Design Of Dual Band Microstrip Antenna For Telephony System

Antennas are essential part of communication systems. Without antenna wireless connection become difficult. For effective communication, certain parameters need to be concerned. Depending upon the signal frequency the length of an antenna becomes very large. Microstrip antenna deals with this problem, where equivalent antenna can be designed in small size. This helps in integration of electronic and communication devices. This work presents broadband microstrip antennas for Telephony systems applications. Using co-linear patch design, microstrip antennas are made. These antennas are capable to work with GSM technology. This research also shows how an antenna can be designed within the same size, where antennas are operating in single band as well as multiband
