A compact periwinkle flower shaped fractal antenna loaded with split-ring resonator on either side of the feedline is proposed in this article. The proposed antenna consists of partial ground on flipside and a periwinkle flower petal is located on the rectangular patch. The proposed antenna works in multiband i.e., at 4.1GHz,4.5GHz,4.8Ghz(S-band) at 6.7GHz,6.75GHz(C-band) at 9.4GHz(X-band) and at 12.7(ku) i.e., proposed antenna covers almost one frequency at all radar frequency bands. The proposed antenna has been analyzed and maximum gain of 4dB and radiation efficiency of 87 percent is observed.

Abstract A compact balanced bandpass filter (BPF) based on complementary split ring resonator (CSRR) -loaded substrate integrated waveguide (SIW) structure is reported in this paper. Both TE102 and TE201 modes of the SIW cavity can be excited under differential-mode (DM) operation with the proper positions of the balanced feeds. Meanwhile, the CSRR etched on the top layer of the substrate can also be excited by the axial electric excitation. Then, three transmission poles and two transmission zeros (TZs) have been obtained which improve the selectivity of the DM passband. To verify the above design concept, an X-band prototype operating at 8 GHz has been fabricated and measured. A good agreement is observed between the simulations and the measurements.
