A multi-band antenna which can be used as a passive strain measurement device is presented. The dimensions of the antenna will change when different strains are applied, resulting in changes in the resonant frequencies. The proposed antenna resonates at multiple frequencies. By creating slots on the patch of the antenna, these resonant frequencies shift to a higher or a lower value for different strain...
A simple square loop printed antenna fed by a coplanar waveguide (CPW) is proposed. Considering a return loss criterion of better than 9.5 dB, the antenna operates in two frequency bands: 1.73-2.50 GHz and 3.44-3.87 GHz. These bands represent 36.4% and 11.8% impedance bandwidths respectively. A parametric study has also been carried out by varying the spacing between the ground and the square loop...
A simple and compact planar inverted-F antenna (PIFA) with size of 35 mm ?? 25 mm ?? 6 mm for personal communication handset applications is proposed in this paper. The radiating patch is folded at end and etched with two slits to create multiple resonant frequency bands. The antenna covers following frequency bands: Global System for Mobile communication (GSM900, 880-960 MHz)/Digital Communication...
