Domestic and foreign scholars have been exploring the 433 MHz printed antenna with high gain and miniaturization for many years. However, there are two main trends in the design of 433 MHz printed antenna by previous scholars: one is to sacrifice size to ensure high gain, such as the structural scheme in literature [3]; The other is to sacrifice gain to ensure size miniaturization, such as the scheme in reference [4].
Taking into account the effective size and gain characteristics of the antenna is the difficulty in the design of 433 MHz miniaturized printed antenna. Based on the research experience of domestic and foreign scholars on 433 MHz printed antenna, a 433 MHz miniaturized spiral printed antenna is designed based on the 1/4 wavelength monopole antenna. The simulation results show that the antenna occupies only 20×35 mm2 and the effective gain is -4.14 dB.
