The invention relates to a multifunctional composite antenna, belongs to the field of antennae, and solves the problems that in the prior art, the number of airborne antennae is large, and mutual interference among the antennae is serious. The antenna comprises a directional antenna and an omnidirectional antenna which are formed by compounding. The directional antenna comprises a radiation unit, a guide unit and a reflection unit. The radiation unit and the reflection unit are connected with the TNC connector, and the reflection unit is fed through the TNC connector, so that the reflection unit forms an omnidirectional antenna; wherein the height of the reflecting unit is lambda / 2 + / -delta lambda 1, the height of the radiating unit is lambda / 4 + / -delta lambda 2, the height of the guiding unit is smaller than lambda / 4 + / -delta lambda 2, lambda is the antenna wavelength, and delta lambda 1 and delta lambda 2 are the height adjusting quantity of the reflecting unit and the height adjusting quantity of the radiating unit respectively. Two antennas with different functions are compounded, so that the number of the antennas is reduced, and the problem of mutual interference between the antennas is effectively improved.
Description
technical field [0001] The invention relates to the field of antennas, in particular to a multifunctional composite antenna. Background technique [0002] With the rapid development of information and electronic technology, on various airborne platforms, the system functions are constantly integrated and diversified, requiring more and more antennas to be installed on the platforms. The working frequency ranges from short wave to millimeter wave, and the antenna forms are different, especially the mutual interference between antennas of the same frequency band and the same polarization is very serious. The electromagnetic environment becomes worse, and the problem of electromagnetic interference between antennas becomes more and more prominent. In such a complex electromagnetic environment, how to solve the problem of antenna layout on the airborne platform has important research value. [0003] As known in the industry, antennas with different functions need to be install...
