Low-frequency antennas below 1 GHz are dragging the attention of researchers due to its applications such as defense, mining, and underground communications. Designing a miniaturized structure with acceptable performance is a cumbersome task. As the size of the patch antenna increases with decrease in the frequency, appropriate techniques have to be adopted to design a patch antenna at low frequency. This paper presents a dual band transverse electric (TE) mode exited antenna that works well below 1 GHz. The principle of dual periodic artificial magnetic conductor (AMC) is the key for the dual band in this proposed antenna. The proposed antenna resonates at 515 MHz and 775 MHz with gain of 2 dBi and 4.5 dBi, respectively.
