Design of a low-profile dual polarized log-periodic antenna
In this dissertation, a low-profile dual-polarized log-periodic antenna has been designed. This antenna consists of a printed log-periodic dipole antenna and a top-hat loading log-periodic monopole antenna. Over the operating band of 2-6 GHz, simulation results show that the VSWR of this ant...

| description | In this dissertation, a low-profile dual-polarized log-periodic antenna has been
designed. This antenna consists of a printed log-periodic dipole antenna and a top-hat
loading log-periodic monopole antenna.
Over the operating band of 2-6 GHz, simulation results show that the VSWR of this
antenna is less than 2 with a height of 8 mm (0.107 𝝺o ). A half-power beam width of
69±6° is achieved for the horizontal direction and 45±6° is achieved for the
vertical direction. At the maximum radiation direction, the cross-polarization is
smaller than –30 dB and front-to-back ratio is large than 11 dB |
