In this paper, two monopole antenna structures called by the authors as “Hello 1” and “Hello 2” have been designed based on screen printing technology on the flexible paper substrate of 210-um thickness to cover very wide frequency range focusing on two WLAN bands. The designed antennas have the dimensions of 42 × 28 mm2 with the return loss of over 20 dB for “Hello 1”, and over 25 dB for “Hello 2”...
Recently, paper has been mentioned in many research studies [1-4] as a good choice of a substrate material for flexible electronics. In this paper, the E4D paper has been characterized by the cavity perturbation method, then a monopole antenna structure, called “Sapin” by its shape, has been designed on it to cover a very wide frequency range including two WLAN bands. The proposed antenna is rather...
