Abstract :
A design using an inclined-slot-coupling feed for dual-frequency operation of a rectangular microstrip antenna with a cross-slot is described. Results show that, for a given dual-frequency operation, a reduction in antenna size of ~40% can be achieved by using this design. Also, the frequency ratio of the two frequencies is very slightly affected by the cross-slot length, and mainly determined by the aspect ratio of the patch, making the design simpler and easier to implement
