Compact Wide-Angle Scanning Multibeam Antenna Array for V2X Communications

Résumé

This paper presents a wide-angle scanning multibeam Planar Inverted-E Antenna (PIEA) array for V2X communication. The compact 4-element PIEA array is designed with 0.3o spacing, which achieves 900 wide-angle scanning when a 135 phase shift is applied obtained using a 4x4 Butler Matrix (BM). The closeness of the array elements causes high mutual coupling and high cross-polarization at wider scan angles. Therefore, three novel techniques are employed to overcome the high cross-polarization and mutual coupling between antenna elements in this array. To feed the antenna array, a low-cost miniaturised beamforming 4x4 Butler Matrix (BM) circuit is designed without the use of phase shifters and conventional crossovers. The total dimensions of the compact PIEA array are just 0.4560 x1.120 x 0.0360 while the overall dimensions of the multi-beam array including Butler Matrix are 2.7310 x 2.20 x 0.046 0. This multi-beam array achieves for the first time the wide-angle scanning angles of 87 with a 3-dB beam scanning range of 120 along with the scanning angles of 20. This array design can be scaled to use as an antenna array for mm-wave applications.
