Design of Planar Inverted F Dual frequency Microstrip Patch Antenna

With the constant change in technology, frequency band reconfigurable antennas are important innovations. The new devices limit the physical space so the need of multiple antennas is eliminated. This is especially vital in mobile devices such as cell phones that receive multiple frequency bands. For this application we used MICROSTRIP PATCH antenna. Dual-band phones can cover GSM networks in pairs such as 900 and 1800 MHz frequencies or 850 and 1900 MHz. For this application in mobile phones PLANAR INVERTED F ANTENNA (PIFA) is widely used. These antennas have principal advantages, their compactness and their low manufacturing costs, in addition to their significant performances. The side-goal of the project is to incorporate the use of SMD components which are used for switching between two frequencies. The benefits of using these antennas are very small package size, high isolation loss, low insertion loss, low power consumption, better efficiency and reflection coefficient. The goal of this project is to check the effect of SMD component and PIF technique on antenna parameter.
