#PATCH ANTENNA ARRAY CALCULATOR PATCH#

A particular dielectric ceramic substrate supports the antenna patch trace. GPS active patch antenna is the best performing type for mobile applications.This is the longer WiFi wavelength capable of penetrating walls. 2.4 GHz Patch antenna is tuned to receive and send transmissions in the 2.4 GHz band.Typically, these are relatively large in scale and pole mounted. A cellular patch antenna gives a higher directional gain, aiming at a cellular tower.Dual-band patch antennas operate on two frequencies (simultaneously or independently), usually 2.4GHz and 5GHz bands for WiFi and mobile phone applications.Linear patch antenna tends to be receiving antenna working with the linear whip antennae you find on remote control cars, boats, and model planes.

For example, a circular patch with two, three, or six slots cut into the shape to create additional radiating and receiving points puts many antennae in a small space.

The simple fabrication process results in experimental designs in producing arrays of antenna. Still, you can have circular, hexagonal, triangular, and other geometric shapes for the patch and the ground plane. The standard shape of a rectangular patch works effectively for most applications. The slot length is half the radio waves’ wavelength, and the bandwidth is narrow – around 1%. The shape of the antenna and the number of slots available dictate how a patch antenna performs. Small form patch antennas allow smaller devices and more exciting benefits from technology.Ī slot is the edge of the patch antenna that transmits and receives the radio signal. Patch antenna uses are increasing, and any application that involves communicating wirelessly uses antennas. Tracking people and animals for search and rescue or conservation through collecting information through satellite tags.Remote sensing for exploring soil moisture levels or the salinity of the sea using satellites or aircraft.Biological imaging – noninvasive microwave images can detect and visualize brain tumors along with other medical uses.Vehicle collision avoidance systems – a civilian use of electronic sensors to highlight hazards.Arrays of patch antenna create complex antenna useful for MIMO applications with the increased data flow.Radiofrequency identification (RFID) systems for logistics, healthcare, and manufacturing.Satellite communication for GPS and other applications uses patch antenna in the satellites and devices.Mobile systems – if you want to move it and communicate with it, a patch antenna is the answer.Digital broadcast and receiving of television and signals – for a campus or office-only channel.Military applications include guided missiles, radar, electronic sensing, and tracking people.You can find patch antennas in every field because they are easy to make and occupy a small amount of space. A WiFi patch antenna can only cover a small area like an office, or a shop floor compared to a more efficient antenna covering whole buildings or outdoor spaces. A patch antenna is inefficient at transforming the power supplied into EM radiation. Power reaches the antenna through a feed line, and the EM waves radiate from the antenna’s width edge. The shape of the metal patch influences the shape of the electromagnetic radiation field. The distance between the metal patch and the underlying ground plane sets the bandwidth of the radio frequencies the patch antenna can transmit and receive. The ground plane must extend beyond the patch’s edges by two or three times the board thickness to ensure that the microstrip antennas work as expected. The separation is necessary to create a resonating circuit. A substrate provides mechanical support for the antenna trace, and the right material enhances performance. Typically, by photoetching the patch onto a dielectric substrate. The metal ground and the metal patch are separated.
