Reconfigurable antenna thesis

In this paper, efficient and compact frequency reconfigurable 9-shape monopole antenna has been designed using an FR4 substrate of thickness 1. The absence and presence of a small metal piece has been used to imitate the off-state and on-state of the PIN-diode.

Our prices are affordable and fast delivery of completed content is done through email. Geometry The geometry and structural dimensions of the designed 9 shaped monopole antenna for Wi-Fi 2. In our group, we have developed a continuously reconfigurable antenna at GHz by monolithically integrating the paraffin PCM capacitors with a slot antenna.

He achieved his M. The simulation and measurement results agree well with each other. We understand that many students have a low budget to spend.

By integrating the radiating element with different types of switches RF-MEMS, lumped elements, varactor diodes and optical switchesthe desired resonance frequency can be obtained. The simulated refection coefficient of this antenna shows dual band and triple band from 2 GHz to 5.

The antenna is reconfigured using a single switch SW to obtain dual band 2. Micrograph of the fabricated reconfigurable antenna.

This design is used for overlay cognitive radio in which one antenna is for sensing and other for communication.

Section 2 describes the designing procedure and geometry of 9-shaped monopole antenna. The third design is proposed for underlay cognitive radio system in which UWB antenna is used which radiate at very low power.

In terms you worry about the price, we can promise the most affordable pricing policy ever. Meaning, you choose the writing professional you feel is qualified to complete your request.

For further clarity the 3D directivity far-field plots are shown in Fig. The switchinh states are listed in Table 2. The log periodic is reconfigured by placing switches between the patches and the feed line whilst the Vivaldi antenna has switched resonators controlling the current in the edges of the tapered slots.

The resonant lengths and guided wavelengths are related as: Furthermore, the work has been extended to study a reconfigurable DRA linear array where several designs have been investigated including single and dual-slot for two and four-element linear arrays.
