Design of Polygonal Slot Antenna with Tapered Strip-fed Monopole for Uwb Applications
A compact wide-slot antenna with microstrip-fed monopole for ultrawideband (UWB) application. The monopole is composed of an elliptic patch connected to a trapezoid one. The radiator patch is attached to a 50microstrip feed line by a smoothly tapered line to enhance the wideband matching. A hexagonal slot is etched from a finite ground plane placed on the other side of the substrate. The antenn...
متن کاملA Miniaturized CPW-Fed Tapered Slot Antenna in Lossy Environment for UWB Application in Breast Cancer Detection
In this paper, a miniaturized coplanar waveguide fed (CPW-fed) tapered slot antenna (TSA) is introduced for breast cancer detection. Here, a modified CPW to slot-line transition structure with an air-bridge is employed to broaden the transition bandwidth and increase the radiation efficiency. Through these applied modifications, negative features of the original TSA (limitation of transition) a...
متن کاملCompact UWB MIMO Ground Linearly Tapered Slot Antenna Decoupled by a Stepped Slot
A very compact ultra-wideband (UWB) multiple-input-multiple-output (MIMO) ground linearly tapered slot Antenna (LTSA) is presented in this paper. On a cost-effective FR4 substrate, it consists of a ground plane and two microstrip feedlines. Its overall dimension is only 22 × 26mm2. To miniaturize the dimension of the antenna, two linearly tapered slots on the ground plane act as the main radiat...
متن کاملCPW-Fed Circularly Polarized Slot ANTENNA with Elliptical-Shaped Patch for UWB Applications
A new design of coplanar waveguide (CPW)-fed antenna with circular polarization (CP) and excellent impedance matching is presented. In this design a pair of circular-shaped slits is applied to opposite corners of the slot for enhancing the impedance matching and realizes bandwidth of 134.43% across 2.98-15.20 GHz for VSWR≤2. Furthermore this structure exhibits axial ration bandwidth (ARBW) of 3...
متن کاملDesign of a Compact Tapered Slot Vivaldi Antenna Array for See Through Concrete Wall UWB Applications
An optimized 1×8 Vivaldi antenna array designed for the lower-band UWB (2-4 GHz) through-wall imaging systems has been developed. Tapered slot antennas were utilized as the array elements and optimized to have a compact size. A one to eight wideband Wilkinson power divider was designed and fabricated to compose the feed network for Vivaldi antenna array. Measured results of the manufactured Viv...
