Problems solved by technology

[0006] The traditional sinusoidal antenna is a planar structure with a two-way radiation pattern. In order to achieve one-way radiation, it is usually necessary to place a metal back cavity filled with absorbing materials behind the radiator [3] , but this method will lose part of the radiated energy and reduce the antenna gain

Description

technical field [0001] The invention relates to a broadband fully polarized directional antenna, in particular to a conical four-arm sinusoidal antenna. Background technique [0002] As an important part of transmitting and receiving electromagnetic waves, antennas are an important part of radio equipment and systems. Many modern wireless systems such as communication and radar systems require antennas to work effectively in a wide frequency range. The main electrical parameters of the antenna, such as impedance, gain, pattern, axial ratio, etc., have their respective bandwidth limitations. The bandwidth of the antenna should be defined by the narrowest bandwidth, that is, the main performance indicators of the antenna within this bandwidth can reach Specifies the requirements. [0003] The scaling principle of the antenna states that if the model size of the antenna changes in the same proportion as the operating frequency (or wavelength), the performance of the antenna re...
