After decades of development,a lot of research scholars proposed method to expand the bandwidth of the microstrip patch antenna,which adopts the L-shaped probe feed get a lot of attention.Because vertical section and horizontal section of L-shaped probe create inductive reactance and capacitive reactance,and both of them interact to produce resonance, this makes the antenna has wide bandwidth or multiple frequency bands. This makes L-shaped probe feed...
