Résumé

Centered on two inverted-V dipoles fabricated in a crossed configuration and a typical planar reflector, this article introduced a lightweight and high gain antenna with reconfigurable polarisation. The proposed antenna could produce four separate polarizations, including vertical.polarisation (VP), horizontal polarisation (HP), right-hand circular polarisation (RHCP), and left-hand circular polarisation (LHCP). polarisation in a circle (LHCP). The polarisation diversity was guided by a pair of inverted-V dipoles, where each The dipole included an integral matching circuit as well as a microstripbalun. Making use of a crossed inverted-V We were able to achieve compactness in scale by using a ground plane as the common reflector. A dipole antenna with strong directivity and a larger beamwidth than a standard dipole antenna. To assess the success of We built a sub-6GHz antenna with a Taconic TLX-9 substrate, which had been modified. The planned antenna had a calculated 10-dB impedance bandwidth and a relative permittivity of 2.5.(752 MHz) (5.376 GHz to 6.128 GHz). The peak gains for the VP, HP, RHCP, and LHCP operations were reported at 5.8 GHz is approximately 5.2 dBi, 4.61 dBi, 5.25 dBic, and 5.51 dBic. Furthermore, the half-power On both polarizations, the beamwidth (HPBW) was greater than 78. inside the operational band.
