiation patterns
have been analysed. The obtained results show that the
impedance bandwidth of the antenna is from 3–15 GHz, less
than -25 dB mutual coupling between the two ports. The size
of the designed antenna is 32 × 18 . As a result, it can be
noticed that the proposed antenna is appropriate for UWB
MIMO systems.
