Abstract:
1. A dual polarization broadband antenna having a single continuously-connected pattern, comprising: a planar radiation device having a rectangular structure and having a plurality of folded dipole elements formed in a single continuous closed-loop pattern, the rectangular structure formed by outer lines of each of the dipole elements; and a feeding portion configured to feed signals to the plurality of folded dipole elements formed on the radiation device, wherein the plurality of folded dipole elements includes a first folded dipole element to a fourth folded dipole element, and the feeding portion comprises one of four feeding points located between each of the folded dipole elements, the four feeding points being formed to cross each other and configured to simultaneously feed the signals, and wherein the second folded dipole element and the fourth folded dipole element have the same length, the first folded dipole element has a longer length, and the third folded dipole element has a shorter length such that squint error is decreased when alternate feeding points are fed.
