“…This distance is shorter than that required in [4,5], and [9]. A study on return loss versus spacing between the fed patch and radome reveals that the present structure can be used either to increase the bandwidth or gain of the fed patch.…”

Abstract-A method to enhance gain of a circularly polarized (CP) microstrip patch antenna is proposed. We etch coupled square-shaped split ring resonators (CSSSRRs) on both sides of a superstrate which is separated from the patch by an air layer. Thickness of the air layer is around 0.1λ, which keeps the radome in low profile. Open gaps of each CSSSRR on opposite sides of the superstrate are orthogonally oriented to each other. This unique orientation allows the radome not only enhance gain but also maintain good CP performance.

“…This half wavelength spacing is also used to enhance gain in many partial reflection antennas [9,[11][12][13]. In [9], a metallic sheet with square holes etched on a thin membrane was used as a superstrate. It was reported that the spacing from the patch to the radome requires a half wavelength to achieve a maximum gain.…”

“…EBG technology designs for an only band already exist and consist of a single superstrate EBG layer [1][2][3]. Multiband antennas designs with EBG technology are considerably more complex, their complexity increasing along with the closeness of the working frequencies.…”

EBG superstrate based antenna designs can find its applications in Geosynchonous Satellite Navigation (GSN) System Antennas, since they allow to reduce the number of radiating elements while keeping the required high directivity and circular polarization. Their use will considerably simplify the feeding network and simultaneously reduce the antenna mass and volume.A dual layer EBG superstrate which can be easily tuned to the desired frequencies is presented in this paper. The design has been optimized to comply with the navigation antenna requirements of Wide Area Augmentation System (WAAS) application in L1 and L2 bands.

“…Consequently, the second layer (polarizer layer) can be replaced with another metamaterial cover layer, which in turn results in higher directivity. Moreover, in contrast to the previous directive circularly polarized antennas [10][11][12][13], polarization state of the directive antennas using our proposed metamaterial cover can be mechanically changed regardless of the feed mechanism. In this paper a useful guideline has been established as how to use the magnitude and phase of the transmission coefficient to identify the operational frequency band of the directive circularly polarized antennas based on polarization dependent metamaterial covers.…”

“…To obtain directive circularly polarized antenna, various types of metamaterial antenna have been proposed in the literature [10][11][12][13]. It was demonstrated in [10,11] that the directive circularly polarized antenna can be realized by metamaterial antenna with a circular feed. A major limitation of this method is inability to tune mechanically.…”

Abstract-Metamaterial covers exhibit inimitable electromagnetic properties which make them popular in antenna engineering. A traditional metamaterial cover has an identical transmission phase for a normally incident plane wave regardless of its polarization state. The purpose of this research is to show the possibility of using a polarization dependent metamaterial cover to change the polarization state of the incident plane wave. Novel polarizationdependent metamaterial (PDMTM) covers, whose transmission phases for two principal polarizations are different, are presented. A full-wave FDTD numerical technique developed by the authors is adopted for the simulations.
