Advantages and disadvantages of microstrip antenna

Microstrip antenna is one of the most popular types of printed antenna, it plays a very significant role in today's world of wireless communication technology. This antenna is very simple in construction using conventional fabrication techniques.

So if you want to learn some different you are the right place for reading so keep reading for a few minutes for the right information regarding microstrip antenna. Let us have a deep insight into the benefits and disadvantages of a microstrip antenna.

Advantages of microstrip antenna:

  • Low fabrication cost, hence can be manufactured in large quantities.
  • Capable of dual and triple frequency operations.
  • Easily integrated with microwave integrated circuit.
  • This antenna has a smaller size and hence will provide small size and devices.
  • Low cost.
  • High performance
  • Light in weight and low volume.
  • Low mass.
  • Support both linear as well as circular polarization.
    They operate at microwave frequencies where the traditional antenna is not feasible to be designed.
  • Rectangular, triangular, square is the different shape of microstrip patches so easily etched.
  • As the path antennas are fed along the centerline to symmetry, it minimized excitation of other undesired modes.
  • Microstrip antenna is easy to integrate them with MICs and MMICs.
  • They are robust when mounted on a rigid surface of the devices.
  • Feedline and matching network can be simultaneous with the antenna structure.

Disadvantages of microstrip antenna:

  • It offers a lower gain.
  • Narrow bandwidth associated with a tolerance problem.
  • It excitation of surface waves.
  • Large ohmic losses in feed structure of arrays.
  • Most of the microstrip antenna radiates into half-space.
  • It has a lower power handling capability.
  • Low power handling capacity.
  • Extraneous radiation from feeds and junctions.
  • It has a higher level of cross-polarization radiation.
  • It offers low efficiency due to dielectric losses as well as conductor losses.
  • It has inherently lower impedance bandwidth.
  • This type of structure radiates from feeds and other junction points.
