4G Antenna Indoor PCB Antenna Applications
Mobile phone built-in antenna classification
1. PIFA Picofarad Antenna
A. The radiator area of the antenna structure is 550～600mm2, and the distance (height) from the TOP surface of the PCB mainboard is 6～7mm.
The antenna and the mainboard have two feed points, one is the antenna module output, and the other is the RF ground. The location of the antenna is at the top of the phone.
If the PIFA pico-fat antenna is designed according to the requirements of the environmental structure, the electrical performance is quite superior, including the SAR index, it is the first choice for the built-in antenna.
It is suitable for mobile phone products with a certain thickness, folding, sliding cover, screwing cover, and bar machines.
B. There is a complete floor in the projection area of the mainboard antenna, and no components should be arranged on the antenna side, especially components with large metal structures such as motors, SPEAKER, RECEIVER, FPC cables, LDOs, and low-frequency drive components.
They have a great negative impact on the electrical performance of the antenna.
C. The feed position and spacing of the antenna are generally recommended to be designed at the top left or top right; the spacing is between 4 and 5 mm.
2. Several structural methods of PIFA antenna
A. Bracket
The antenna consists of a plastic bracket and a metal sheet (radiator). The metal sheet and the plastic bracket are fixed by hot melt.
ABS or PC materials are commonly used for plastics, and beryllium copper, phosphor copper, and stainless steel sheets are commonly used for metals. FPC can also be used, but two PINs need to be added to the mainboard, and the cost of these two items is slightly higher.
B. Attached
Attach the metal sheet (radiator) directly to the back shell of the phone. The fixing method generally uses a hot melt structure. Adhesive methods are also used, but because the structure is not very stable, it is rarely used. The same is true for FPC.
3. MONOPOLE (MLK) monopole antenna
A. Antenna structure
The area of the radiator is 300～350mm2, and the distance (height) from the TOP surface of the PCB is 3～4mm. The relative distance between the antenna radiator and the PCB should be greater than 2mm. The antenna and the mainboard have only one feed point, which is the output of the module.
The location of the antenna is on the top or bottom of the phone.
If the MONOPOLE monopole antenna is designed according to the requirements, the electrical performance can reach a higher level. The disadvantage is that the SAR is slightly higher. It is not suitable for folding and sliding cover machines and has advantages in bar machines and ultra-thin bar machines.
B. Motherboard
The antenna projection area must not have a floor or PCB and should not arrange components with large metal structures such as motors, speakers, receivers, etc. Since the electrical performance of monopole antennas is particularly sensitive to metals, it can not even be achieved.
C. The location of the feed point of the antenna
It is different from the PIFA method. It is generally recommended to design on the four corners of the antenna.
4. Several structural methods of MONOPOLE monopole antenna
A. Same as PIFA antenna, with bracket type and attached type.
B. The radiator of the PCB-type MONOPOLE monopole antenna adopts the PCB board, and the feed with the mainboard has reed and PIN methods and is thermally fused on the plastic bracket. It can also be installed with a positioning hook on the casing.
C. The special structure antenna is designed on the top elevation (thickness) of the mobile phone and is formed by metal wire.
