The noumenon of antenna is to use the type of 1/4 wavelength and coaxial collinear, which is with impedance conversion of the transmission path of the antenna and 16% bandwidth utilization. We use FR4 which is the low cost material, and print the designed Coaxial Collinear Antenna to the substrate sheet of FR4. Then we migrate the electronic phase to increase the antenna gain by the design of wavelength, and correct the antenna radiation pattern. In order to shift the impedance, we also add the characteristic impedance converter to the path of electric current. The standard is that return loss is lower than -6dB. The operable frequency range of the antenna is from 2.3GHz to 2.7GHz, which the maximum gain can reach 5.6 dBi, and the dimension of noumenon is only 360 x 15 (L x W).
