Introduction to Microstrip Antennas A microstrip antenna is a resonant radiator, whose radiation field is produced by the electromagnetic field of mutual-motivation between the upper radiation patch edges of microstrip antenna and the grounding plate, and constantly radiates out electromagnetic waves through the gap between them [ 16 , 17 ].

Microstrip antenna: the most common printed antenna

Many times omnidirectional antenna is used in mobile phones.

There are different kinds of antennae like planar inverted-F antenna, folded inverted conformal antenna and mono pole. Also retractable whip antenna is commonly used in handsets. The phone is subdivided into roughly 60 components, each consisting of hundreds or even thousands of individual facets.

The internal structure of a mobile handset is shown in Fig. In the treatment of malignant tumours , microwave energy is said to be the most effective way of inducing hyperthermia. The radiator to be used for this purpose should be light-weight, easy to handle and rugged. Only a patch radiator fulfils these requirements.


The initial designs of microstrip radiators for inducing hyperthermia were based on printed dipoles and annular rings that were designed on S-band GHz. Later on the design was based on a circular microstrip disk at L-band GHz. Two coupled microstrip lines with a flexible separation are used to measure temperature inside the human body. There are some applications at present where antennae are used to continuously monitor biometric data of the human body. In order to do this, they need to be so close to the human body all the time that they can continuously monitor the biometric data and send the information to the outside world.

If the antenna is hard, it cannot be kept always attached with the human body. An antenna made of textile material will not harm the human body and can be worn for extended periods. Wearable antennae will find use in healthcare, recreation, fire-fighting, etc. Textile materials are increasingly being used for development of flexible wearable systems due to the recent miniaturisation of wireless devices. For flexible antennae, textile materials form interesting substrates, because fabric antennae can be easily integrated into clothes. In this special type of patch antenna, the radiating patch and the ground plane are made up of conductive textile material.

The substrate too is a textile material with specific dielectric constant. As everything is made up of textile material, it is called textile antenna. Textile antennae are still under testing, so they are rarely in focus. Patil is professor and head, and Prof.

Sir your information is very useful to us. Is it possible to explain where the ground plane reference plane should be located, relative to the antenna and why? I am trying to decide my topic for phd. Here I got little info.
