MICRO STRIP PATCH ANTENNA
[attachment=67161]
INTRODUCTION
The IEEE definition of an antenna as given by Stutzman and Thiele is, “That part of a transmitting or receiving system that is designed to radiate or receive electromagnetic waves”.
MICRO STRIP PATCH ANTENNA:-
In its most basic form, a Microstrip patch antenna consists of a radiating patch on one side of a dielectric substrate which has a ground plane on the other side as shown in Figure 3.1. The patch is generally made of conducting material such as copper or gold and can take any possible shape. The radiating patch and the feed lines are usually photo etched on the dielectric substrate.
APPLICATIONS
• For embedded antennas in handheld wireless devices such as cellular phones, pagers etc.
• The telemetry and communication antennas on missiles need slot microstrip patch antennas.
• Used successfully in satellite communication
ADVANTAGES
• Low profile planar configuration which can be easily made conformal to host surface.
• Low fabrication cost, hence can be manufactured in large quantities.
• Supports both, linear as well as circular polarization.
• Can be easily integrated with microwave integrated circuits (MICs).
• Capable of dual and triple frequency operations.
• Mechanically robust when mounted on rigid surfaces
