CHAPTER ONE

Introduction

Microwave integrated circuits (MICs) were introduced in the 1950s. Since then,

they have played perhaps the most important role in advancing the radiofrequency

(RF) and microwave technologies. The most noticeable and important milestone

was possibly the emergence of monolithic microwave integrated circuits (MMICs).

This progress of MICs would not have been possible without the advances of

solid-state devices and planar transmission lines. Planar transmission lines refer to

transmission lines that consist of conducting strips printed on surfaces of the trans-

mission lines’ substrates. These structures are the backbone of MICs, and represent

an important and interesting research topic for many microwave engineers. Along

with the advances of MICs and planar transmission lines, numerous analysis

methods for microwave and millimeter-wave passive structures, in general, and

planar transmission lines, in particular, have been developed in response to the

need for accurate analysis and design of MICs. These analysis methods have in

turn helped further investigation and development of new planar transmission lines.

This book presents the Green’s function, conformal-mapping, variational,

spectral-domain, and mode-matching methods. They are useful and commonly

used techniques for analyzing microwave and millimeter-wave planar

transmission lines, in particular, and passive structures, in general. Information

for these methods in the literature is at a level that is not very suitable for

the majority of ﬁrst-year graduate students and practicing microwave engineers.

This book attempts to present the materials in such a way as to allow students

and engineers with basic knowledge in electromagnetic theory to understand and

implement the techniques. The book also includes problems for each chapter so

readers can reinforce and practice their knowledge.

1.1 PLANAR TRANSMISSION LINES AND MICROWAVE

INTEGRATED CIRCUITS

Planar transmission lines are essential components of MICs. They have been used

to realize many circuit functions, such as baluns, ﬁlters, hybrids, and couplers,

as well as simply to carry signals. Figure 1.1 shows some commonly used planar

transmission lines and Table 1.1 summarizes their properties. Each transmission

line has its own unique advantages and disadvantages and, depending on circuit

types, either an individual transmission line or a combination of them is needed

to achieve desired circuit functions as well as optimum performances. The most

viable planar transmission lines are perhaps the conventional microstrip line

and coplanar waveguide (CPW), from which many other planar transmission

lines have evolved. Multilayer planar transmission lines, such as that shown in

Fig. 1.2, are especially attractive for MICs due to their ﬂexibility and ability

to realize complicated circuits, ultimately allowing very compact, high-density

circuit integration. They also allow thin dielectric layers to be deposited on

conductor-backed semiconducting substrates for achieving ultracompact MICs.

Furthermore, multilayer transmission lines have signiﬁcantly less cross talk and

distortion via appropriate selection of dielectric layers.

There are two classes of MICs: hybrid and monolithic circuits. Hybrid MIC

refers to a planar circuit in which only parts of the circuit are formed on surfaces

of the circuit’s substrates by some deposition schemes. A typical hybrid MIC has

all the transmission lines deposited on the dielectric surfaces, except solid-state

devices such as transistors and other passive components like capacitors. These

solid-state devices and passive elements are discrete components and connected to

the transmission lines by bonding, soldering, or conducting epoxy. The substrates

of a hybrid MIC are generally low-loss insulators, used solely for supporting the

circuit components and delivering the signals. Advantages of hybrid MICs include

small size, light weight, easy fabrication, low cost, and high-volume production.

In practice, hybrid MICs are normally referred to simply as MICs. Figures 1.3–1.7

show photographs of some hybrid MICs employing planar transmission lines.
