Abstract: The digital signal processing revolution began around 1980 as the first dedicated digital signal processors began to appear. Since that time DSP has been incorporated into just about every aspect of modern electronics. Oscilloscopes are no exception. Digital storage oscilloscopes have almost totally replaced analog oscilloscopes. They use DSP in acquisition modes, averaging, interpola...

Introduction The microstrip patch antennas are widely used in modern communication system due to low profile, low weight, low cost However, the antennas suffered from narrow bandwidth and low gain.[6 The major need for modern communication devices is to operate at wider band such as to support high speed internet, multimedia communication and similarly many more broadband services, this is achi...
