Stacked Common Mode Power Combining Patch Antenna For LINC Transmitter

Abstract

A new stacked antenna that enhances the operating frequency bandwidth of an integrated power combining patch antenna is presented in this paper. A coupled-parasitic patch is used for stacking, so that the balanced mode of the antenna is preserved. Around 10% (return loss <¿10dB) bandwidth has been achieved for both the differential and common mode.
