Design of a rectangular patch antenna

How to make patch antenna

This is true in general, even for more complicated microstrip antennas that weave around - the length of the longest path on the microstrip controls the lowest frequency of operation. Microstrip patch antennas MSAs have attractive features of low profile, light weight and easy fabrication process. One technique is to use a substrate with a very high permittivity. This is the same principle that applies when noting that increasing the thickness of a dipole antenna increases its bandwidth. There are so many types of radiating patch configuration are available such as the rectangular or square patch, triangular, circular disc, ellipse ,annular ring and pentagon [4]. Patch Antenna Menu All of the parameters in a rectangular patch antenna design L, W, h, permittivity control the properties of the antenna. The efficiency is also increased with a lower value for the permittivity.

It can be analyze using both the transmission-line and cavity models, which are most accurate for thin substrates [8].

Design of rectangular microstrip patch antennas for the 2.4 ghz band

The fact that increasing the height of a patch antenna increases its bandwidth can be understood by recalling the general rule that "an antenna occupying more space in a spherical volume will have a wider bandwidth". The figure 1 shows geometry of proposed antenna. The permittivity of the substrate controls the fringing fields - lower permittivities have wider fringes and therefore better radiation. The wider the patch becomes the lower the input impedance is. Higher values of permittivity allow a "shrinking" of the patch antenna. Decreasing the permittivity also increases the antenna's bandwidth. The substrate has thickness h h o, usually 0.

The developing markets like personal communication systems PCSmobile satellite communications and intelligent vehicle highway systems IVHS and many other suggest that the demand for microstrip antennas and arrays will increase even further [2].

Microstrip patch antenna MSA consist of radiating or conducting patch printed on one side of dielectric substrate material with ground plane on other side [3]. The height of the substrate h also controls the bandwidth - increasing the height increases the bandwidth.

The fact that increasing the height of a patch antenna increases its bandwidth can be understood by recalling the general rule that "an antenna occupying more space in a spherical volume will have a wider bandwidth".

The wider the patch becomes the lower the input impedance is. The following equation roughly describes how the bandwidth scales with these parameters:. As such, this page gives a general idea of how the parameters affect performance, in order to understand the design process.

In this paper rectangular microstrip patch antenna RMSA is analyzed on different dielectric substrate or laminates materials operating in X-band. Patch Antenna Menu All of the parameters in a rectangular patch antenna design L, W, h, permittivity control the properties of the antenna. The impedance of the antenna increases with higher permittivities. Using higher values for permittivity is frequently exploited in antenna miniaturization. Microstrip patch antennas MSAs have attractive features of low profile, light weight and easy fabrication process. It can be analyze using both the transmission-line and cavity models, which are most accurate for thin substrates [8]. Higher values of permittivity allow a "shrinking" of the patch antenna. The substrate has thickness h h o, usually 0. Increasing the height also increases the efficiency of the antenna. As such, this page gives a general idea of how the parameters affect performance, in order to understand the design process. A radiating patch is very thin t 0 0 is the free-space wavelength metallic strip. This is the same principle that applies when noting that increasing the thickness of a dipole antenna increases its bandwidth. Decreasing the permittivity also increases the antenna's bandwidth. The efficiency is also increased with a lower value for the permittivity. The wider the patch becomes the lower the input impedance is.

Rectangular microstrip patch is much attracted due to their simple structure as it one of the simplest patch configuration.
