Professional Experience

Project Name : THEORETICAL AND EXPERIMENTAL ANALYSIS ON THE DESIGN OF COMPOUND RECONFIGURABLE REFLECTARRAY ANTENNA

WITH AN INTEGRATED ELECTRONIC CONTROL SYSTEM

Applications : Uplink and downlink Satellite Communication Domain : Antenna

Technologies : CST software.

Project description:

This project aims to present the design and fabrication of a reflectarray antenna with compound reconfiguration for improved radiation performance and reliable long-distance communication. This project will demonstrate the construction of a reconfigurable reflectarray antenna capable of working in the X band, downlink and uplink frequencies of Ku band for the first time. The performance of the reflectarray depends on the performance of the elements in the array. Several novel radiating elements with considerable size reduction for applications in X and Ku band will be developed. These elements will be integrated with PIN diodes for instantaneous switching of the frequency bands. The most critical task in the project is to achieve electronic beam scanning across all realized frequency bands. A varactor diode tuning mechanism is proposed to scan the beam. By changing the ON/OFF states of PIN diodes, the relative phase difference Resume of Vidhyashree S Page 3 of 4

between the two elements in the array is adjusted resulting in tilted beam along the desired direction. Since PIN diodes are used for both frequency reconfiguration and beam scanning, a simple electronic control system with microcontrollers and shift registers will be used. The project will conclude with the development of a compound reconfigurable reflectarray antenna with integrated electronics for applications in space research, satellite communications and RADAR systems.

Responsibilities:

• To theoretically analyze and identify the various factors influencing the bandwidth and radiation performance of the reflectarray antenna.

• Rigorous analysis of different unit cell structure along with dependency of different substrates to be incurred for structure development.

• To design a compact, novel radiating element operating in the X band, downlink and uplink frequencies of Ku band; and to perform phase characterization using infinite array approach. The integrated unit cell will conserve space and hence enables the construction of a large reflectarray.

• To construct a frequency reconfigurable reflectarray antenna operating in the X band, downlink and uplink frequencies of Ku band using PIN diodes. The reflection property of the designed unit cell is altered by controlling the ON/OFF states of the PIN diode. In the OFF state, the reflectarray works at Ku band and in the ON state, X band operation is realized.

• To realize beam steering/beam scanning property in the frequency reconfigurable reflectarray using varactor diodes. The phase tuning mechanism of the varactor diode dynamically alters the capacitance value by which, beam scanning is made possible.

• To fabricate and to measure the radiation performance of the compound reconfigurable reflectarray antenna in a shielded anechoic chamber to validate the theoretical results.
