This proposed work introduces the structure of frequency and pattern reconfigurable patch antenna. This proposed design comprises of a hexagon patch antenna with four oblique slits, two longitudinal and two latitudinal slits. Four PIN diodes are used to enable frequency and pattern reconfiguration in the longitudinal and latitudinal slits. The operating frequencies of the proposed reconfigurable antenna are 4.25, 5.65, 6.8, and 8.2 GHz and have a pattern slope of ?30°, 0°, +30°, and 180°. The pattern is reconfigurable in four directions without any servo system. The designed antenna is fabricated, and its performance is proved using quantifications. Experimental results have less than 15% error with the simulated results. This antenna is used for C‐band applications. 相似文献
