“…It provides a high data transfer rate which is required for time critical response. DSRC application includes Electronic Toll, Electronic parking, warning of an approaching emergency vehicle and highway rail intersection warning [1]. Therefore it is worth full to design an antenna which operates in both of these bands.…”

In this paper, a CPW-fed dual band antenna for Circular Polarization (CP) is proposed and fabricated. CP is achieved using an 'L' shaped radiating patch and a one corner truncated slot in the ground plane. Dual band CP is achieved by connecting one end of the 'L' shaped patch to the ground plane and adding a stub to the ground plane. The proposed antenna has impedance bandwidths (S 11 <-10 dB) of 34% (2.2-3.1 GHz) and 42% (4.6-7.1 GHz), and Axial Ratio Bandwidth (ARBW) of 34% (2.2-3.1 GHz) and 26% (5-6.5 GHz). The antenna is Right Handed Circularly Polarized (RHCP) in both the bands. A parametric study is also presented for the better understanding. The measured results show a good agreement with the simulated results.

“…The radio frequency (RF) signals are transmitted from satellites in geostationary or highly elliptical orbits and are modulated with quadrature phase shift keying (QPSK). Usually, a single antenna mounted on the rooftop of a vehicle is used for mobile SDARS reception [3]. In severe multipath fading scenarios, e.g.…”

For a fast scan-phase satellite radio antenna diversity system a noise correction method is presented for a significant improvement of audio availability at low signal-to-noise ratio (SNR) conditions. An error analysis of the level and phase detection within the diversity system in the presence of noise leads to a correction method based on a priori knowledge of the system's noise floor. This method is described and applied in a hardware example of a satellite digital audio radio services antenna diversity circuit for fast fading conditions. Test drives, which have been performed in real fading scenarios, are described and results are analyzed statistically. Simulations of the scan-phase antenna diversity system show higher signal amplitudes and availabilities. Measurement results of dislocated antennas as well as of a diversity antenna set on a single mounting position are presented. A comparison of a diversity system with noise correction, the same system without noise correction, and a single antenna system with each other is performed. Using this new method in fast multipath fading driving scenarios underneath dense foliage with a low SNR of the antenna signals, a reduction in audio mute time by one order of magnitude compared with single antenna systems is achieved with the diversity system.

“…Modern vehicles are equipped with a lot of antennas to facilitate a reliable wireless communication that enables a running vehicle to connect with the outside world and tracking geological position system for various applications in addition to basic AM/FM and TV antenna [1]. Existing roof-mounted mast antenna as whip antenna, which has been used for decades to receive radio signals, causes many disadvantages such as easy breakable, wind noise, and limitation of industrial design.…”

In this paper, a vehicular antenna design scheme considering the vehicular body effects is proposed. A wire antenna for GPS and LTE is implemented on the plastic plate, then it is mounted on the front glass. The outputs are commonly used to share the feed. It is necessary for GPS to increase the right hand circularly polarization (RHCP) gain near the zenith and to reduce the axis ratio while for LTE to increase the horizontal and vertical polarization (HP and VP) gain in the horizontal plane. Also for LTE, multiband characteristics are required. In order to achieve the specified performance, the antenna shape is optimized by Parato genetic algorithm (PGA). When the antenna is mounted on the body, the performance is seriously changed. To evaluate performance of the antenna mounted on the body with a complex shape, a commercial electromagnetic simulator (Ansoft HFSS) is used. To apply electromagnetic results output by HFSS to PGA algorithm operating on the MATLAB, MATLAB to HFSS linking program via Visual BASIC (VB) script was used. It is difficult to carry out the electromagnetic analysis with the whole body because of limitations of the calculating load and memory size. To overcome the limitation, we consider only a predominant part where it has an influence on the performance. It is presented that degradations caused by the body are improved through a series of optimization stages. The simulation results obtained clearly show that it is well optimized at 1.575 for GPS and 766.5 MHz and 2.135 GHz for LTE, respectively.
