[0019] Such as figure 1 , 2 As shown, a microstrip vertical loop antenna includes a rectangular dielectric substrate 1, an antenna patch layer 2 attached to the upper surface of the dielectric substrate 1, and a metal ground layer 3 attached to the lower surface of the dielectric substrate 1. The antenna patch Layer 2 includes a radiation patch 21 and a microstrip feeder 22 ; the radiation patch 21 is connected to the microstrip feeder 22 .
[0020] combine figure 1 , Part 1 in the figure is the dielectric substrate of the antenna, its thickness is 1mm, and its relative permittivity is 2.52; Part 2 in the figure is the patch layer of the antenna; Part 3 in the figure is the metal ground layer.
[0021] combine figure 2 , the length L1 of the microstrip feeder 22 is 3 mm, the width W1 is 0.6 mm, the metal ground layer is equal in width to the dielectric substrate, and the length is equal to the length of the microstrip feeder 22; the radiation patch 21 is an arrow-feather-s...
