Tremendous advancement in the field of Radio-frequency were developed through Micro-fabrication techniques, these technologies miniaturize device in a micro-scale behavior for improved device performances. These technologies are developing rapidly due to its distinct features and wide usage in various applications ranging from switches to sensing devices. The principal behind this work is to build a MEMS based Reconfigurable DMTL phase shifter based on RF MEMS switch with improved device phenomenon like switching speed, low actuating voltage, losses and stress factors. The RF switch is build in a series behavior through co-planar waveguides. Generally switching speed is a major concern in RF MEMS devices because of the presence of the actuating elements within the structure which in turn hinders the device ability to function. The phase shifter designed helps in improving the overall switching speed of the device without electrical or dimension alternation of the device. In this paper, we are implementing a PUSH PULL based RF MEMS reconfigurable switch which was structurally altered based on triangular cantilevers in order to enhance the device switching speed. This would develop and enable better application in terms of reconfigurable phase shifter which can be operated at the wider bandgap applications. Even the resonant frequency enhancement was made which provokes an increase of 13% in terms of the switching speed.
