In this paper, a compact CRLH antenna which consists of an LH line and an RH line which have different frequencies is presented. Thus dual band operation is possible, and the frequencies can be easily changed by altering LH or RH line parameters. Impedance matching can be adjusted using the stub length. Because of its small size, printed form, dual band operation, this antenna can be utilized in mobile...
This paper introduces a suspended stripline over mushroom-like SMPs that has excellent band stop filter characteristics, and apply it to the conventional DFDP antenna in order to enhance isolation. Since the structure of the suspended stripline over the SMP provides strong coupling between the feedline and the SMP, a significant skirt rejection band and near 0 dB the insertion loss outside the rejection...
In this paper, we have presented novel thin frequency selective surface (FSS) superstate - as an alternative to the conventional FSS superstate which is thicker - for dual-band directivity enhancement, and demonstrated that the directivity of the fabricated antenna with a 20 times 10 FSS superstate increases to 19.67 and 21.38 dBi, respectively, at the two frequency bands of interest, and that these...
