Fringing field in microstrip patch antenna array system

A microstrip antenna array is one of the simplest forms of antennas available. The antenna consists of a single printed circuit board with an RF connector and perhaps an absorptive load. Microstrip antennas can be manufactured very inexpensively now that reasonably priced, closely controlled substrate materials are available. Microstrip antennas are very versatile and are suitable for applications requiring pencil beams, fan beams and omni-directional coverage. They offer a choice between linear polarization and circular polarization, and circuit components may be integrated with the antenna in many instances. Microstrip antennas can be flat or curved to suit the structure to which they are mounted.

Now that microstrip antennas have come of age it is useful to review some of the lessons learned for their design. This article is intended to serve as a practical guide to microstrip array design. Most of the work carried out by the author used experimental models, although the same qualitative understanding is required when using computer simulation techniques. No extensive theory is offered and important theoretical facts are simply stated as required. Where manipulation of data is required the methods are explained but no great detail is provided. The aim is to help the designer to make sensible decisions resulting in a successful product.

This is explained in the text and, in some cases, backed with case examples. THE RADIATING MECHANISM OF A MICROSTRIP TRANSMISSION LINE An example of a microstrip transmission line is shown in Figure 1 and consists of a flat conducting strip suspended above a ground plane. The conducting strip is supported by a dielectric substrate and is normally manufactured by etching copper-clad material using photographic techniques. Microstrip provides an inexpensive and compact alternative to other forms of transmission line, and is used to make devices such as directional couplers, powers dividers and filters. These components are easily integrated with circuit modules such as amplifiers, attenuators and switches. Microstrip circuits were originally confined to lower frequency applications (such as VHF or UHF) because of the apparently uncontrolled radiation, which took place at microwave frequencies. This characteristic was overcome when closely controlled high dielectric constant ceramic substrates became available and radiation was reduced to a tolerable level.

Microstrip has now largely replaced other forms of transmission lines (such as triplate and waveguide) for the manufacture of microwave components and circuits. An exception is in high power applications. The radiation, which occurs in microstrip circuits, is now better understood and is being exploited in the design of microstrip antennas. The key to understanding the radiation process is in the observation that straight lengths of microstrip line do not radiate. Measurements of test pieces using a low dielectric substrate several millimeters thick are found to have low transmission loss even at microwave frequencies.

The radiating patch and the feed lines are usually photo-etched on the dielectric substrate. Microstrip patch antennae radiate primarily because of the fringing fields between the patch edge and the ground plane. For good antenna performance, a thick dielectric substrate having a low dielectric constant (. A microstrip antenna array is one of the simplest forms of antennas available. The antenna consists of a single printed circuit board with an RF connector and perhaps an absorptive load. The antenna consists of a single printed circuit board with an RF connector and perhaps an absorptive load.

The performance is usually limited by the interface with a coaxial line, which may allow radiation. A good example where low radiation is essential is in the use of ultra-large, air-spaced microstrip lines to provide a controlled RF environment for the testing of electrically small antennas. An embodiment is shown in Figure 2 and is known as a form of TEM cell. The device under test is placed inside and comparative measurements of sensitivity are made. Radiation by the cell leads to fluctuations of the field inside as the operator moves around; however, this effect is prevented at frequencies up to the limit where high order modes propagate.

The reason radiation is prevented in straight microstrip line (and occurs in microstrip discontinuities) can be understood by looking at the electric fields shown in Figure 3. The fringing fields along the line are balanced causing the cancellation of any radiated energy. At the end of the line, where there is no balance of electric fields, the discontinuity radiates copiously. Radiation is more intense if wide transmission lines are used and this effect is associated with thick low dielectric constant substrates. Several examples of microstrip discontinuity are given in Figure 4. In most cases electric fields are unbalanced and radiation occurs. An exception is example d, where the junction is perfectly balanced and radiation is prevented.
