Abstract / Description

In this paper a super-wideband (SWB) monopole antenna design is presented with integrated triple-band notching characteristics. The proposed antenna comprises a standard circular patch which is loaded with various slot artifacts that include multiple split-ring resonators (SRR), a rotated Gamma-shaped slot, and embedded in the feedline is a rotated S-shaped slot. The ground-plane of the antenna is truncated. The SSR slots excite band stop function at the WiMAX bands. The Gamma-shaped slot and the S-shaped slot in the feedline introduce band notches in the L, S and X-bands. With this technique notch bands can be inserted at low frequencies such as L-band without affecting the antenna size. The proposed planar antenna is relatively small having a surface area of 20 × 24 mm2. The measured results confirm the proposed antenna has an impedance bandwidth between 0-14 GHz for which the return loss ≤-10 dB, and in the non-notch regions of the spectrum the antenna has a gain of 5.5 dBi and efficiency of 92%. The radiation pattern of the antenna however varies with frequency but maintaining a wide coverage. The radiation pattern in the E-plane is partially omnidirectional at lower frequencies however become progressively multidirectional with increase in frequency. The H-plane radiation pattern is quasi-bidirectional and with increase in frequency the pattern changes but remains essentially quasi-bidirectional.
