摘要： This disclosure presents an antenna device including one or more arrays of radiating elements, wherein each array may be an end-fire array. The antenna device comprises particularly an array of N radiating elements (N > 1) arranged on a common axis. Each radiating element is configured to radiate a radio wave in response to a RF signal fed to the respective radiating element. A reflector is arranged on the common axis to reflect the N radio waves into a main radiating direction. The antenna device also comprises a feed structure to feed a RF signal to each radiating element. The RF signal at each radiating element has a respective phase difference relative to the RF signal at a first radiating element. The feed structure comprises one or more phase shifters, for one or more or all radiating elements, to set the phase difference of the RF signal at the respective radiating element.

摘要： A new category of antennas for mobile communications devices specifically designed for reducing the emitted power dissipated within biological tissues of the user of the device. The antenna, operating in a single or a multiple band of frequencies, is constituted by an array of radiating elements fed with relative powers and phases specifically chosen to yield, through superposition effects, a small electric field in a region close to the antenna and normally occupied by biological tissues of the user of the device and thus reducing the SAR within said region.

摘要： A phased antenna array (1) comprises a plurality of antennas (10) with a quarter wavelength transformer (12) and a phase delay element (14) inserted between adjacent antennas. Preferably, the antennas (10) are dipoles and have their lengths selected so that their input impedances become entirely real in the array environment. The quarter wavelength transformers (12) are connected to the input of the dipoles (10) and are designed to achieve a desired division of current among the antennas (10). The phase delay elements (14) introduce phase delays to steer the main beam of the antenna array (1) to a desired beam angle. The array may further comprise more than one column of antennas with the current distribution and the phasing between the columns being adjustable with a transformer. The array is formed on both sides of a flexible substrate and separated from a ground plane by a quarter wavelength.

摘要： A multi-band generalized antenna architecture using two or more types of antenna element is presented. Linear arrays of a first type of antenna element are used for one or more frequencies while a second antenna element type is used for other frequencies. The second type of antenna element is located between the linear arrays of the first antenna element type. The second antenna element type may be arranged in a staggered configuration or they may be arranged as linear arrays as well. The first type of antenna element may be a patch antenna element while the second type of antenna element may be a dipole antenna element. The patch antenna element may be used for high band frequencies while the dipole antenna element may be used in low band frequencies. The spacing in vertical direction is not equal to minimize the effect of arrays on each other.
