4.6 Antenna Design

1. Antenna Requirements

Antenna efficiency is the ratio of antenna input power to radiation power. Because of the return loss,

material loss, coupling loss and radiation power of the antenna are lower than the input power, it is

recommended that the antenna should be more than 40% (-4 dB).

2. S11 or VSWR

S11 shows the matching degree of 50 Ω impedance of the antenna, which affects the antenna

efficiency to a certain extent. The VSWR test can be used to measure this index. S11 < - 10 dB is

recommended.

3. Polarization

Polarization is the rotation direction of the electric field in the maximum radiation direction of the

antenna.

Linear polarization is recommended.

4. Radiation Pattern

Radiation pattern refers to the intensity of electromagnetic field in all directions of far-field. Half wave

dipole antenna is the most suitable terminal antenna. If it is a built-in antenna, it is recommended to

use PIFA antenna or IFA antenna:

Antenna area: 6 mm (height) × 10 mm (width) × 100 mm (length).

Antenna radiation direction: Omni _ Directional.

5. Gain and Directivity

The directivity of antenna refers to the electromagnetic field strength of electromagnetic wave in all

directions. Gain is the combination of antenna efficiency and antenna directivity.

The recommended antenna gain is ≤ 2.5 dBi

6. Interference

In addition to the antenna performance, other interference on the PCB board will also affect the

module performance. In order to ensure the high performance of the module, the interference must

be well controlled. Suggestions: for example, LCD, CP, FPC wiring, audio circuit, power supply part

should be as far away from the antenna as possible, and the corresponding isolation and shielding,
