A [microstrip] antenna is a narrowband, wide-beam antenna fabricated by etching the antenna element pattern in metal trace bonded to an insulating dielectric substrate [...]
A microstrip antenna is a type of antenna that is constructed on a thin substrate such as a printed circuit board using a metallic strip or patch. It is commonly used in wireless communication devices due to its low cost, compact size, and ease of integration with other electronic components.
A microstrip antenna works by transmitting and receiving electromagnetic waves through the metallic strip or patch on its substrate. The antenna is fed by a transmission line, and the metallic element acts as a resonator to radiate or receive electromagnetic energy in the desired direction. The size and shape of the metallic element determine the frequency and radiation pattern of the antenna.
The main advantage of a low profile microstrip antenna is its compact size. Due to its flat and thin design, it can easily be integrated into electronic devices, making them more portable and space-efficient. Low profile antennas are also less obtrusive and can be mounted in tight spaces, making them ideal for use in small devices such as smartphones and GPS systems.
One limitation of a low profile microstrip antenna is its narrow bandwidth. The size and shape of the metallic element restrict the range of frequencies that the antenna can transmit or receive. This can lead to reduced performance in terms of signal strength and range. Additionally, low profile antennas may be more susceptible to interference from nearby electronic components, which can affect their performance.
To optimize the performance of a low profile microstrip antenna, the size and shape of the metallic element can be adjusted to match the desired frequency and radiation pattern. Additionally, adding a ground plane or using a stacked configuration can improve the antenna's bandwidth and radiation efficiency. Proper placement and orientation of the antenna can also help reduce interference and improve signal strength.
