Triple notch UWB antenna controlled by three types of resonators

This paper discusses a microstrip fed UWB monopole antenna with a triple notch characteristic. The three notches are designed to occur at the WiMAX frequency range, the WLAN and at a third frequency in the higher end of the UWB range. Each of the three notches is controlled by a different type of resonators and each and every notch can be adjusted without affecting the position or the shape of the remaining two, thus allowing for an antenna design with adjustable, agile S11 response.
