Flexible Efficient Quasi-Yagi Printed Uniplanar Antenna


Flexible Efficient Quasi-Yagi Printed Uniplanar Antenna


A flexible quasi-Yagi printed antenna that is a compact, economical directive radiator is demonstrated. The easy uniplanar design incorporates an arc-formed strip, which serves as a near-field resonant parasitic (NFRP) element, and a coplanar-waveguide (CPW)-fed semiloop antenna. The simulated and experimental results that are in sensible agreement make sure the forward endfire nature of the antenna. The entire electrical size is solely $zero.17 lambda_0 times 0.forty threelambda _0$, while having a high radiation potency to achieve a five.76¬†dBi realized gain. A backward endfire version illustrates the radiation principles of the planning. By mounting the uniplanar antenna conformally on a cylindrical structure, it’s demonstrated numerically and experimentally that its radiation performance characteristics are maintained, confirming that only minor effects are introduced beneath bending conditions.
