Abstract
A high band element and an antenna including a plurality of high band elements are provided. The high band element can include directors disposed above four dipoles, and the antenna can include a plurality of low band elements configured to accommodate the plurality of high band elements. The low band elements can be configured in a 1-2-2-2-1 arrangement or a 2-2-2-2-1 arrangement.
Claims19
A high band element comprising:
- four radiating elements in a single footprint;
- and
- at least one director in the single footprint,
- wherein the at least one director is disposed proximate to the four radiating elements, and
- wherein each of the four radiating elements generates a beam such that the high band element generates a beam with an approximate 45 degree pattern.
2 more elements
An antenna comprising:
- a plurality of low band elements;
- and
- a plurality of high band elements,
- wherein at least some of the high band elements include four radiating elements in a single footprint and at least one director in the single footprint, the at least one director disposed proximate to the four radiating elements,
- wherein the low band elements are configured to accommodate the plurality of high band elements in a central area between the low band elements, and
- wherein the antenna generates a 45 degree azimuth pattern.
3 more elements
A dual band antenna comprising:
- a plurality of low band elements operating at a frequency of approximately 824-896 MHz;
- and
- a plurality of high band elements operating at a frequency of approximately 1850-1990 MHZ,
- wherein the dual band antenna generates an approximate 45 degree azimuth beam pattern, and
- wherein at least some of high band elements include four radiating elements in a single footprint and at least one director in the single footprint, the at least one director disposed proximate to the four radiating elements.
