Abstract
A low-cost W-band leaky-wave antenna with two-dimensional scanning capability is presented. By using the low-loss transversal long-slot array structure with a single-layer parabolic reflector, the antenna realizes a passband from 85 to 102.8 GHz with Voltage Standing Wave Ratio <2. This antenna has a backward radiation direction, which changes with frequency in one dimension, and with the feeding wave front direction in the other dimension. The maximum sidelobe is measured to be −14.2 dB, 5 dB lower compared to the previous-published longitudinal long-slot array. A low-cost, low-loss, low-profile design is provided for W-band 2-D beam scanning, with backward scanning capability, which is easy to fabricate and could be used for high-solution sensing and point-to-point communications.
