Circularly Polarized Single-Layer Microstrip Reflectarray Fed With a 2x2 Microstrip Patch Array

Circularly Polarized Microstrip Patch Antenna with T - Shaped Slot

In this paper a new geometry of circularly polarized patch antenna is proposed with improved bandwidth. The radiation performance of proposed patch antenna is investigated using IE3D simulation software and its performance is compared with that of conventional circular patch antenna. The simulated return loss, axial ratio and impedance with frequency for the proposed antenna are reported in thi...

Circularly Polarized Proximity-Fed Microstrip Antenna with Switchable Polarization Ability

14 Circularly Polarized Slotted / Slit - Microstrip Patch Antennas

In modern wireless communication systems, small circularly polarized microstrip antennas with good performance are desirable mainly at low microwave frequencies. The radio frequency identification (RFID) systems in the ultra-high frequency (UHF) band have gained much interest in many services [Finkenzeller2004]. The reader antenna is one of the important components in the RFID reader system and...

Multi Band Circularly Polarized Microstrip Patch Antennas for Mobile Communication

This paper represents a circularly polarized microstrip antenna for many kind of wireless communication applications. Circular polarization can be achieved with asymmetries. The emphasis is on to increase the bandwidth of the antenna. In this paper various kinds of techniques has been used to provide circular polarization like triangular slits inserted at the corners, corners of the patch are t...
