design and parametric study of microstrip antenna for uwb applications

Since the beginning of the human civilization mankind is trying to communicate with the others. It’s the communication process i.e. the sharing of feelings, emotions and information has made us the greatest creation of God on this green earth. It all started with hand gestures, then sounds. Communication. in wireless communication we mainly exploit the Electromagnetic Spectrum. Earlier systems were narrowband long range systems but in order to extend the use of available spectrum we are now using UWB (ultra-wide band) short range systems which require low power and these are built using in expensive digital components. A microstrip antenna is a narrowband, wide-beam antenna fabricated by etching the antenna element pattern in metal trace bonded to an insulating dielectric substrate, such as a printed circuit board. Microstrip antenna is used for implementing UWB systems as it shows good broadband characteristics. We propose a Slotted MSA (Microstrip Antenna) for UWB (Ultra-Wide Band) applications. The aforementioned antenna is designed using IE3D SOFTWARE. This design consists of a rectangular patch U-shape antenna, two slots have been used which are at the ground. The technique used for feeding is the aperture feeding technique.FR4 substrate has been used because of its lost cost and good reproductivity. The proposed Antennas were successfully designed, simulated and measured showing broadband features, stable radiation patterns and consistent gain. Measured results and graphs show validity of our suggested design.
