技術說明

本發明係關於一種可調式LTE/WWAN天線裝置，其包括：一接地元件及一天線元件。天線元件係位於一介質基板上，其包括：一饋入金屬部，饋入金屬部之一端係一饋入端；一耦合接地金屬部，其一端係短路端，短路端係耦接至接地元件，耦合接地金屬部與饋入金屬部具有一耦合間距，經由耦合間距，耦合接地金屬部由饋入金屬部電磁耦合激發，產生至少一共振模態，增加該天線之操作頻寬；以及一可重組電路元件組，耦接於耦合接地金屬部之一第一輻射段及一第二輻射段之間，以選擇性地導通或不導通第一輻射段及第二輻射段，以使得天線元件操作於多重頻帶。 The invention is an adjustable-frequency-band antenna device comprising a ground element and an antenna element. The antenna element disposed on a dielectric substrate is constructed with three parts, including a feeding strip, a coupling strip and a reconfigurable-circuit element. One end of the feeding strip is a feeding port. The coupling strip extends from an edge of the ground plane to an open end. There exists a coupling gap between the feeding strip and the coupling strip. The reconfigurable-circuit element is connected between a first radiation segment and a second radiation segment of the coupling strip. The invented antenna element can be operated in different communication bands by switching the reconfigurable-circuit element such that the first and second radiation segments are or are not directly connected.
