The Chapter begins with a discussion of transmission line theory. It describes the mismatch that can occur between two TEM transmission lines which have identical characteristic impedance, but mismatched fields. When examined in terms of distributed circuit analysis, it is clear that a mismatch can occur. Transmission line theory rests on a number of assumptions which are well described by Chipman (1968), and these assumptions are considered next. The Chapter goes on to look at the L-C lattice balun, the coupled microstrip transmission line balun, the microstrip transmission line Marchand balun, and the microstrip branchline (ladder ) balun.

The MM-wave frequency spectrum between 30 and 300 GHz is referred to as the extremely high frequency (EHF) band. Within and near to this, commercial millimeter wave frequencies are from 20 to 80 GHz approximately. Also, automotive collision avoidance radars operate at 24 and 77 GHz. The Chapter considers general millimeter wave design and goes on to discuss corporate-fed patch arrays, giving examples at 28 GHz and 60 GHz.

The two analysis methods for rectangular microstrip antennas which are most popular for CAD implementation are the transmission line model and the cavity model. In this section the author will address the least complex version of the transmission line model. The popularity of the transmission line model may be gauged by the number of extensions to this model which have been developed.

The circular microstrip antenna is analyzed by developing the field equations within the antenna in terms of Bessel functions. When the order of the Bessel functions is 1, the antenna radiates normal to the surface on which the antenna is mounted. Equations are developed for calculation of radiation patterns, impedance, bandwidth and efficiency when the antenna is operating in this mode. Curves are provided to assist in the design of a circular microstrip antenna.
