A New Approach for Matching Small Parasitic Superdirective Antennas Using Network Characteristic Modes

Résumé

This paper presents a network characteristic modes based method for parasitic superdirective arrays matching. The proposed method is used for designing a two M-monopole array with a separation distance of d = 0.1 lambda that achieves a near 50 Omega input radiation resistance, resulting in a matched input impedance, and therefore, a substantial increase in realized gain and total efficiency. The designed array shows a maximal directivity of 7.37 dBi and an impedance bandwidth of 23 MHz. The array present a - 1 dB bandwidth of directivity, gain and realized gain respectively of 70 MHz, 70 MHz and 31 MHz.
