MULTIBAND PLANAR MONOPOLE ANTENNA WITH SELF-SIMILAR SECTORAL SLOTS |
摘要 |
A multiband planar monopole antenna with self-similar sectoral slots is provided to obtain an impedance matching characteristic that all input VSWR(Voltage Standing Wave Ratio)s in several frequency bands are less than 2 by forming the plural slots and controlling a radian angle of a radiation surface unit. A multiband planar monopole antenna with self-similar sectoral slots includes a dielectric substrate(110), a radiation surface unit(120), a signal input and output unit(130), and a ground surface unit(140). The dielectric surface forms a main body of the antenna. The radiation surface unit is formed on one surface of the dielectric substrate in a sectoral shape entirely, receives and transmits a wireless signal and has the plurality of sectoral slots(121-123) with different sizes in a sectoral region. The signal input and output unit is integrated with the radiation surface unit by being connected to a vertex region(120a) of a lower end of the sectoral radiation surface unit and allows the radiation surface unit to transmit the signal or receive the signal. The ground surface unit for ground to set a reference electrical potential is formed over a predetermined region of the other surface of the dielectric substrate. |
