Design of Circularly Polarized Antenna for Vehicular GNSS Application
For vehicle roof tops, a circular polarized square-shaped slot type antenna is proposed. The higher GNSS band which ranges from 1.559 to 1.606 GHz, is covered by the proposed antenna. The patch, square slot and chemfering edges of patch work together to produce circular polarization modes that significantly increase the antenna 3-dB axial ratio (AR). The AR for the antenna element in the simulations is 1.19 dB, the axial ratio bandwidth is 65 MHz, the VSWR is near about 1, the S11 parameter is less than −10 dB, and the gain is 8 dBic over the frequency range. It is made of poly vinyl chloride with dimensions of 54 mm x54 mm x 6.8 mm. The design procedure is explained in depth, as well as the antenna operating mechanism. A completely functional prototype was created and measured to confirm the proposed antenna's performance. When the measured voltage standing wave ratio (VSWR) and the S11 Parameter are compared with the observed data, a satisfactory agreement is found. Future multiband antenna designs for automotive communication could incorporate this antenna along with 4G/5G/6G band antenna.
