Design and Analysis of Reconfigurable Microstrip Antenna for Dual Band Operation in Wireless Applications

This paper gives a portrayal for design and development of a reconfigurable multi-slotted antenna by inserting a slot on the patch with a lumped capacitor (or varactor) located on the edges at slot. The proposed antenna suits for various wireless applications which include 4G, Bluetooth. This antenna is an attractive candidate for important applications like wireless communication such as WLAN, WiMax. Microstrip feeding technique is used to feed the antenna. The proposed antenna enhances the return loss of -19.17dB at 2.34GHz frequency. The reconfigurability of the proposed antenna is achieved using capacitors. This paper manages a method for planning a reconfigurable multi-space receiving wire by stacking an opening on patch with a lumped capacitor situated on the edges of the space. With a settled capacitor area along the opening reductions the capacitance which brings about expansion the full recurrence of the space radio wire. The designs are verified through numerical simulations.
