Embodiment
[0022] In this embodiment, the antenna works in the X-band, and the central operating frequency is 10 GHz. The dielectric substrate 1 is a Rogers 5880 dielectric board with a relative permittivity of 2.2 and a thickness of Hc=0.508 mm. The dimensions of the antenna are as image 3 As shown, the specific parameters are as follows: image 3 As shown, the specific dimensions of the antenna are: Rc=9.7mm, Lms=4.3mm, Wms=1.5mm, Lcpw1=6.65mm, Lcpw2=1.35mm, Gcpw=0.5mm, Ls1=5.1mm, Ls2=3.5mm, Ws= 0.8mm, theta=120°, Os=1.2mm, Dv=1mm, Pv=1.4mm, Ov=1.15mm.
[0023] The antenna is at the central operating frequency of 10GHz, and the hexagonal substrate is integrated into the waveguide cavity 5 TM 110 The simulation results of the mode electric field distribution are as follows: Figure 4 As shown, it can be seen from the figure that the first rectangular radiation slot 7 and the second rectangular radiation slot 8 are fed in the same phase at this time; the test results of the reflection ...
