Binary GA for Sidelobe Reduction and Null Steering in 5G Array
Abstract: This paper presents a comprehensive performance evaluation of a Binary Genetic Algorithm (BGA) for optimizing radiation characteristics of an active phased array antenna used in fifth-generation (5G) wireless communication systems. The primary objective is to achieve effective null steering while maintaining the desired main beam direction and simultaneously reducing the side lobe level (SLL). These improvements are essential for minimizing co-channel interference, enhancing spatial selectivity, and improving the Signal-to-Interference-plus-Noise Ratio …

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 …
