Abstract: An integrated module of antenna and connector has an insulative housing receiving a plurality of conductive terminals therein, a metal shell shielding the insulative housing, and a coupling device assembled on the metal shell. The metal shell is grounded and defines a slot with a particular shape. A feed-in terminal is provided on a side of the slot and includes a soldering portion and a contact portion. The soldering portion of the feed-in terminal connects with a circuit board. The coupling device contacts the contact portion of the feed-in terminal, feeding in high-frequency voltage which forms voltage difference relative to a plane of the slot. A resonant electromagnetic field is produced in the slot for working as an antenna for electromagnetic wave radiation. Thus, functions of an antenna and a connector are combined, reducing the occupied space and decreasing the cost.

Abstract: A multiband frequency selective filter is assembled on a housing or an antenna module of a small portable device. The multiband frequency selective filter comprises at least two overlapped substrates. Each substrate includes a dielectric base and a conductive layer. The conductive layers respectively form unit cells. The unit cells are arrayed periodically or non-periodically. Appropriate shape and arrangement of the unit cells and overlapping of the substrates, forms a three-dimensional resonant array of inductance and capacitance in direction of a plane and height of the unit cells, thereby evidently lessening resonant wave length of electromagnetic wave and achieving miniature of unit cells of FSS.
