Abstract
In modern communication systems that include third and fourth generations (3G/4G), reliance upon wide bandwidth service is of intrinsic value to users of high data speed. These wideband systems require components such as amplifiers, oscillators and antennas. In this project, we explore different methodologies for the design of components with uniform efficiency across the band. In earlier studies, a multi-feed tightly coupled patch array antenna capable of broadband operation was analyzed and designed. In contrast, this project will focus mainly on the design and fabrication of broadband antenna using a single stage dipole antenna. The design of nonlinear or curved geometry is designed to make available additional degrees of freedom and this permits increased flexibility over control of pattern structure and increase in the bandwidth of operation. The proposed project will include design of broadband curved antenna, simulation of broadband gain and radiation pattern of the designed antenna, fabrication and testing of the curved dipole structure to validate the broadband characteristics. This design will be tried on different antennas in the frequency bandwidth of 900 MHz – 2.5GHz.
