Serial Aperture-Coupled Dual Band Circularly Polarized Antenna

In this innovative method of producing circular polarized (CP) wave, we present a serial feed line which couples diamond-shaped slot to ring and cross-slot to patch. The feed line is used to feed the two parts in series. Then, the structure can easily be operated as a dual band circularly polarized...

Description
Summary:In this innovative method of producing circular polarized (CP) wave, we present a serial feed line which couples diamond-shaped slot to ring and cross-slot to patch. The feed line is used to feed the two parts in series. Then, the structure can easily be operated as a dual band circularly polarized antenna to cover both 0.915 GHz and 2.45 GHz bands. Experimental results show that the proposed antenna has good circular polarization characteristics.
