This MSc project describes the design of a microstrip slot antenna at 10.587 GHz for Doppler frequency measurement. A lot of techniques have been discussed in the literature review for designing a microstrip slot antenna and its merits and demerits. In hypothesis testing plenty of ways were taken to design the microstrip slot antenna. At last a centre-fed microstrip slot antenna was designed where the width of the microstrip transmission line was calculated from the TXLINE calculator; the length and the width of the slot were found from the complex impedance of the radiating slot and this was...
