Consider the following statements associated with microstrip patch antenna: 1. The microstrip patch behaves more like a leaky cavity rather than like a radiator and this is not a highly efficient antenna. 2. They can be adapted for radiation of circularly polarized waves. Which of the above statements is/are correct?

The microstrip patch behaves more like a leaky cavity rather than like a radiator and this is not a highly efficient antenna. 2. They can be adapted for radiation of circularly polarized waves. Which of the above statements is/are correct? Correct Answer 1 only 

Micro-strip patch antenna:

  • It is designed to operate on microwave frequencies.
  • It can be directly built on a printed circuit board.
  • Its radiation intensity is low as a small resonator cavity.
  • It is not very efficient because it has a low profile, easily fabricated, and low cost
  • It is a linearly polarized antenna.
  • A patch antenna array is required for a larger gain.
  • The photolithography technique is used during the fabrication of a microstrip patch antenna.
