Planar Inverted 60° Cone Antenna for UWB and Notch Characteristics Response

This paper proposed a planar, low cost, simple, and compact printed microstrip-fed inverted planar 60° cone monopole ultra-wideband antennas with band-notched characteristics. By introducing pair of open stubs or a pair of slots on the sectored conical patch the band notched characteristics can be obtained. The proposed antennas are successfully simulated, designed, fabricated on FR-4 substrate. The measured results show that the proposed antenna with dimensions of 65 mm × 65 mm × 1.6 mm has a large bandwidth over the frequency band 2.00-10.6 GHz with VSWR ≤ 2, except 2.5-3.95 GHz with sectoral antenna having pair of stubs and 3.11-4.71 GHz with sectoral antenna with pair of slots frequency band. The presented antennas shows nearly omnidirectional radiation pattern, stable gain at working frequencies.
