Embodiment Construction

[0024] The following detailed description describes exemplary embodiments and is not intended to be limited to the expressly disclosed combinations. Thus, unless otherwise stated, various features disclosed herein may be combined to form additional combinations not shown for the sake of brevity.

[0025] From Figure 6 It can be appreciated that an antenna system 101 that may be referred to as providing a Dual Fed Triple Inverted L Antenna (DF-TILA) is disclosed. The antenna system includes a circuit board 105, which may be an existing printed circuit board or any suitable structure of similar design (e.g., a laser direct structuring (LDS) structure having traces thereon) . The circuit board 105 includes a first side 106a and a second side 106b. Elements 110 arranged around circuit board 106 are configured for resonance. As shown in the figure, the element includes a first arm portion 111 , a second arm portion 112 and a third arm portion 113 . From this, it can be apprec...

Abstract

An antenna is disclosed where a third resonator is added to the resonating structure. Impedance bandwidth improvements can be obtained for both high and low bands, with only a small increase of the antenna volume. The low band bandwidth can be further enhanced by active switching of the low band feed.

Description

[0001] related application [0002] This application claims priority to US Provisional Patent Application 61 / 487,777, filed May 19, 2012, which is hereby incorporated by reference in its entirety. technical field [0003] The present application relates to the field of antennas, and more particularly to the field of antennas suitable for use in mobile devices. Background technique [0004] One known antenna concept is called a Dual Fed Dual Inverted L Antenna (DF-DILA, Dual Fed Dual Inverted L Antenna). The DF-DILA antenna concept is applied to the Motorola ZN5 mobile phone. To illustrate its principles, a simple reference model of the DF-DILA concept was developed and shown in figure 1 middle. The typical dimensions of the model are: Printed Wiring Board (PWB) 15 = 40 x 100 mm, cutback 40 x 3 mm below components, and the components are located 5 mm above the PWB. The element 20 includes a first arm portion 22 and a second arm portion 24 . A first feeder 16 is configure...
