The radiation characteristics of the first higher order mode of microstrip lines are investigated. As a result, a simple travelling wave antenna element is scribed, having a larger bandwidth compared with resonator antennas. A method to excite the first higher order mode is shown. A single antenna element is treated theoretically and experimentally, and an array of four antenna elements is demonstrated.

    • ...The study of planar leaky-wave antennas (PLWAs) have received much attention since the first proposal by Menzel [1], due to their inherent properties of low-profile, low-cost, frequency beam scanning, high directivity, simple feeding, and easy integration with others planar circuits and microwaves components [1]‐[10]...

    • ...By the contrary, when the upper plate of the strip is truncated, upward radiation is accomplished in the same way like the one described for the leaky-mode in conventional microstrip LWAs (MLWAs) [1]‐ [4] and half-mode MLWAs (HMLWAs) [8], [18], [19]...

    • ...After this pioneering work, leaky-wave antennas have been the subject of many investigations [2, 3]. The planar printed-circuit leaky-wave antenna arrays with discrete periodic energy leakage have, however, been the focus of research in recent years [4, 5]. The interest in these new antenna types stems from their ability to produce both broadside pencil beams and scanned conical beams and their structural simplicity such as lowprofile ...
