The use of mobile phone has increased in the present day with a steady improvement in the technology used. Due to the increase in the functionality of the mobile which makes some components in the phone occupy some space, the need for a compact design of antenna is required which will operate in different frequency bands. The operating environment of a mobile phone varies continuously due to the handling and the proximity of the user's body and hand. The user body in close range with the antenna of the mobile makes the power amplifier of the mobile phone efficiency to suffer from variation in the load impedance, resulting to a variation in the feed-point impedance of the antenna.
