Analysis of Multilayer Patch Antenna

This paper analyzes the stacked patch antenna. The anticipated antenna employments gap coupled procedure. The frequency can be adjusted by switching, which can underpins numerous frequency ranges between 2 GHz to 6 GHz with ideal return loss and fine execution. The proposed antenna improves the assembly of aperture-coupled multilayered stacked patch to extend the transmission capacity. This plan employments diverse structures of the gap openings, is engraved onto the ground plane couple with nourish line and stacked fix. The gap spaces are utilized to emanate the waves for the particular transmitting patches to realize the recurrence re-configurability. In ON state the radio wire is anticipating its working point at double frequencies as 3.2 GHz and 4.2 GHz. In OFF state the radio wire can reverberate at 5.3 GHz. These frequencies are well reasonable for higher recurrence applications like WLAN and Wi-MAX. Keywords— Reconfigurable antenna, Microstrip Patch, Radiation pattern, S-parameters, Stacked patch
