在本文中，提出了底物的平面插槽天线（PSA），这是由底物综合波导（SIW）腔的支持，以解决最大增益方向偏置的问题，根据插槽天线的辐射原理，通过介绍了ulias的范围，并通过介绍了最大的范围。通过。在结构优化和测量之后给出了5.8 GHz的最大增益为5.28 DBI，总厚度小于λ/4。
In this paper, a directivity‐enhanced planar slot antenna (PSA) backed by substrate integrated waveguide (SIW) cavity is proposed to solve the problem of maximum gain direction bias. According to the radiation principle of slot antenna, the reason for maximum gain direction bias is explained and the solution has been given. Ulteriorly, the problem of frequency bias caused by changing the directivity is also explained by resonance modes and solved by introducing the metal via. An example with 5.8 GHz which has the maximum gain of 5.28 dBi and the total thickness less than λ/4 is given. After structural optimization and measurement, the maximum radiation direction of improved antenna is 0° from the normal direction of antenna surface, and it maintains the good radiation performance and small size of the traditional PSA backed by SIW cavity.
