Techopedia Explains Patch Antenna

A patch antenna has a curved path of coverage; hanging on a wall, it can spread to a width of 30 to 180 degrees. This type of antenna is usually lightweight and can be easily hung on walls, encased in white or black plastic to make it inconspicuous to the observer. Moreover, the plastic casing protects the assembly from damage and also makes it easy to mount. A patch antenna is easy to make and can be customized and modified without much of an effort. It is commonly manufactured using the same materials and process for constructing printed circuit boards on a dielectric material.
