| Ringkasan: | In wireless communication systems, interference
becomes a major problem in limiting the quality of the
transmitted and received signals. A common problem in wireless
communications is to eliminate the interference signal that is
mixed with the original signal. Thus, adaptive beamforming is
proposed to eliminate the interference signal. This paper presents
an adaptive antenna using a slotted patch antenna for WLANs
operated at 2.4 GHz. A reactively steerable antenna concept has
been applied. A downhill simplex algorithm is used to maximize
the cost function. The radiation pattern of the antenna is
controlled by the reactance value connected to each port. From
numerical simulation, null is performed for the incoming
interference. |
