Abstract :
We proposed a dual-band S-shaped fractal antenna with a compact orthogonal dipole for miniaturization and a reflection mirror for gain improvement. Considering the applications of vehicular navigation systems, the proposed antenna is designed to cover dual-band frequencies of L-Band (1.616 GHz ± 5 MHz) and S-Band (2.492 GHz ± 5 MHz). The -10 dB impedance bandwidths are 238 MHz and 340 MHz respectively for the lower band and the higher band, with an excellent isolation in the whole operating frequency range. The results of simulation and measurement agree with each other quite well.
