Abstract :
Novel dual-frequency operation of a single-feed equilateral-triangular microstrip antenna with a pair of spur lines is demonstrated. The two operating frequencies are of the same polarisation planes and, by varying the spur-line length, the frequency ratio of the two operating frequencies is tunable in the range of ~1.2-2.1. Details of the antenna design are described, and experimental results are presented and discussed
