Problems solved by technology

While this type of antenna element array arrangement has been employed and produced acceptable performance, some antenna parameters have limited deployment due to its large size and weight, which is based on the frequency of operation via the spacing between antenna elements to enforce
In existing arrangements, the required separation of dual-band antenna elements in the lower frequency band is Vs1+Vs2+Vs1>2λ (where the dimensions of Vs1 and Vs2 are related to the separation between the HAx axes), which limits the to the number of dual-band antenna elements on the reflector such that the forward gain in the low band is lower than would be possible

Embodiment Construction

[0021] Reference is made to the accompanying drawings, which assist in illustrating the various salient features of the present disclosure. Due to the multiple locations and uses of the same elements in parallel paths, these elements may be referred to without the suffixes a or b, etc., since the suffixes indicate that the relative pairing or grouping of elements is indistinguishable. The present disclosure will now be described primarily in terms of addressing the above-mentioned problems associated with the use of intervening dual-band capable antenna elements, and it should be clearly understood that the present disclosure can be applied to other applications requiring or desiring multi-band operation of antenna arrays. Apply. In this regard, the following description of a multi-band multi-column cross-polarized antenna array is presented for purposes of illustration and description. Furthermore, the description is not intended to limit the disclosure to the form disclosed...

Abstract

A dual-band, dual-polarized antenna module for a mobile communication base station, which includes: a reflector plate; a radiation antenna module for transmitting and receiving two linear orthogonal polarizations in first and second frequency band, the radiation antenna module generally having a first set of radiation antenna elements operable in a first frequency band including a plurality of dipoles arranged to form generally rectangular shape, each of the dipoles substantially having a planar shape element with a convex cavity; and a second set of radiation elements operable in a second frequency band which are proximately arranged over a convex cavities in the first set of radiation antenna elements, and includes a plurality of aperture coupled patch elements generally arranged to form a quad-shape.

Description

technical field [0001] The present disclosure relates generally to communication systems and components, and in particular to multi-column antenna array architectures comprising a plurality of spatially disposed passive radiating elements with higher frequency radiating elements positioned within range of lower frequency radiating elements Orthogonal while providing independent operations between them. Background technique [0002] A base station antenna for mobile communication is designed through a space diversity scheme or a polarization diversity scheme, thereby reducing fading phenomena. The space diversity scheme refers to installing a transmitting antenna and a receiving antenna while spaced apart from each other by a predetermined distance, and has a large limitation in terms of space, and has a cost disadvantage. Therefore, a mobile communication system generally uses a dual-band dual-polarization antenna to which a polarization diversity scheme is applied. [000...
