Analysis of CPW-Fed Modified Z-Shaped Reconfigurable Antenna for Automotive Communications

摘要

In this article, a coplanar waveguide-fed planar antenna is proposed for vehicular communication applications. The proposed antenna consists of a modified Z-shaped radiator and designed on a FR4 substrate with a footprint of 40 × 30 × 1.6 mm~3. The design is further made reconfigurable structure for providing switching among the operating bands of the antenna by incorporating the BAR64-03 W PIN diodes. The proposed antenna operates the switching among the complimentary operating bands exist under 2.39-2.8 GHz, 3.32-4.11 GHz, 7.34-9.03 GHz has been observed under different switching conditions. The proposed design also exhibits circularly polarized radiation characteristics under operating bands makes this antenna as a hybrid reconfigurable design. The measured results of fabricated antenna are in good correlation with simulated results. The radiation performance is analysed for stand-alone reconfigurable antenna and the virtual environment on a vehicle body.
