An antenna array for wideband operation (up to 70%) is presented. The structure has low windloading area and consists of parallel printed circuit boards (PCB) with microstrip dipoles, feed network and metal fences placed between the PCBs. The low profile, low weight antenna array forms the main beam and three difference patterns for sidelobe cancellation. Experimental results are compared with calculations for both microstrip dipole and array 相似文献

The design and experimental results of a very wideband small printed dipole antenna array are presented. The impedance bandwidth (VSWR ⩽1.7) of the antenna, centred at 780 MHz, is 47%. In the frequency band 610-960 MHz, the designed antenna has a gain of 9.5-11.9 dBi, sidelobe level <-16 dB and front-to-back ratio <30 dB. The main features of the design are the use of parasitic elements to expand the frequency band and the application of a mesh frame to decrease the sidelobe level 相似文献
