1: Physical geometry of microstrip antenna Antenna is one of the critical components in any wireless communication system. The word ‘antenna’ is derived from Latin word ‘antemna.’ Since the first demonstration of wireless technology by Heinrich Hertz and its first application in practical radio communication by Guglielmo Marconi, the antenna has been a key building block in the construction of every wireless communication system. IEEE defines an antenna as “a part of a transmitting or receiving system that is designed to radiate or receive electromagnetic waves.” Classification Antennae could be broadly classified as wire antennae, aperture antennae, printed antennae, array antennae, reflector antennae and lens antennae. Wire antennae This is the basic type of an antenna, widely used on top of the buildings, automobiles, ships and spacecrafts. These antennae are made into different shapes such as a straight wire (dipole), loop and helix. 2: Typical radiation pattern of microstrip antenna Aperture antennae These antennae are in the form of a slot or aperture in a metal plate and commonly used at higher frequencies (3-30 GHz). Typical examples are slotted waveguide antennae and horn antennae.

These antennae are very useful for aircraft and spacecraft applications, because they can be conveniently flush mounted on the surface of the aircraft or spacecraft. In practice, these antennae are covered with a dielectric material to protect them from hazardous environmental conditions. Rapidshare Proposal Kit. Printed antennae By definition, a printed antenna is one that is fabricated using standard photolithography technique. The most common version of printed antenna is microstrip antenna, which consists of a metallic patch above a ground plane. Head First Javascript Pdf Not Scanned.

The shape and size of patch determine the frequency of operation of the antenna and its performance. These antennae are more popular because of their low cost and ease of fabrication, and easy integration with circuit components. Printed antennae are inexpensive to fabricate using modern printed circuit technology, and are conformal to planar and non-planar surfaces. These antennae can be easily mounted on the surface of aircrafts, spacecrafts, satellites, missiles and even on handheld mobile devices. Array antennae In an array antenna, several radiators separated from each other are geometrically arranged to give desired radiation characteristics that are not possible to achieve with a single independent radiating element.
