“…This positive reviews can be attributed to the relative ease-of-implementation, adaptation and flexibility in terms of frequency, pattern and polarization [1][2][3][4][5]. In a multipath fading environment, it has been suggested to hold an antenna that can indicate the primary shaft to the desired coverage area while slimming down the unwanted beam in other charges, therefore mitigating the multipath propagation, consequently improve the channel capacity [6][7], several reconfigurable antennas have been investigated to suit different applications employing different feeding techniques such as microstrip line feeding [8][9], CPW to slot-line feeding [10], Antipodal feed [11]. Furthermore, different studies have been conducted on a switching microstrip element to steer the beam, in [12], a novel pattern control antenna was designed to guide the pattern null with a beam of 64º centered at broadside direction and provided a depth nulls greater than 18dB.…”

Vivaldi antenna has b een considered as a mitigation to the scattering effect of an antenna. However, the current performance of Vivaldi antenna suffers from multipath effect, interfering signals and radiation pattern control. This paper proposed an improved Vivaldi antenna which combined triple radiating slot to enab le control of radiation pattern features. This is accomplished b y controlling the position of the radiating element through the asymmetric arrangement of ideal switches to steer the b eam in three desired-directions. The Using operating frequency lied b etween 900 MHz and 2.5GHz, the proposed design was fab ricated and tested. Depending on the radiating element, the proposed anten na covered ab out ±90º with an almost equal gain at the three different focal in contrast to ±45º coverage of traditional rectangular microstrip antenna b eam. The results satisfied pattern reconfigurab ility and the proposed design can b e very useful for wireless communications where multipath fading prob lems are frequently encountered.
