Logo Spiral Microstrip Antenna with Rotating Polarity to the Pulsar Clock

The article deals with problems related to the design of microstrip antennas. The main assumption for the designed antenna was to design a spiral logo antenna in a microstrip technique capable of receiving electromagnetic waves with a rotating polarization. The article presents the characteristics of a logo spiral antenna in a microstrip technique. The final calculation effect is presented in the form of a model implemented in the CST STUDIO SUITE and Antenna Magus program. The article presents the results of the simulations carried out for the designed microstrip antenna with rotating polarization to the pulsar clock. It is an antenna powered by coaxial cable (coaxial line), operating in the frequency range from 200MHz to 600 MHz. The directional gain of the designed antenna is from 3 dBi to 4.8 dBi. We have therefore achieved a relative work band of 133%. Polarization characteristics of the antenna indicate that the assumption related to the polarization of the antenna has been met.
