I want to match RainSun chip antenna GPS5503 impedance.
Antenna is place in test board of 1.6mm thick Fr4 Substrate.Test board dimensions are as per datasheet expect substrate which is of 0.8mm thick Fr4 Substrate.
Attached here is the test board photgraph.
First I've placed 0 Ohm resistor in series and the impedance is 6-j32 and then i've tried to match this with 50 ohms as per ansoft designer SV with shunt capacitance 5.5pF and series inductance 4.87 nH but what i get was 6.5+j23.
Kindly suggest me how to proceed further in this regard.
