Short monopole antenna
SpletThe antenna AD-27/DB-3512-S is a dual-band monopole/dipole mobile antenna intended for use in heavy-duty mobile applications. The antenna is covering a frequency range from 30 to 108 MHz and from 225 to 512 MHz. Due to the special monopole design in the radiator, the ground for the VHF is not needed. That way the antenna can be also installed ... SpletDUAL-BAND MONOPOLE ANTENNA Lengths of the open-circuited sides of the tuning stubs are 4.8 mm. Insertion losses of the passband for the simulated and FOR WiMAX WIRELESS DEVICES measured results are 0.16 and 0.36 dB, respectively, and return X. L. Sun, S. W. Cheung, and T. I. Yuk losses for both simulated and measured results are greater than ...
