Zusammenfassung: | A two element, closely spaced array of wideband planar monopole antennas to achieve superdirectivity is presented. In this study, three rectangular plate monopole structures, the simple Planar Monopole element (PM), the Planar Monopole element with Bevel (PMB), and the Planar Monopole element Loaded in its radiating edges with small rectangular Plates (PMLP) are considered as the array elements. In each case, the spacing and phase of excitation between the two elements is adjusted to achieve the highest directivity over the widest frequency band. It is shown that the PMLP antenna with element spacing of 2 cm can produce 7.6-10.1 dB of directivity over the 3-8 GHz band. This antenna has an efficiency of 60-91% over the bandwidth. Simulation and experimental results are provided and discussed. |
