Dual-band Planar Micro-Strip Antenna |
摘要 |
To meet the requirements including dual-band, a high gain, and a broadside radiation formation, a dual band planar micro-strip antenna utilizing antenna array is provided. One array element includes a rectangle-shaped micro-strip antenna and an arrow-shaped micro-strip antenna. A first resonant frequency is determined by a length of the rectangle-shaped micro-strip antenna. Slots are dug for satisfying a second resonance frequency. Curved surfaces of the arrow-shaped micro-strip antenna designed according to an ellipse equation so that a frequency resonance is reached under both the first resonant frequency and a second resonant frequency, and a broadside radiation formation is thus generated. A T-shaped jointer distributes power between antenna elements according to the output impedances of the antenna elements. An L-shaped band-stop filter located on the T-shaped jointer is utilized to suppress frequency resonance resulted from multiples of the first resonant frequency.
