“…One objective is to develop models that allow a quick and reliable design process, speeding up time to production and reducing expensive testing times. Many investigations have concentrated on glass based antenna systems for broadcast reception in automobiles [1]- [11]. Several papers report vehicle simulations [3], [5], [7]- [11] but there is still a considerable way to go to be confident that their predictions are sufficiently accurate.…”

Several papers report vehicle simulations [3], [5], [7]- [11] but there is still a considerable way to go to be confident that their predictions are sufficiently accurate. Other authors have examined the performance of antennas for higher frequency telematics systems [12]- [15] although modelling is much more difficult at these higher frequencies due to constraints on computer power and memory.…”

A new printed antenna system mounted in an aperture in the roof of a car is evaluated for broadcast signal reception from 88-108 MHz. Results from simulations on the vehicle are compared with measurements. The overall performance of the antenna is also compared to common types of vehicle antennas, the roof monopole and a glass based antenna. Overall the average gain of the antennas was better than 3 dBi for vertical polarization and 10 dBi for horizontal while the input return loss was generally better than 2 dB before matching sections in the tuners and comparable with common automotive antennas. The antennas in the roof aperture offer an alternative place to mount antennas on automobiles.

“…However, original equipment manufacturers (OEMs) have size and location constraints on antenna placement in order preserve vehicle aesthetics [3,4]. In [5] the researchers investigated the performance of a printed monopole frequency modulation (FM) antenna located on the side window and in a recessed roof panel with respect to an FM mast antenna installed on the roof. The effect of loading a printed meander line monopole antenna by the vehicle glass was investigated in [6].…”

“…It was shown that the lower the windshield tilt angle, the better the measured LAG and the better the GPS system performance. The results presented in [3][4][5][6][7][8][9][10][11][12][13][14] indicate that antenna pattern coverage is degraded because of the complex reflecting environments surrounding the antenna.…”

The placement of global positioning system (GPS) patch antennas on vehicles is important as its location directly affects navigation system performance. GPS antennas mounted on the front glass window has been adopted by several vehicle manufacturers around the world. In this work, we present a detailed experimental study on the effect of antenna mounting parameters as well as shorting it to the roof of the vehicle on its performance characteristics. Specifically, we investigate the effect of the glass tilt angle, the distance of the antenna from the rooftop of the vehicle in addition to grounding it to the rooftop versus not‐grounding to the rooftop of a vehicular platform.

“…There are many locations in which low frequency antennas can be placed on an automobile but in most cases the glass window areas are used. Several studies have reported modelling studies for this type of antenna [1][2][3][4][5][6][7] using methods ranging from geometric optics to the method of moments and time-domain techniques. Many of these studies used simplified body shapes lacking design detail and omitted the glass substrates supporting the antennas.…”
