<p>There is proposed a wideband printed antenna including a substrate (1), a first pattern layer (2) and a second pattern layer (3). The first pattern layer (2) and second pattern layer (3) are disposed on opposite parallel first surface (11) and second surface (12) of the substrate (1). A first radiating portion (21), a first feed-in portion (22), a first grounding portion (25) on the first surface (11) of the first pattern layer (2) and the first radiating portion (21) form a first antenna by coupling energy to a second radiating portion (34) of the second pattern layer (3) of the second surface (12). A third radiating portion (31), a second feed-in portion (32), and a second grounding portion (35) of the second pattern layer (3) on the second surface (12) and the third radiating portion (31) form a second antenna by coupling energy to a fourth radiating portion (24) of the first pattern layer (2) on the first surface (11). After the first feed-in portion (22) sends out a signal, the first connecting portion (23) synergizes energies radiated by the first antenna and the second antenna to form a third antenna. Similarly, after the second feed-in portion (32) sends out a signal, the second connecting portion (33) synergizes energies radiated by the first antenna and the second antenna to form a fourth antenna.</p> |
