Abstract
For use in a wireless network, an apparatus for use in a wireless network includes an antenna having (i) a first patch element with two opposite corners truncated and (ii) a first microstrip line connected to a first side of the first patch element and configured to feed the first patch element. The first microstrip line forms an angle of substantially 45° with the first side of the first patch element. The antenna could also include (i) a second patch element with two opposite corners truncated and (ii) a second microstrip line connected to a side of the second patch element. The second microstrip line could form an angle of substantially 45° with the side of the second patch element. The patch elements could be series-coupled and form an antenna array. One patch element could represent a host patch element, and another patch element could represent a parasitic patch element.
