Title: Development of Antenna Arrays and Transmit Receive Module for Radar and Wireless Communication Systems.

Abstract :

Transmit-receive module integrated antenna panels offers an effective solution for modern wireless applications, including satellite communication, radar systems, and wireless networks like 5G, which require phased array antennas. By integrating both transmit and receive channels within an IC and combining it with the antenna into a single panel, the overall system size can be significantly reduced. This integration eliminates the need for separate channels and antennas, thus reducing the number of extra cables and connections, which in turn enhances the system’s efficiency.

In this thesis the focus is on the design of the antenna and the enhancement of its parameters, including bandwidth, beam-width, and gain, which are explored and discussed. Subsequently, the transmit-receive module Integrated circuit (IC) is designed.

Various methods for the improvement of the bandwidth of microstrip patch antenna are explored and designed. To improve bandwidth U slots are integrated in the patch antenna, modified aperture coupled patch antenna is designed, circular patch antenna with partially removed ground and the square patch antenna with increased substrate height to achieve the wide band operation. After bandwidth improvement, methods for improving the beam-width of microstrip patch antenna are studied and applied to design and develop the broad beam-width antennas for wide coverage and wide scanning properties. Microstrip patch antenna arrays are discussed to achieve more gain. Series fed, corporate fed and separate fed antenna arrays are designed and discussed.

After different types of antenna array are designed and analyzed, TRM is designed. X-band transmit receive module at 65 nm CMOS technology is designed and analyzed with EM and calibre analysis. Gain of around 26 dB and 30 dB was achieved for transmit and receive path respectively.
