Abstract： |
Antenna structure including radiating element, metal ground and feed line is printed on PCB. From two planes of PCB, the metal ground is one metal plane of not containing radiating element of antenna, but containing rectangular metal patches and T shaped metal patch for simulating parts in wireless communication system except antenna. The radiating element includes one rectangular metal patch, one triangular metal patch and two pieces of trapezoidal metal patch. Being connected to the radiating element, the feed line uses microstrip line or probe etc other forms. Microstrip line and the radiating element are printed in same face of PCB. The metal ground is printed in the other face. Based on requirement of working frequency band, whether two pieces of trapezoidal metal patch are selected is determined. Features are: wide band, small size, easy of preparation and integration, being suitable to mobile terminal in wireless communication expressly. |
