A patch antenna is a type of radio antenna 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 ground plane. They are the original type of microstrip antenna described by Howell in 1972; the two metal sheets together form a resonant piece of microstrip transmission line with a length of approximately one-half wavelength 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 resonant, 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 microwave 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 printed circuit boards. Multiple patch antennas on the same substrate (see image) called microstrip antennas, can be used to make high gain array antennas, and phased arrays in which the beam can be electronically steered.

Switchable patch antenna
ActiveUS12362472B2Antenna supports/mountingsRadiating elements structural formsElectrical conductorMechanical engineering
A switchable patch antenna comprises a planar conductor having an aperture (hole) formed in the middle of the planar conductor. Radiation of a sinusoidal signal is controlled by comparison of separate impedance values for two components that have separate impedance values. Each of the two components have one end coupled together at the terminal positioned at a center of the aperture and their other ends separately coupled to opposing edges of the aperture. A sinusoidal signal source is also coupled to the terminal positioned at the aperture's center. Further, when the impedance values of both components are substantially equivalent, radiation by the antenna of the provided signal and / or mutual coupling of other signals is disabled. Also, when an impedance value of one of the two components is substantially greater than the other impedance value of the other component, the provided signal is radiated and / or mutual coupling is enabled.
