Abstract :
The design of a single-layer dual-frequency rectangular microstrip antenna using a single probe feed has been demonstrated by Chen and Wong (see Microwave Opt. Technol. Lett., vol.11, p.83-4, 1996). In this dual-frequency design, the two operating frequencies are mainly determined from the patch dimensions and the substrate parameters, and the feed position is selected such that the TM/sub 01/ and TM/sub 10/ modes are excited at the first two resonant frequencies. We report the design of a two-element dual-frequency array (for 1.9 and 2.45 GHz) using the single-feed dual-frequency rectangular microstrip patches. Experimental results for the characteristics of such a dual-frequency antenna array are presented and discussed.
