✦ Synopsis

By embedding a pair of comb-shaped slots close to the nonradiating edges of a rectangular microstrip antenna, a no¨el dualfrequency operation of microstrip antennas using a single probe feed is proposed and experimentally studied. The two operating frequencies ha¨e the same polarization planes and similar broadside radiation patterns. By ¨arying the length and number of the branches of the comb-shaped slots, the proposed antenna pro¨ides a tunable frequency ratio from about 1.07 to 1.29. Details of the antenna design and experimental results are presented and discussed.

No¨el design of a dual-frequency triangular microstrip antenna with a V-shaped slot is proposed and experimentally studied. By selecting suitable dimensions of the V-shaped slot, dual-frequency operation with the frequency ratio ranging from 1.488 to 1.834 has been obtained using a single probe feed
