Abstract: A connector assembly has a plug connector and a socket connector. The plug connector has a first insulative housing and at least one row of first terminals. The first terminals are mounted on the first insulative housing and each terminal has an inside contacting portion and an interference portion. The socket connector has a second insulative housing and at least one row of second terminals corresponding respectively to the at least one row of the first terminals. The second terminals are selectively engaged and respectively with the first terminals and each second terminal has an inner contacting portion and a shoulder portion. The inner contacting portion selectively contacts the inside contacting portion of one first terminal. The shoulder portion is selectively engaged with the interference portion of one first terminal and prevents the first terminal from disengaging inadvertently from the second terminal.

Abstract: A multi-band antenna with the broadband function is based upon a planar inverted-F antenna with two conductive arms and a ground. The two conductive arms extend from the ground near the two opposite ends of the ground. Two radiation plates of the two conductive arms extend toward each other. The multi-band antenna has a sufficient large band at high frequencies. Since the conductive arms are disposed close to the two ends of the ground, operations of bending the two conductive arms or soldering a feed wires are simpler and have a higher yield.

Abstract: A coupled multi-band antenna with the broadband function includes a coupled radiator, a feed wire, a first radiating extension, and a second radiating extension. The coupled radiator has a microwave substrate, a coupled metal element, a first radiating element, a second radiating element, and a connecting portion. The coupled metal element is connected to the positive terminal of the feed wire, and the second radiating element is connected to the negative terminal of the feed wire for the purposes of transmitting electrical signals and generating the multi-band operating modes of the antenna. By connecting the first and second radiating extensions to the coupled radiator, the surface current distribution and impedance variation of the antenna can be effectively adjusted to provide multi-band functions. The antenna utilizes the simple structure of coupled radiator to achieve multi-band operations and uses the radiating extensions to provide sufficient bandwidths.
