Abstract

Mechanical flexibility along with size, weight and cost are among the main challenges for future wearable electronic devices. In this paper, the effects of bending on a planar flexible Yagi-Uda antenna operating at WLAN (IEEE 802.11) 5.2 GHz are reported. The flat antenna achieves a relative bandwidth of 13% over which S₁₁ is less than -10 dB, a realized gain of 8.1 dB, a front-to-back-ratio of 17 dB and a half-power beam width (HPBW) of 89°. The results showed that the antenna maintained the WLAN (5150-5350 MHz) matching bandwidth required under a wide range of bending angles ΨB.
