A new planar magneto‐dielectric substrate (MDS) is used for miniaturising a rectangular microstrip patch antenna for radio frequency identification (RFID) applications. The proposed magneto‐dielectric unit cells are embedded underneath the microstrip patch. Increasing the constitutive parameters of the host substrate decreases the size of the antenna. This use of a MDS as the host substrate allows the antenna size to be reduced by up to 80% compared with a conventional microstrip patch antenna, and the proposed smaller antenna exhibits almost the same performance. The simulated and measured results show a good agreement. The magneto‐dielectric layer is thin enough to be embedded underneath the antenna. The proposed antenna offers a reasonable impedance bandwidth from 847 to 853 MHz. The antenna is therefore suitable for RFID applications.
