缝隙天线及电子设备制造技术

本发明专利技术实施例提供了一种缝隙天线及电子设备，涉及天线领域，所述缝隙天线包括：具有缝隙的印刷电路板、第一电容、射频信号源、传输线以及地线；印刷电路板接地；缝隙一端开口，另一端闭合；第一电容和地线设置于印刷电路板上，第一电容位于缝隙开口端，且设置于缝隙的一侧；第一电容和射频信号源通过传输线相连，且射频信号源连接传输线和地线；射频信号源，用于激发馈入信号，并将馈入信号经过第一电容馈入缝隙开口端。本发明专利技术通过一电容将信号馈入缝隙开口端，只需要选用固定电容值的电容即可以实现阻抗匹配，对制作工艺的要求较低，同时，电容的体积较小，能够减小缝隙天线的占用空间。

Slot antenna and electronic equipment

The embodiment of the invention provides a slot antenna and electronic device, relates to the antenna field, the slot antenna includes a printed circuit board, with the first gap capacitance, frequency source, transmission line and ground wire; printed circuit board ground; the gap is open at one end, the other end is closed; the first capacitor and the ground wire is arranged on the printed the circuit board, a first capacitor located at the slit opening end side and arranged in the slot; the first capacitor and the RF signal source is connected through a transmission line, and the RF signal source is connected with the transmission line and the ground wire; RF signal source for excitation signal and the signal feed, feed through the open end of the first capacitor fed slot. The present invention through a capacitor signal feed slot opening end, only need to use the fixed capacitor capacitance value which can realize the impedance matching, on the production process requirements are low, at the same time, smaller occupied space can reduce the capacitance of the slot antenna.
