Compact Triple Band Notched Pentagonal Shaped UWB Antenna Loaded with Slots and Parasitic Resonator
| Resumo: | Abstract In this paper, a compact, planar printed microstrip line fed pentagonal shape ultra-wideband antenna with triple band-notched characteristics is proposed and investigated. By incorporating a pair of mirrored Γ-shape, a pair of mirrored L-shape slots in the pentagonal patch and bent C-shape parasitic strip at the backside of a patch, the tunable band notched responses are realized. The proposed antenna is fabricated on Rogers RO3003 substrate with permittivity 3.0 and thickness of 0.76 mm. The measured results indicate that the proposed antenna having dimensions of 32 × 24 × 0.76 mm3 has a bandwidth over the frequency band 2.7-10.6 GHz with S11 ≤ -10 dB (VSWR ≤ 2), except in WiMAX band (3.27-3.85 GHz), WLAN band (5.6-5.95 GHz) and ITU-T band (7.84-8.46 GHz). The presented antennas show dipole- like patterns in E-plane and omnidirectional in H-plane, minor group delay variation, and nearly constant gain at operating frequencies. |
