This article presents the design of a multipattern antenna with pattern switching for vehicular communications. The proposed antenna has four triangular patches integrated onto a split square ring (SR) resonator to operate at two distinct frequencies, viz. 2.4 and 3.5 GHz. The proposed antenna is designed with a view to enhancing the link reliability of Wireless Local Area Network (WLAN), WiMax, and vehicle to vehicle communication frequencies. Each triangular patch is separately excited using a microstrip line feed to enable beam steering. The ground plane of the antenna is embedded with two SR slots to improve the bandwidth and radiation performance. Further gain enhancement is achieved by loading the antenna with a plane reflector located at a distance of 20 mm from the antenna's ground surface. In reality, this reflector is realized using the vehicle's roof which provides gain enhancement up to 5.2 dBi at 2.4 GHz and 4 dBi at 3.5 GHz. By exciting single to multiple ports sequentially 16 different radiation patterns are obtained, which provides high‐gain omnidirectional coverage. The prototype antenna is fabricated and the simulation results are verified using experimental measurements. From the results, it is evident that the proposed antenna is suitable for vehicular communication applications.

“…Furthermore, this antenna provides only six different radiation patterns. In Reference a dual‐band antenna with beam‐steering capability is reported. The antenna employs two capacitively coupled square loops and the work focuses only on directivity enhancement and offers only a low impedance bandwidth in both the operating bands.…”

“…These antennas are capable of directing the beam only toward the intended direction avoiding the interference/noise sources [3] [4]. Consequently, these antennas provide better signal to interference ratio (SIR) enabling the communication system to support high-rate data-transmission.…”

“…To steer its beam, the current distribution over the spiral arm is varied using switches, but the antenna has limited beam steering capability and suffers from pattern variations. Four space quadrant consistent patterns switching were achieved using star [9] and printed square loop antennas [10]- [13]. These employed four feeds which are switched one at a time.…”
