Introduction

Microstrip Patch Antenna

Microstrip antennas become very popular in 1970s.

Microstrip antennas are used in a moving device such that mobile, aircraft, satellite, missile.

Microstrip antennas are attractive due to their light weight, low profile and low cost.

Square, rectangular and circular are the most common shape for microstrip patch antenna.

IE3D BASICS

Since there are various softwares for the designing of the patch antenna such as HFSS, Sonnet Software, IE3D Simulation Software etc. but we are using IE3D simulation software as a platform for the designing of the antenna

IE3D - A simulation software (version 15.20)

Developed by Mentor Graphics formally known as Zeland Software

Used to design and verify antenna, MMIC, RFID, RFIC, IC

packaging, and other high-frequency design structures.

Feeding Techniques

Microstrip line

Coaxial probe feed

Aperture coupling

Proximity coupling

Result Viewing

We can view various results after the simulation task is completed.

Some of them are listed below:

Voltage Standing Wave Ratio (VSWR)

Gain vs. Frequency Graph

Return Loss

Directivity

Current Distribution

Our Aim

Our aim is to Design of Microstrip Patch Antenna for WLAN

Applications.

To achieve this we are:

Going Through Previous Researches

Analyzing previous results

Comparing those results to get optimized method for designing the

antenna.

These results of previous researches shows various methods and gives

various ideas for the enhancement of the gain and bandwidth of the

antenna.

Microstrip Patch Antenna Design Challenges

Many methods have been used to increasing the bandwidth of Microstrip antenna.

Such as:

By changing the shape of Antenna

By changing the Feeding Techniques

By changing dielectric constant

By using antenna array
