Abstract:
A novel miniaturized design of UWB monopole antenna is presented and investigated for oil pipeline imaging. In the proposed antenna, an annular-ring shaped radiating patch, slotted ground plane and a feed-line embedded with a semicircular stub are used to enhance the bandwidth. The slotted ground-plane has two extended rectangular strips on its two sides to excite the lower frequency resonance. The proposed antenna design exhibits an enhanced bandwidth of 22 GHz from 3 to 25 GHz (for return loss <10 dB) which provides a wide usable fractional bandwidth of more than 157% with a compact size of 15 mm×12 mm. Simulated and measured results are discussed to validate the proposed antenna design with enhanced wide bandwidth performance.
