In this paper a wideband cost-effective screenprinted millimeter-wave log periodic antenna is presented. The proposed antenna configuration is implemanted using a screen printed process on a 100 µm Zeonex thin film (εr = 2.2 and tan (δ) = 0.009).The metalization layers are made off nano particles silver ink (σ = 3.3 • 10 6 S/m). Measured performances and simulations are in good agreements (peak measured gain of 6.5 dB and simulated peak gain of 7.5 dB). Overall size of the printed prototype is 15x20 mm 2 . The obtained results demonstrate the feasibility of cost-effective high-performances screen printed millimeter wave antenna.
