Wire antennas and various antennas in RF circuits

The wire antenna is a classic antenna of a quarter wave long conductor. They are fixed on the PCB but rises from the PCB plane and protrude to the space on the ground plane. Since they are exposed to the air as the 3D antenna, they have excellent radio frequency performance. They have the best radiation range and have the most comprehensive Sexual radiation pattern. For BLE applications that require small size, they are not preferred because they require large space and vertical height. However, if space is unlimited, in terms of radio frequency range, direction and radiation pattern, they can be used as optimal antennas. Typically, applications such as intelligent home controllers inserted into the wall can use this type of antenna. The shape and size of the wire need to be optimized for a specific industrial design (ID). The wire can be bent according to the outer casing. Special attention should be paid to the manufacture of the wire antenna, as the wire antenna can have different shapes depending on the shape of the housing. Wire antenna layout Wire antennas are best RF performance. Compared to other antennas, they have the best antenna efficiency and directionality.
