How does the Microstrip antenna work?
Microstrip antennas are the low-profile antennas. A metal patch mounted on a ground level with a dielectric material in-between constitutes a Microstrip or Patch Antenna. These are very low size antennas having low radiation. The patch antennas are popular for low profile applications at frequencies above 100MHz.Construction and workingThe microstrip consists of a very thin metallic strip placed on a ground plane with a dielectric material in-between. The radiating element and feed lines are placed by the process of photo-etching on the dielectric material. Usually, the patch or microstrip is chosen to be square, circular or rectangular in shape for ...
Read MoreWhat would happen if Earth started to rotate in the opposite direction?
Earth rotates around its own axis which is tilted at 23.5 degrees, from the plane of its orbit around the sun, in the eastward direction. It takes almost 24 hours to complete one rotation. The Earth rotates at a speed of 460 m/s, that is approximately 1650 km/hr at the equator. The angular velocity of the Earth decreases as we keep moving toward the poles.The Earth's rotational speed is slowing down with time. According to atomic clocks, the present day is 1.7 milliseconds slower than a century ago. It is not a big issue as it will take more than ...

Read MoreWhat is Flaring and what are the different types of Horn antennas?
To improve the radiation efficiency and directivity of the beam, the waveguide should be provided with an extended aperture so as to make the abrupt discontinuity of the wave into a gradual transformation, so that all the energy in the forward direction gets radiated. This can be termed as Flaring. Flaring is done to provide greater directivity and narrower beam width. The types of horn antennas depend on how they are flared.Sectoral HornThis type of horn antenna, flares out in only in one direction.
