Development of ultra-wideband directional microstrip antenna

The development of ultra-wideband (uwb) directional microstrip antenna is to offer solutions for problems related to bandwidth,cost,power consumption,and size generation electronic communication equipment. the uwb allows for high-speed wireless connection through a variety of electronic devices and computer within a certain area. it can be used for internet access and multimedia services with data up to 1 gbps as well as for radar applications,tracking,determining an object’s position. with the development of uwb,the accuracy of the position of an object can be increased either indoors or outdoors. the antenna has an important role in uwb,such as integrated circuit,getting transient characteristics (short impulse response) and the uwb antenna microstrip is design with monopole or dipole antenna. the decline in antenna performance can be prevented using uwb directional microstrip antenna. this research was based on experimental method using a vivaldi microstrip antenna. it used software 3d electromagnetic simulator. the development of uwb directional microstrip antenna radiation characteristics of designs that meet the specifications which have vswr < 2 for the frequency range of 3.1 to 10.6 ghz. © 2017 universiti putra malaysia press.
