Fairview Microwave's Microstrip Patch Antenna Calculator determines the length and width (in millimeters) of a rectangular patch antenna.
Microstrip Patch Antennas (or simply patch antenna) are increasingly useful because the antenna is printed directly onto a circuit board. Additional benefits of patch antennas is that they are easily fabricated making them cost effective. Their low profile design, often square or rectangular, allows them to be mounted to flat surfaces. Fairview Microwave carries a variety of panel and patch antennas which can be seen here.
**Note: All of our calculators allow SI prefix input. For example, if you wish to input "25000000", just type "25M" instead. See the quick-reference table below for all compatible SI prefixes.
