摘要：
A dual band double slot loaded microstrip antenna with a diagonal coaxial feeding is proposed. Rectangular patch is used as radiator over which two narrow slots are created. These slot and feed position make antenna both frequency and polarization reconfigurable. The bandwidth of this slotted antenna is 550 MHz and 180 MHz at 4.0 and 4.9 GHz respectively. This bandwidth is sufficient for many applications like satellite and radar communication. The antenna is analyzed and simulated using HFSS V. 17.0. The 10: 1 gain bandwidth of the simulated antenna with respect to center frequency is 12.5% at 4.9 GHz and 4.7% at 4 GHz. The proposed work provides 7.8dBi gain at frequency 4.9 GHz and 7.1dBi at 4 GHz. The proposed antenna provides circular polarization (both LHCP and RHCP). This antenna having an overall dimension of 60 x 60 x 3.8 mm(3) and the dimension of slots created over patch is 18 x 1 mm which is very compact compared to the conventional antenna.
