A monopolar patch antenna with a V-shaped slot for Car-to-Car (C2C) and WLAN communications is presented in this paper. To widen the impedance bandwidth of the antenna, techniques of adding shorting pin and a V-shaped slot are applied to an equilateral triangular patch. By properly placing the shorting pins on an equilateral triangular patch, two operating modes, TM 10 and TM 20 , are obtained. The presence of the V-shaped slot can generate an additional TM 11 mode. These three resonances found in the operating frequency bandwidth resulted in a wideband characteristic. The proposed antenna can operate from 4.82 to 6.67 GHz for the reflection coefficient  -10 dB with the gain of around 5.0 dBi. In addition, an omnidirectional radiation pattern is yielded by a coaxial centred-fed probe excitation. The antenna has a thickness of 0.09 g (at the centre frequency of 5.5 GHz), which is easily hidden on the roof of a vehicle for C2C communication. This proposed design can also be used as indoor base station antennas for WLAN communication.

“…respectively, were tested. In, [9] and [10], ray tracing based simulations have been applied for analyzing impact of three and six antenna positions, respectively. To the authors' best knowledge, though, no (measurement-based) investigations to study the impact of antenna placement at different positions on the car, other than on the roof and windscreen, have been presented in the literature.…”

In vehicle-to-vehicle (V2V) communication systems the antennas are prone to shadowing and the antenna gain is dissimilar even for same antenna elements if mounted at different positions on the car. This paper investigates the impact of antenna placement based on channel measurements performed with four omni-directional antennas mounted on the roof, bumper, windscreen and left-side mirror of the transmitter and receiver cars. Results suggest to use antennas with complementary characteristics, e.g., antennas on each side, mounted on the roof and bumper, to exploit diversity and decrease the effect of shadowing.

“…In [1], [2], [3] only investigations on antenna placement for broadcast services in the resonant region, where the dimensions of the car are in the order of the wavelength, or for communication applications below 1 GHz, where a typical car has the dimension of 15 to 20 wavelength, were publisched. The publications [4], [5], [6] deal with the placement of Car2Car antennas concentrating only on the general placement like roof, mirrors or underneath the car and its influence on the communication channel. In [7] Car2Car antennas are reviewed within a roof antenna module and mounting conditions like limited ground plane and roof curvature are taken into account.…”

The Car2Car communication will use a reserved frequency band at 5.9 GHz. One of the key requirements for a Car2Car antenna is that the gain is concentrated in the horizontal plane, which is a problem due to the limited ground plane of a car roof. The influence of roof curvature, roof racks and panorama glass roofs were investigated to quantify them. To the authors knowledge such measurements have not been published yet. Three different antennas were simulated and measured on round ground planes and real car roofs in different configurations. The configuration with a panorama glass roof showed an unexpected high loss of gain in the direction of the glass roof in the range of 15 to 20 dB which result in a drastically reduced communication range to the front direction. This phenomenon is still under investigation.
