Problems solved by technology

When the Bluetooth device is working, because the RF frequency jumps in 79 sub-bands, there is a certain deviation between the RF frequency and the antenna resonant frequency, which will cause the sensitivity of the Bluetooth antenna equipment to be low, and because of its large frequency deviation, the antenna cannot be very good. Transmit or receive electromagnetic wave energy

Abstract

The embodiment of the invention discloses a Bluetooth antenna design method and related equipment, which increase the sensitivity of transmitting and receiving electromagnetic waves by an antenna in Bluetooth equipment. The method of the embodiment of the invention comprises the following steps: determining the antenna length of a first element antenna and the antenna length of a second element antenna according to the center frequency of the first element antenna and the center frequency of the second element antenna; determining an input impedance of the first element array according to the antenna length of the first element antenna and the center frequency of the first element antenna; determining an input impedance of the second element array according to the antenna length of the second element antenna and the center frequency of the second element antenna; determining the length of a transmission line in a target decoupling loop according to the input impedance of the first element array and the input impedance of the second element array; and determining a target array antenna according to the antenna length of the first element array, the antenna length of the second element array, the length of the transmission line in the target decoupling loop and shunt admittance.

Description

technical field [0001] The invention relates to the communication field, in particular to a design method of a bluetooth antenna and related equipment. Background technique [0002] Bluetooth is a radio technology that supports short-distance communication (generally within 10m) of terminal devices, and can exchange information wirelessly between devices. Its operating frequency is the 2.4GHz ISM (Industrial Scientific Medical) frequency band. Due to its powerful functions, low power consumption, low cost, and license-free working frequency band, it has been widely used in mobile communication devices such as mobile phones and portable computers. Bluetooth converts the working frequency band between 2.4G and 2.483GHz into 79 sub-frequency bands, and each frequency band occupies 1M bandwidth. The RF frequency used for frequency hopping is randomly selected in the 79 sub-frequency bands in the form of frequency hopping during transmission and reception. Before data transmiss...
