| 摘要 |
<p>The present invention relates to a directional antenna comprising a dipole-configured active element, including two arms (2a, 2b), and a reflector element, including two parts (3a, 3b) inclined towards the arms (2a, 2b). The electrical length of the active element is equal to or less than 0.4 times and equal to or greater than 0.15 times the wavelength associated with the frequency of the radio link or communication. The angle between each inclined part (3a, 3b) of the reflector element and a line (4) parallel to the arms (2a, 2b) is equal to or greater than 15º and equal to or less than 45º.</p> |
