We will introduce a case that achieved low VSWR over a wide bandwidth in the high frequency band.
We would like to introduce a case where we developed a "multi-band antenna." In the frequency range of 300 MHz to 6 GHz, we aimed to divide it into 5 bands as needed, achieving vertical polarization with omnidirectionality in the horizontal plane and a VSWR of less than 3.5 for each band. As a solution, we used a shortened dipole antenna element for the low-frequency band and a biconical antenna element for the high-frequency band, creating a central-fed hybrid configuration that allows for a single shared input terminal. [Development Overview (Partial)] ■ Challenges - Shared with a single input terminal - Wideband element ■ Results - The antenna, with a cover, achieved a diameter of φ60mm × 300mm and a weight of less than 1 kg. *For more details, please refer to the related links or feel free to contact us.
