A Family of Directive Metamaterial-Inspired Antennas

Abstract: Abstract-A new family of metamaterial-inspired monopole antennas designed for GPS operation is reported. By adding a simple Split-Ring Resonator (SRR) into the near-field region of a monopole antenna resonating at 2.45 GHz, we have created a second resonance situated in the L1-band (f = 1, 537 for example) lower than the monopole's one. At this new resonance, the directivity of the structure was enhanced and its profile was reduced. Four SRR-configurations were considered depending on the orientation of the sl… Show more

“…Consequently, the desired properties are typically obtained only in a narrow frequency range. The same issue applies also in 2D artificial structures (e.g., metasurfaces and metamaterial transmission lines) or in structures consisting of single metallic inclusions (e.g., metamaterial inspired-structures) [2][3][4][5][6][7][8][9][10].…”

“…In this article, we report printed planar multiband metamaterial–inspired antennas that are based on the compact augmentation of a driven dipole antenna with two capacitively loaded loop (CLL) elements. Single and multiple CLLs have been used previously as NFRP elements to successfully control the radiation patterns of printed monopole antennas at one and several frequencies. The CLLs are simpler metamaterial unit cells than their split‐ring resonator (SRR) counterparts that have been used in similar applications, e.g., .…”

“…Οι κεραίες αυτές ονομάστηκαν κεραίες βασισμένες στα μεταϋλικά (metamaterialbased) ή εμπνευσμένες από τα μεταϋλικά (metamaterial-inspired). Παρουσιάστηκαν βελτιωμένες κεραίες με αυξημένη κατευθυντικότητα [52][53][54][55][56][57] και αυξημένο εύρος ζώνης [58][59][60]. Όμως, η πραγματική προσπάθεια των ερευνητών επικεντρώθηκε στην εφαρμογή των μεταϋλικών για τον σχεδιασμό συμπαγών και αποδοτικών, ηλεκτρικά μικρών κεραιών.…”
