Microstrip or patch antennas are becoming more useful because they can be printed directly onto a circuit board. Microstrip antennas are becoming widespread in the mobile phone market. The patch antennas are inexpensive, have a low profile and are easy to manufacture.
In telecommunications, a microstrip antenna (also known as a printed antenna) usually means an antenna made using microstrip techniques on a printed circuit board (PCB). They are mainly used in microwave frequencies. An individual microstrip antenna consists of a patch of metallic paper of various shapes (a patch antenna) on the surface of a PCB, with a ground plane of metal foil on the other side of the plate. Most microstrip antennas consist of multiple patches in a two-dimensional array. The antenna is usually connected to the transmitter or receiver through the microstrip transmission lines of the blade. The radio frequency current is applied (or on receiving antennas the received signal is produced) between the antenna and the ground plane. Microstrip antennas have become very popular in the last decades because of their thin flat profile that can be incorporated into the surfaces of consumer products, aircraft and missiles; its ease of manufacture using printed circuit techniques; the ease of integrating the antenna in the same plate with the rest of the circuit and the possibility of adding active devices such as integrated circuits of microwaves to the same antenna to make active antennas.
