Antennas are either massive or miniaturized structures useful for the transmission and reception of signals associated with Electromagnetic (EM) radiation. Although Microstrip Patch Antennas (MSA) are advantageous they exhibit several drawbacks which may impair a faster communication throughput. They mostly display narrow impedance bandwidth amidst other grave issues. This study presents some approaches such as transmission line analysis and modeling for investigating the complexities associated with the MSA configurations given the shortcomings of narrow impedance bandwidth. in other to achieve the associated input impedance for the dual-band E-patch microstrip antenna. It also investigated the fabrication of the E-patch MSA which targeted the operating frequencies of 2.4 GHz and 5.8 GHz for possible range and speed. The fabricated prototype was tested using a high-frequency communication instrument known as the Vector Network Analyzer (VNA) to obtain the return loss and Voltage Standing Wave Ratio (VSWR). This method was done to quantify the reduction of reflections for enhanced Radio Frequency (RF) network output. This work helps to mitigate the challenges encountered when designing and developing microstrip patch antennas having a relatively small size in different configurations.
