Broadband coplanar waveguide‐fed slot antenna for wireless local area networks and microwave imaging applications

Abstract: A broadband CPW‐fed semicircular slot antenna is proposed for 2–6 GHz WLAN (wireless local area networks) and microwave imaging applications. The total dimension of the bidirectional slot antenna is 80 mm by 50 mm and is designed on a 0.5‐mm‐thick Duroid 5880 substrate (dielectric constant = 2.2). The antenna operates from 2 to 6 GHz within VSWR of 2.5:1. The same antenna on a combination rectangular cylindrical cavity with cavity depth of 10 mm provides a directional beam, 11 dB front‐to‐back (F/B) ratio and … Show more

“…Sensors should be designed specifically for lower frequencies to enhance electric field intensities inside biological tissues, due to more penetration inside the tissue when the frequency is relatively low; thus, more useful information of the object can be obtained. Various sensors have been developed for imaging of breast, including open-ended coaxial probe [47][48][49][50][51][52][53][54][55][56][57], tapered slot antenna (TSA) [59][60][61][62][63], bow-tie antenna [64][65][66][67][68][69][70], monopole antenna [71][72][73][74][75][76][77][78], dipole antenna [79,80], waveguide antenna [81][82][83][84], patch antenna and Vivaldi antenna. …”
