Compact rectangular microstrip patch antenna for dual band application

“…The interlaced radiator concept uses cavity-backed annular slots as radiators used in [2] for both S and X bands. A coaxially-fed singlelayer three overlapped rectangular patches (C and X band) dual-polarized antenna is proposed in [3]. Different perforated elements are presented and discussed in [4][5][6].…”

The design of triple-band C/X/Ku dual-linear polarized microstrip antenna single element and 1x2 sub-array is simulated and presented. The triple band is designed as one antenna for a dual-band C/X with dual-linear polarization and a shared aperture antenna for single Ku-band dual-linear polarization behavior. Four different shapes of feeding ports for the two antennas provide good isolation among all frequencies at both polarizations. The designed antenna exhibits stable frequency response at ON/OFF states for either single/dual frequency selection or Horizontal/Vertical polarization. The results show fair radiation pattern with high gain. The performance of the designed antenna was computed using HFSS 11.1 . The antenna is designed to fulfill the Synthetic Aperture Radar (SAR) requirements, where multi-band dualpolarization is required.

Abstract-Microstrip patch antenna has been designed and developed for Unmanned Aerial Vehicle based Synthetic Aperture Radar (UAVSAR). This antenna operates in C-Band at the frequency of 5.3 GHz with a bandwidth of 80 MHz. The radiation patterns of the antenna were specified to provide a desired scanned area for UAVSAR. The UAVSAR antenna was designed in the form of combination of 3 subpanels to allow dual operating mode (single antenna or dual antenna) selection. Two feed points are provided to the feeding network of each subpanel to reduce undesired power loss. The developed antenna prototype meets the performance requirements of UAVSAR system. It shows promising results in the UAVSAR flight mission conducted in Mersing area, Malaysia for both operating modes.
