Abstract
In this thesis a study of novel antennas using metamaterial concepts is presented. The main focus is loading antennas with metamaterial elements to fulfill the design speci- fications of different novel applications implemented on different technology platforms (i.e. conventional PCB and CMOS). The antennas are targeting Long Term Evolu- tion (LTE), Wireless Body Area Network (WBAN) and phased array applications. The metamaterial elements are Composite Right Left Handed (CRLH) unit cells, double layer Artificial Magnetic Conductor (AMC), Complementary Split Ring Resonator (CSRR) and Electromagnetic Band Gap (EBG) structures.
The thesis is divided into seven chapters as listed below:
Chapter 1
This chapter presents the motivation and the contribution of the work in this thesis and the thesis organization.
Chapter 2
This chapter includes the basic definition of metamaterial and its application in antenna design. A literature review on the concept of Composite Right/Left Handed (CRLH), Artificial Magnetic Conductor (AMC) and Electromagnetic Band Gap (EBG) loading of antennas is presented.
Chapter 3
This chapter presents a systematic design approach for multi-band monopole antenna loaded with Composite Right/Left Handed (CRLH) unit cells. In addition a 5-band monopole antenna loaded with three CRLH unit cells for LTE application is proposed. The proposed antenna is characterized by omni-directional radiation pattern at the five operating frequencies.
Chapter 4
This chapter discusses the limitations of designing CMOS on-chip antennas for Wireless Body Area Network (WBAN) applications. Guidelines to design efficient antennas in CMOS technology characterized by lossy silicon substrate that has a thickness slightly smaller than λ/4 of the radiation frequency are also introduced. In addition the proposed guidelines are investigated in the design of a dipole and monopole antennas that operate at 60 GHz in 65 nm CMOS technology.
Chapter 5
This chapter introduces the characteristics of T M11 mode in patch antennas and its advantages in WBAN applications. Two miniaturized single band designs and two dual band designs are proposed. The antennas are characterized by quasi omni-directional radiation pattern in the antenna plane. In this chapter as well a novel 2D periodic EBG structure is proposed. It provides 30% antenna size reduction.
Chapter 6
This chapter combines the concepts discussed in chapter 3 to chapter 5 in designing new dual band phased array antenna. A case study on the FCC short range radar (SRR) and long rang radar (LRR) applications is studied. A low frequency prototype for antenna characterization is also proposed.
Chapter 7
This chapter concludes the thesis work with possible directions for future work.
