Slot Antenna Uses Dual Polarization | Microwaves & Radio As will be shown, however, it is possible to obtain broadband frequency operation with a dual-polarized-antenna design. The antenna, excited by two coaxial-line feeds, is composed of four T-shaped slots and four cross-shaped slots in the radial directions of a circular patch. Slotted Rectangular Microstrip Antenna for Dual Band … technique is used to design both the antennas. First, the design parameters for single element of rectangular patch antenna is calculated from the transmission line model equation and then the antenna design is extended to operate in dual band using the slots at …

The antenna is intended for both near and far fields Radio Frequency Identification (RFID) applications. The meander dipole tag antenna geometry modification is designed for frequency bandwidth increasing.
