Reformation of WLAN Feeler by Incorporating Varactor Diode with Negative Media Structure
Abstract: AbstractIn this manuscript, authors proposed a negative media structure with Varactor diode to reform the rectangular microstrip patch antenna parameter to a great extent. Initially basic feeler was designed and simulated, and then parameters were enhanced by implementing negative media structure. It has been observed that negative media is not sufficient to improve the parameters therefore Varactor diode was introduced to get the required improvement. This proposed design of feeler …
