  • Microstrip Antenna - ANT-GSM-PATCH-1

Microstrip Antenna
A patch antenna, also known as a rectangular micro-strip antenna, is a type of radio antenna with a low key, which could be deployed on a flat surface. It contains a flat rectangular sheet or "patch" of metal, installed over a larger sheet of metal called ground. They are the prototype of microstrip antenna described by Howell in 1972.Combination of the two metal sheets forms a reverberant substance of micro-strip transmission line with a length of roughly one-half wavelength of the radio waves spectrum. The radiation mechanism generates from discontinuities at individual truncated edge of the micro-strip transmission line. The radiation at the edges makes the antenna to perform somewhat larger electrically than its physical dimensions. Therefore, in order to make the antenna reverberant, a length of microstrip transmission line somewhat shorter than one-half a wavelength at the frequency is used. A variety of the patch antenna commonly utilized in mobile phones is the shorted patch antenna, or planar inverted-F antenna (PIFA). In this antenna, one corner of the patch is grounded with a ground pin. This variance has better matching than the standard patch.
