The bottom layer is the ground plane that Figure 2. Proposed rectangular micro strip patch Antenna using HFSS covers the rectangular shape substrate with a side of This antenna has been able to achieved the desired value of the VSWR of 1.

Simulated results of 3D, EH plane pattern are shown in figure5. The proposed antenna can cover WLAN applications. Figure 3. Figure 6. The return Loss Figure 4.

IJE Figure 5. Rectangular micro strip patch antenna design enclosed inside radiation Air-Box. Figure 7. The VSWR of studied antenna.

From the 2. Radiation pattern refers to the direction of the results obtained, we could observed that the designed antenna electromagnetic waves radiates away from the antenna. It is a is having a band frequency operation of 2.


The voltage VSWR standing wave ratio rectangular micristrip patch antenna as the function of space is 1. This indicates the impedance matching between the field co-ordinate. From the simulated analysis of the solution set up and the load and ,the value should be equal to 1 in an ideal of HFSS, the solution frequency was set to 2.

In addition there are two types of fields namely, 5. By setting the EH Plane, the far field radiation The antenna is having return loss of This designed antenna is simulated on HFSS software. Similarly, the values of theta start from and stop For this antenna, a sufficient band-width was achieved by at with a step size of 1.

The values of phi and theta are utilizing microstrip line technique, the desired frequency of good from the simulation results as shown in the radiation 2. In actual fact, a microstrip patch antenna achieveable. The designed microstrip antenna is optimized to radiates normally to its patch surface. The radiation patterns of cover WLAN. We sincerely thank our supervisor Prof. Radiation Pattern and encouragement during our research. James, P. Handbook of microstrip antennas, I.

December Related Papers. By Rajeev Shankar Pathak. By Alpesh Vala. Thus the microstrip antenna has a very low profile and can be fabricated using printed circuit photolithographic technology.

The radiating patch may be square, rectangular, thin strip dipole , circular, elliptical, triangular or any other configuration. There are many configurations that can be used to feed microstrip antennas. The four most popular are the microstrip line, coaxial probe, aperture coupling and proximity coupling.

Design and Implementation of Multiband Microstrip Patch Antenna for Wireless Applications

There are mainly two analysis methods for patch antennas- transmission line model and cavity model. A large number of Fig 1: Microstrip antenna configuration microstrip parch antenna have been studied to date.

These patches are used Coaxial-Line feed is feeding method in which the inner for the simplest and the most demanding applications. The circular patch antenna has the plane. Advantage of coaxial feeding is easy to advantage of their radiation pattern being symmetric. A fabricate, easy to match, low spurious radiation and its rectangular microstrip patch antenna in its simplest form is disadvantage is narrow bandwidth and more difficult to shown in figure3.

Coaxial probe feed patch antenna The microstrip feed line is easy to fabricate, simple to match by controlling the inset position and rather simple to model.

It is a conducting strip, usually of much smaller width compared to the patch. However the disadvantage of this method is that as substrate Fig. Structure of rectangular patch antenna thickness increases, surface wave and spurious feed radiation increases which limit the bandwidth. The characteristics of microstrip patch antenna, microstrip slot antenna and printed dipole antenna are compared in Table 1. Microstrip line feed patch antenna and circular triangular shape 5 Dual Frequency Possible Possible Possible The aperture coupling consists of two substrates operation separated by ground plane.

This arrangement allows independent optimization of the III. Feeding Techniques feed mechanism and the radiating element. A high dielectric material is used for the bottom substrate and There are many configurations that can be used to feed thick low dielectric constant material for the top microstrip antennas. The four most popular are the substrate. The ground plane between the substrates microstrip line, coaxial probe, aperture coupling and also isolates the feed from the radiating element and proximity coupling.

The various advantage and disadvantage are given in Table3.

Advantages and disadvantages of patch antenna Sr. Advantage Disadvantage 1 Low weight Low efficiency Fig6: Aperture coupled feed patch antenna 2 Low profile Low gain 3 Thin profile Large ohmic loss in the feed Proximity coupling has the largest bandwidth, has low structure of arrays spurious radiation but fabrication is difficult. Length of 4 Required no cavity Low power feeding stub and width to length ratio of patch is used backing handling capacity to control the match.

Its coupling mechanism is 5 Linear and circular Excitation of capacitive in nature. Conclusion Fig6: Proximity coupled microstrip patch antenna A theoretical survey on microstrip patch antenna is presented in this paper.

After study of various The major disadvantage of this technique is that it is research papers it is concluded that low gain and low power difficult to fabricate due to two dielectric layers that handling capacity can be overcome through an array need proper alignment and also there is increase in configuration and slotted patch. Some factors are involved in antenna thickness. Comparing the different feeding techniques different merits are compared with conventional microwave Characteri Micro Coaxial Aperture Proxim antenna.
