Design of a rectangular patch antenna

The physical length of a half-wave dipole is slightly less than half a wavelength due to end effect. The speed of propagation in coaxial cable is slower than in air, so the wavelength in the cable is shorter. The velocity of propagation of electromagnetic waves in coax is usually given as a percentage of free space velocity, and is different for different types of coax. Radios typically are designed for 50 Ohms impedance, and the coaxial cables transmission lines used with them also have 50 Ohms impedance.

Prashant S Mahajan was born in Microstrip antennas are the most suited for aerospace and mobile applications because of their low profile, light weight and low power handling capacity.

These antennas can be designed in a variety of shapes in order to obtain enhanced gain and bandwidth for dual band and tri-band operation. The design parameters of the antenna calculated using the transmission line model.

It is a mean of transmitting and receiving radio waves. In another words antenna is transition structure between free space and guided device. The guided device or the transmission line may take the form of the coaxial line or a hollow pipe waveguideand is used to transport the electromagnetic energy from the transmitting source to the antenna or from antenna to the receiver.

RF and microwave technologies are rapidly finding their way into commercial applications.

Industrial applications such as satellite data transfer, vehicle tracking and paging systems have been among the first to be developed.

The intelli- gent vehicle highway of the future will guide us through traffic jams and systems using Global Positioning System GPS will tell us about our location.

From being a tech- nology that had its utilization mainly in telecommunications and radar applications, it is today the forefront technology used for wireless applications. As a consequence, recent years have seen rapid changes in RF techniques as well as technology. This trend is continuing enabling the use of increasingly higher RF frequencies with their inherent advantages of smaller component size and larger bandwidth.

In particular, the use of planar circuit architecture has opened up new opportunities in terms of reduction in weight, volume, power consumption as well as extension of operating frequencies.

Microstrip design is a new era which satis- fies all above requirements. A microstrip antenna consists of conducting patch on a ground plane separated by dielectric substrate. This concept was undeveloped until the revolution in electronic circuit miniaturization and large-scale integration in After that many authors have described the radiation from the ground plane by a dielectric substrate for different configurations.

The early work of Munson2 on microstrip antennas for use as a low profile flush mounted antennas on rockets and missiles showed that this was a practical concept for use in many antenna system problems.

Various mathematical models were developed for this antenna and its appli- cations were extended to many other fields.

The number of papers, articles published in the journals for the last ten years, on these antennas shows the importance gained by them. Low dielec- tric constant substrate materials are generally preferred for maximum radiation.

The conducting patch can take any shape but rectangular and circular configurations are the most commonly used and modeling, and workers were turning their attentions to improving antenna performance features (e.g., Figure 1 shows the geometry of the basic aperture coupled patch antenna.

The radiating microstrip patch element is The original aperture coupled antenna used a single rectangular patch.

Since then, workers have successfully. A rectangular patch as used in such an antenna is shown in Fig.
