Modern RFID system demands for low cost and low profile antennas. Microstrip antenna offers a potential solution meeting those requirements. In this paper a new antenna design using a inset fed that is suitable for high gain microstrip antennas is presented.
In meander line antenna the size of the dipole at given frequency is reduced by a factor that is proportional to the number of turns. The adjacent horizontal segments of the meander line antenna have opposite phase. The transmission line current neither contributes much to the radiated power nor produce losses. At the location where the current reaches maximum value at that point large amount of power...
In this paper, an inward scaled loop antenna (ISLA) is presented. It is created by successive scaling and rotating and fitting the scaled copies of a wideband loop antenna (WBLA) in the empty space available in it. The overall size of the antenna remains the same as that of the WBLA. The advantage of an ISLA is its improved input performance as compared to the WBLA. Impedance bandwidth of the order...
