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.

A system and method for continuous glucose monitoring (CGM) of blood in a blood vessel of a patient using a non-invasive sensor composed of a patch antenna operating in the Industrial, Scientific and Medical (ISM) Radio band (5.725 GHz-5.875 GHz). The device determines the blood glucose concentration of the blood in the blood vessel based on the measured shift of the resonant frequency of the non-invasive antenna patch sensor. A radio frequency (RF) synthesizer is used to drive the patch antenna with a fraction of its output coupled to both the antenna and receiver through a directional coupler. In this approach both the transmitted (FWD) and received (REV) power are processed, by demodulating logarithmic amplifiers, which convert the RF signals to corresponding voltages for downstream processing. The resulting voltages are then fed into a microcontroller and the measured shift in resonant frequency is converted to a real-time glucose concentration.
