This paper presents the design of a corrugated tapered slot antenna (TSA) with application to microwave imaging (MI) system for brain stroke detection. The antenna is excited by a stepped transmission line through slotline transition. Corrugations are used to reduce the size of the antenna and also improve its radiation performance. Simulated and measured(More)
A monopole-like bowtie slot ultra wideband (UWB) antenna is proposed and designed for UWB applications. To increase the impedance bandwidth of ordinary monopole patch antenna modifications are made in the patch and ground plane geometry. The antenna is practically fabricated and measured. Simulated and measured results show a good agreement. The designed(More)
A dual band microstrip patch antenna has been designed for technology oriented requirements of high speed wireless local area networks (IEEE 802.11a standard) and other communications systems covering the 5.15-5.825 GHz band. Three parallel slots have been introduced in the radiating patch to get the maximum current distribution on the surface. The position(More)
To enable effective signal detection of human microwave, it is important to design high performance ultra-wideband wearable antenna. Due to its intrinsic complexity, antenna optimization is a nonlinear problem that is expensive to simulate and optimize. In this paper, we propose to optimize tapered slot antenna (TSA) with an improved particle swarm(More)
