CIRCULARLY POLARIZED PATCH ANTENNAS ANTENNA ARRAYS AND DEVICES INCLUDING SUCH ANTENNAS AND ARRAYS

摘要

For use in a wireless network , an apparatus for use in a wireless network includes an antenna having a first patch element with two opposite corners truncated and 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 a second patch element with two opposite corners truncated and 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.
