2. Patch antenna “Microstrip” or “Patch”:

It is the antenna that is formed by drilling a
piece of conductive material on an insulating
surface, and the insulating material is installed
on a ground level, where the ground level
supports the entire structure, and also
excitation is provided for the antenna using
feed lines connected through the patch.

5. Construction and working
The 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 the ease of
analysis and fabrication.

6. Microstrip Antenna Advantages:
• The antenna is small in size.
• It provides an easy manufacturing process.
• Because of the small size, there is ease in
installation.
• Provides easy integration with other devices.
• It can perform double and triple frequency operations.
• Antenna arrays can be built easily.
• It provides a high degree of durability on hard surfaces.

7. Microstrip Antenna Disadvantages:
•The antenna efficiency is low.
•These antennas exhibit highly sensitive behavior to
environmental factors.
• These offer low processing power, low gain and
narrow bandwidth.
• More susceptible to false feeding radiation.
• There are more dielectric and conductive losses in
"microstrip" antennas.

8. Microstrip Antenna Applications:

• The low profile structure of the microstrip antennas
provides wide use in wireless communications, which
is why these antennas show compatibility towards
portable devices, such as pagers and mobile phones.
• Due to the thin structure of these antennas, they are
used as communication antennas on missiles.

9. • Satellite communications and microwave
applications also benefit from the microstrip
antenna due to its small size.
• Used in GPS, one of the most important
advantages of modulator antennas is that it
provides easy tracking of vehicles and marines.
• They are also used in applications in phased
array radars, where they can handle bandwidth
tolerances up to a certain percentage.
