Patch Antenna Ground Plane Design
A 2.4 GHz patch antenna A patch antenna (also known as a rectangular microstrip antenna) is a type of radio with a low profile, which can be mounted on a flat surface. It consists of a flat rectangular sheet or 'patch' of metal, mounted over a larger sheet of metal called a. They are the original type of described by Howell in 1972; the two metal sheets together form a resonant piece of with a length of approximately one-half of the radio waves. The radiation mechanism arises from discontinuities at each truncated edge of the microstrip transmission line. The radiation at the edges causes the antenna to act slightly larger electrically than its physical dimensions, so in order for the antenna to be, a length of microstrip transmission line slightly shorter than one-half the wavelength at the frequency is used. The patch antenna is mainly practical at frequencies, at which wavelengths are short enough that the patches are conveniently small. It is widely used in portable wireless devices because of the ease of fabricating it on.
Multiple patch antennas on the same substrate (see image) called, can be used to make, and in which the beam can be electronically steered. A variant of the patch antenna commonly used in mobile phones is the shorted patch antenna, or (PIFA). In this antenna, one corner of the patch (or sometimes one edge) is grounded with a ground pin. This variant has better matching than the standard patch.

Another variant of patch antenna with the partially etched ground plane, also known as printed monopole antenna, is a very versatile antenna for dual-band operations. References.
