This article proposes an adaptive vehicular antenna array with four analog variable phase shifters and a corporate feed network to tilt the main beam in any broadside direction and scan the blind spot zone. Square modified cantor fractal geometry of each element achieves 65% surface reduction, measured 75 MHz bandwidth, 5.5 dB gain, −32 dB return loss, and an array gain of 11 dB at 5.88 GHz dedicated short range communication service frequency band. © 2015 Wiley Periodicals, Inc.
