Design of Novel UWB Slot Antenna for Bluetooth and UWB Applications

In this article, a novel wideband planar monopole antenna for applications in 2.4 GHz Bluetooth and UWB bands is presented and investigated. The low-profile antenna comprises an approximate rectangle patch for covering the UWB band (3.1~10.6 GHz). A lower pass band, 2.4 GHz Bluetooth band (2.4~2.484 GHz), can be realized by adding a pair of U-shaped parasitic strips bilaterally beside the feed line without affecting its UWB behavior. The proposed antenna is designed and built on a FR-4 substrate, with overall size of 18 mm×32 mm. The simulated and measured results are presented and show that the proposed compact antenna has a stable and good radiation patterns across all the relevant bands.
