| Abstract: | The dual-frequency antenna with the same beam- width is well suited to the mobile communication base station antenna. One candidate is a corner reflector antenna whose elements are connected to a parallel feed line. However, no design equations or analysis have been published. This paper corrects this deficiency through analysis of the characteristics after integration of the two factors, spatial coupling and transmission line, for this antenna. A two dual-frequency corner reflector antenna is designed. One uses co-phase feedlines and is a wide band sector-beam antenna with a 3 dB beamwidth difference of 300 in the field pattern of horizontal plane and a return loss of less than -15 dB over a wide frequency range (from 900 MHz to 1.5 GHz). The other uses antiphase feed lines and its beamwidths can be varied by changing the corner angle while the beamwidths are coincident at two frequencies. [ABSTRACT FROM AUTHOR] |
