Abstract:
1. A switched beam smart antenna apparatus, comprising: a first, a second, a third, a fourth, a fifth, a sixth, a seventh, and an eighth beam adjusting elements; a first, a second, a third, and a fourth radiation strips positioned within an area surrounded by the first to the eighth beam adjusting elements; a radiation strip control module for selecting either the first and the second radiation strips or the third and the fourth radiation strips to transmit signals; a first beam control module coupled with the first and the second beam adjusting elements; a second beam control module coupled with the third and the fourth beam adjusting elements; a third beam control module coupled with the fifth and the sixth beam adjusting elements; and a fourth beam control module coupled with the seventh and the eighth beam adjusting elements; wherein when the first beam control module conducts the first and second beam adjusting elements, the third beam control module does not conduct the fifth and sixth beam adjusting elements, and when the second beam control module conducts the third and fourth beam adjusting elements, the fourth beam control module does not conduct the seventh and eighth beam adjusting elements; wherein the first beam adjusting element has an equivalent current path of a length less than or equal to a total length of an equivalent current path of the first radiation strip and an equivalent current path of the second radiation strip, but a total length of an equivalent current path of the first beam adjusting element and an equivalent current path of the second beam adjusting element is greater than the total length of the equivalent current path of the first radiation strip and the equivalent current path of the second radiation strip.
