In this paper, the design of a multi-band circularly polarized stacked microstrip antenna for low earth orbit (LEO) satellite communications and precise global positioning system (GPS) is proposed. The microstrip antenna for multi-band frequency is constructed by stacking two different square patches and circular polarization is obtained by different approaches. The top patch has a pair of truncated...
A novel compact metamaterial antenna for wireless area local network (WLAN) applications is proposed in this paper. The antenna is fed by a co-planar waveguide (CPW). Size reduction of the antenna is achieved thanks to the use of a modified conventional composite right/left handed (CRLH) model without vias. As a result, the antenna demonstrates a good size reduction in comparison with the conventional...
