Small modified printed planar ultrawide band disc antennas with etched ground plane

摘要

Now a days, Microstrip or patch antennas are becoming increasingly useful because they can be printed directly onto a circuit board. Microstrip antennas are becoming very widespread within the mobile phone market. Patch antennas are low cost, have a low profile and are easily fabricated, these antenna structures useful for wireless and mobile communications domain and also we can manufacture with low cost and suitable for handheld devices such as mobiles and Laptops. In this Paper we have designed and proposed printed monopole antenna and also we have mentioned extensive simulation study and how we have utilized the usage of broadband techniques but also how we have achieved the huge bandwidth. We have used simple microstrip line for feeding the antennas and also these proposed antennas are well suitable for UWB frequency band from 3.1 to 10.6 GHz.
