Abstract

With the advent of practical implementation of multiple input multiple output technology, several constraints have come into picture, one of them is to define strategies to place multiple antennas on transmitter and receiver side in such a way, that they provide least interference with each other. The locations, at which the antennas are to be placed, are not always suitable to place multiple antennas at desired positions. To overcome this problem, MIMO antennas with low vertical beamwidth are designed and placed strategically inside a single radome. This solves the problem of placement of antennas to a great extent. (A. Ismahayati, P.J. Soh, R. Hadibah, G.A.E Vandenbosch). In this thesis to design such antenna, firstly a dual band microstrip antenna is designed which radiates efficiently in both the WLAN bands. This antenna is designed using a copper sheet of 0.5mm thickness. The dual band characteristics are achieved by cutting two slots in the sheet to create two dipoles, one for each frequency band. (Ahn, J., Kim, S., Lee, M., and Kim, Y.). This type of antenna solves the problem of location constraint, which is faced when multiple antennas are to be placed at transmitter and receiver side in such a way, that they provide least interference with each other. The locations, at which the antennas are to be placed, are not always suitable to place multiple antennas at desired positions. To overcome this problem, high gain MIMO antennas can be used which are capable of accepting input from multiple sources without causing interference with each other. This solves the problem of placement of antennas to a great extent. (Alhaddad, A.G., Abd-Alhameed, R.A., Zhou, D., See, C.H., Elfergani, I.T.E., Excell, P.S.). The aim of the research undertaken in this thesis is to develop a high gain fractal antenna which is able to cater with the needs of future communication standards for high data rates and reliable performance at the same time. The developed antennas solve the problem of location constraints of placing multiple antennas in a MIMO system. (Amer Basim Shaalan).
