Embodiment Construction

[0043] In the below described embodiments of the invention, the same reference numerals will be used for the same features in the different drawings.

[0044] figure 1 An antenna device 100 according to an embodiment of the present invention is schematically shown. The antenna arrangement 100 comprises an antenna array 102 comprising a first antenna element 104a with a first feed point 106a and a second antenna element 104b with a second feed point 106b. The first antenna element 104a and the second antenna element 104b have different physical dimensions, such as figure 1 Their different lengths are shown in . The lengths La, Lb of the first antenna element 104a and the second antenna element 104b are both in the interval 5mm to 100mm, and preferably in the interval 10mm to 50mm. The different physical dimensions of the first antenna element 104a and the second antenna element 104b mean that they have different electromagnetic resonance frequencies. The antenna arrangement...

Abstract

An antenna arrangement (100) is described. The antenna arrangement (100) comprises an antenna array (102) comprising a first antenna element (104a) comprising a first feed point (106a) and a second antenna element (104b) comprising a second feed point (106b) ). The antenna arrangement (100) further comprises signal processing means (108) for receiving an input signal (Sin), obtaining a first composite weight (w 1 ), get the second composite weight (w 2 ), based on the input signal (Sin) and the first composite weight (w 1 ) to generate the first feed signal (a 1 ), based on the input signal (Sin) and the second composite weight (w 2 ) to generate a second feed signal (a 2 ), the first feed signal (a 1 ) to the first feed point (106a) and the second feed signal (a 2 ) is provided to the second feed point (106b) in order to control the frequency characteristics of the antenna array (102). A method for such an antenna arrangement (100) is also described.

Description

technical field [0001] The invention relates to an antenna arrangement and a method for controlling such an antenna arrangement. Background technique [0002] With the continuous development of communication technology, antennas continue to have more and more stringent requirements on performance. In particular, the mobile industry continues to develop new technologies to increase data rates for mobile devices. This requires the use of new frequencies and wider bandwidths. This means that the antennas have to work at different frequencies. Achieving efficient operation on all required frequencies is challenging, especially when there is limited space available for antennas in mobile devices. [0003] The mobile device's antenna does not have to operate on all operating frequencies at the same time, which makes it possible to circumvent bandwidth requirements through frequency reconfigurability. Only the desired frequency bands are covered at a time, rather than all opera...
