Abstract
An antenna featuring a pair of radiating elements. Each pair of radiating element is fed from the same input. Each radiating element is a stacked antenna made of feeding patch and radiating patch featuring cross recessed corners. Moreover, the corners of a radiating patch and the corners of its feeding patch are cut in opposite directions. The use of recessed corner patches result in improved cross-polarization. Improved cross-polarization leads to better isolation between radiating elements of an array antenna and to an antenna featuring improved isolation from its surroundings.
Claims7
At least one circular polarized antenna comprising:
- a feeding patch having cross recessed corners, and
- a radiating patch having cross recessed corners complementary with the recessed corners of the feeding patch.
A circular polarized stacked array antenna comprising:
- feeding patches having cross recessed corners,
- radiating patches having cross recessed corners, and
- at least one sandwiched cross-recessed corner patch,
- wherein the patches are arranged in such a way that every two following stacked patches are cut in the complementary corners.
