Abstract

In this research article, a compact (12 × 20 mm2) triangular shaped monopole dual-band antenna is presented for 2.4 GHz Bluetooth/WLAN and ultrawideband (UWB) applications. The proposed geometry consist of a simple triangular shaped radiating patch for achieving UWB characteristics and a quarter wavelength inverted L shaped strip attached to the patch for achieving second operating band at 2.45 GHz for Bluetooth/WLAN applications. The first operating band characteristics can be controlled by changing the electrical length of the strip. To enhance the impedance bandwidth of second operating band, an equilateral triangular shaped cut has been introduced in the patch. The measured results (S11 ≤ −10 dB) demonstrates that the proposed antenna exhibit dual frequency operation from 2.4 to 2.52 GHz (Bandwidth of 120 MHz) and from 3.2 to 10.6 GHz (Bandwidth of 7.4 GHz). The proposed very small dual-band antenna has omnidirectional radiation patterns, peak gains and radiation efficiencies across both the operating bands.
