<p>The system has radiating elements (100-102) formed with dimensions and shapes to cover a sub-band of frequencies of a predetermined frequency band. The radiating elements are connected to power sources (120-121), respectively. Each of the radiating elements is coupled with the adjacent radiating elements by intense electromagnetic couplings (130, 131) to obtain current distribution on the radiating elements. Distance between radiating elements is in a range of lambda/30 and lambda/300. The radiating elements are rolled up in same direction.</p> |
