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.

“…Generally, the ground plane of mobile devices is rectangular. Studies have shown [3] that optimum coupling can be achieved by placing the feeding structure along the longer side of the ground plane. However, for the second-order mode, the magnetic field is the minimum at the center of the ground plane, where the slot-type structure would couple weakly with this mode.…”

A dual-band tunable-slot-type ground radiation antenna is proposed. The feeding structure consists of a coplanar waveguide and a lumped capacitor to excite currents for first-and second-order resonant modes of the ground. The resonant frequencies of both bands are controlled using a series combination of a capacitor and an inductor. The proposed design may be an attractive choice for mobile devices owing to its compact geometry and tunable operating frequencies. The measurement and simulation results of the proposed antenna show good agreement, indicating good impedance matching and radiation performance.

“…In our test, the receivable signal of the cross-polarization is so weak that the influence of the noise injection is obvious. Unlike most reported microstrip multiple function antennas which realize the same radiation pattern at different frequencies [2][3][4][5], different patterns at the same frequency [6], or dual-band dual-mode with two ports [7], the proposed antenna can achieve two different types of radiation patterns at three individual frequency bands. Comparing with the CRLH antennas in [8][9], our design has its own advantages and disadvantages.…”

A substrate integrated waveguide (SIW) cavity-backed annular ring slot antenna with multi-band multi-mode characteristics is proposed in this communication. The antenna consists of an SIW cavity and an annular slot on top surface as the radiator. Two patch-like radiation patterns and one monopolar radiation pattern at three different frequencies are excited by the single fed antenna. Moreover, each operating frequency can be individually adjusted. A prototype is fabricated and measured to validate the theoretical analysis. Good agreement between the simulated and measured results of the input reflection coefficients and radiation patterns is achieved. Compared with other designs, the proposed antenna has features of simple structure, multi-band multi-mode and frequency-tunable characteristics.Index Terms-Antenna, cavity-backed, multi-mode, multi-band, substrate integrated waveguide (SIW). 0018-926X (c)
