What are the applications of patch antenna?

The patch antenna is mainly practical at microwave frequencies, at which wavelengths are short enough that the patches are conveniently small. It is widely used in portable wireless devices because of the ease of fabricating it on printed circuit boards.

What is microstrip patch antenna and its advantage disadvantage?

Drawbacks or disadvantages of Microstrip Antenna ➨It offers lower gain. ➨It has higher level of cross polarization radiation. ➨It has lower power handling capability. ➨It has inherently lower impedance bandwidth. ➨The microstrip antenna structure radiates from feeds and other junction points.

Which of the following is the application of microstrip antenna in telemedicine industry?

Which of the following is the application of Microstrip antenna in a telemedicine industry? Explanation: A 2.4 GHz Wearable Microstrip antenna is used for the Wireless Body Area Network. Detection of moving targets comes under radar application.

What are the features of microstrip antenna?

A Microstrip Antenna in its simplest form consists of a radiating patch on one side of Dielectric substrate and a ground plane on the other side. Most common shapes are rectangular and circular. However, other Shapes such as the square, mendered, triangular, semicircular and annular ring Shapes are also used.

Which antennas are popular as patch antennas especially adopted for space craft applications?

Which kind of polarization is provided by helical antennas?

A helical antenna is an antenna consisting of one or more conducting wires wound in the form of a helix. The helical antenna is used for satellite communication due to its high directivity and circular polarization of the transmitted EM waves.

In which of the following type of antenna a patch is created during fabrication *?

Microstrip antenna patch
In which of the following type of antenna a patch is created during fabrication? Explanation: In Microstrip antenna patch is created on the dielectric substrate using photo-etching.

What are the applications of microstrip antennas?

Mobile and satellite communication application: Mobile communication requires small, low-cost, low profile antennas. Microstrip patch antenna meets all requirements and various types of microstrip antennas have been designed for use in mobile communication systems.

How does a patch antenna work?

Working of Patch Antenna A microstrip or patch antenna operates in a way that when current though a feed line reaches the strip of the antenna, then electromagnetic waves are generated. The waves from the patch start getting radiated from the width side.

How is hemispherical antenna coverage provided?

Generally, hemispherical coverage is provided by a patch antenna at an angle of 30⁰ to 180⁰ at width from the mount. The figure below represents the radiation pattern of the microstrip antenna: The patch of the antenna must be a very thin conductive region, t<<λ0 (: λ 0 free space wavelength).

What is a patch or strip?

Basically the patch or strip and the feed lines are photo-etched on the surface of the substrate. As we have already discussed that patches can be formed in multiple shapes, however, due to easy fabrication rectangular, circular or square-shaped patches are generally used.
