Ahalf wavelength patch antenna has an input impedance 200 ω when it is fed directly at (a) calculate a suitable fed point to achieve 50 ω input impedance if fed with a 50 the edge. the patch is 5 cm long and 6 cm wide. transmission line (e. g., a microsrip-line). (1 p) a 10 cm wire is cut apart in the middle and fed with a differential current that has an amplitude of 100 ma at a frequency of 1 ghz. (b) what is the electrical (e) field strength at 3 m, when the angle to the dipole antenna is 20° tilted from the boresight (orthogonal to the wire), i. e. tilted in the plane of the wire, 20 degrees towards any of the arm ends. (1 p) (c) what e-field strength would a circular polarized antenna sense at this position? the circular polarized antenna has 0 dbi gain and 0 db axial ratio in the direction of the wire.
