The refrigerator door suddenly blew up.

Yesterday (February 28), Mr. Chen, owner of Block B of Wuchang Fruit Lake Plaza, reported that after a year and a half of the refrigerator, the door suddenly burst, and the after-sales service point was not guaranteed. The refrigerator was bought by Mr. Chen in a large appliance store in Zhongbei Road, Wuchang in July 2009. It cost 2,800 yuan. On the 25th of this month, Mr. Chen and his family are

An internal active GPS Patch Antenna with cable is used in most mobile devices today that require high signal strength in a small form factor. It is the highest performing solution of all antenna types.

Usually consisting of a specially formulated dielectric ceramic, a trace is printed on the substrate to get the desired right hand circularly polarized Patch Antenna topology. The patch is mounted on a PCB; underneath the PCB is the Low Noise Amplifier (LNA) which amplifies the GPS signal before being transmitted through the coaxial cable and connector to the receiver.

This design application note is intended to help the antenna integrator understand the relevant parameters affecting the antenna performance.
Yetnorson recommends that the integrator strictly follow the guidelines in this application note. Upon your device prototype completion, Yetnorson can provide further optimization by offering custom tuning and testing services for the antenna in your device.
