【 摘 要 】

In this paper, two planar Frequency Selective Surfaces (FSS) with dissimilar configurations along with monopole antenna exhibiting dual-band response at 3 GHz and 5.5 GHz is presented. One of the surfaces with two reflectors is reflective at 5.5 GHz and transmissive at 3 GHz, whereas the response is opposite for the FSS in another flat reflector. Accordingly the antenna exhibits directive radiation at both the frequencies, however in two opposite directions. Unit cell of the FSS at 3 GHz is on the order of $\lambda _{\mathrm {g}}$ /11, leading to low-profile design. With different orientations of the reflectors, beamwidths at 3 GHz and 5.5 GHz are different leading to different peak gains of 7.1 dBi and 12.2 dBi respectively. The composite antenna-FSS with a dimension on the order of $1.1\lambda \times 1.1\lambda \times 0.2\lambda $ exhibits diverse beam radiation. The radiation at 3 GHz can be used in applications involving wide coverage area, whereas at 5.5 GHz the antenna can be used in applications involving smaller beamwidths such as satellite communication, Ground Penetrating Radar etc.
