Dual-band dual polarization microstrip antenna

Progress in dual-band dual-polarization shared-aperture SAR antennas

“…The requirements for antennas are varied in different missions. For the former case, an omni-direction pattern is usually required while for the latter two, the reflector antennas are preferred where a horn or a small patch array may be used as the feed [15,16].…”

Shared-Aperture Multi-Band Dual-Polarized SAR Microstrip Array Design

“…The perforated structure mainly includes perforated-patch/patch [3,4], ring/patch [5][6][7] and cross-patch/patch [8]. The interlaced layout includes interlace patch with dipole/slot [9][10][11] and interlaced slot with slot/dipole [12][13], etc.…”

DBDP SAR Microstrip Array Technology

“…The requirements for antennas are varied in different missions, and thus the designs are different, especially for the latter two where the reflector antennas are preferred while a horn or a small patch array may be used as the feed [10,11]. This paper emphasizes the DBDP antennas for SAR application.…”

“…One example is the L/C-band array of interlaced L-band perforated cross-patches with C-band patches, whose top view and cross section are shown in Fig. 16 [10]. The LF perforated cross-patch on the top layer is interlaced and rounded by 9 HF patches located on another substrate behind it to form a unit cell.…”
