Multiband Microstrip Patch Antenna for Communication and Navigation Applications

Abstract

With the rapid development of satellite communication, satellite navigation, and wireless communication systems, multiband antennas are widely studied for military and commercial applications. To cover multiple frequency bands, we designed a multiband and wideband microstrip patch antenna with four multiple concentric rings fabricated on upper layer. Meander, fractals, and feeders covered with magnetic material could be beneficial to achieving relatively lower frequency bands. The novel layout optimizes the space utilization of the antenna and excites at multiple resonant modes. As a result, the proposed structure could obtain 7 operating bands of 0.
