Abstract: Disclosed herein is a built-in type antenna assembly of a wireless communication terminal. The antenna assembly comprises a board, a case mounted on the board and having at least one disposing part formed through the case such that a portion of an upper surface of the board is exposed through the disposing part, an antenna member mounted on the case to radiate electrical signals from the board to the outside while receiving external signals, and a resilient part disposed within the disposing part to provide resilient force for maintaining contacts between an upper end thereof and the antenna member and between a lower end thereof and the board to electrically connect the board and the antenna member. The antenna assembly has a constant path of electrical signals and electric waves, providing uniform performance, and is reduced in the number of components, thereby reducing manufacturing costs while enhancing assembly efficiency.

Abstract: Disclosed is a built-in antenna module of a wireless communication terminal. The built-in antenna module includes at least one base mounted on the upper surface of a substrate of a main body of the terminal; a radiator line formed in a designated pattern on the external surface of the base according to antenna characteristics; and at least one feeding terminal electrically connecting the radiator line and the substrate. The built-in antenna module simplifies a process for manufacturing the module, reduces production costs, and rapidly copes with the design change of an antenna.

Abstract: A housing having lead frames which are protruded to contact and to resiliently support a piezoelectric transformer and a method of manufacturing the housing is disclosed. The housing has an upper housing part having at least two first lead frames protruded to resiliently contact input and output portions of an upper surface of the piezoelectric transformer, and a lower housing part having at least two second lead frames protruded to resiliently come into contact with the input and output portions of a lower surface of the piezoelectric transformer. The first and second lead frames are outwardly extended from the upper and lower housing parts, and the piezoelectric transformer is received in the upper and lower housing parts such that the piezoelectric transformer is resiliently supported by the first and second lead frames.
