“…Liquid crystal polymer (LCP) as a favourable flexible material has gained much attention, owing to its impressive loss tangent, static dielectric constant, extremely low water absorption and low thermal expansion coefficient [1–4]. Wireless area networks (WLAN) is a wireless communication network which is used for two or more devices in a limited area, includes dual‐band frequency of 2.4–2.4835 and 5.15–5.875 GHz [5, 6]. As the 2.4 GHz band becomes more crowded, many users are opting to use 5 GHz band.…”

A compact flexible filter based on 0°feed structure with ultrathin liquid crystal polymer substrate is proposed firstly. An open-ended stub is introduced to improve the out-band rejection. The presented flexible filter with dimension of 6.48 × 9.89 × 0.086 mm 3 is operating at WLAN of 5.15-5.875 GHz, which will alleviate the channel congestion of 2.4 GHz. In the case of flat, the measured minimum insertion loss is 1.9 dB at 5.61 GHz and the return loss is better than 16.45 dB. The bending behaviour of the compact flexible filter is also analysed. Compared with the flat case, the return loss is optimised by 0.45 dB, the maximum deterioration of insertion loss is 0.13 dB in case of R = 10 mm, and the transmission zeros position are invariant. Good agreement is obtained between the flat and the bending situation, which shows that the presented flexible filter is promising for the wearable applications.
