“…The two conductor separated by dielectric material looks like a transmission line. So transmission line model can be used for mathematical analysis of proposed antenna [10] [11]. When excitation is given to antenna then because of fringing field the effective length of the patch is increase.…”

“…However, the 3-dB axial ratio (AR) bandwidths of these two antennas are relatively narrow. An E-shaped polarization reconfigurable patch antenna presented in [8] can achieve a 7% overlapped bandwidth while 10% bandwidth is obtained in [9]. The L-probe feeding structure used in [9], however, increases the complexity of the antenna.…”

Abstract-This paper presents a novel printed antenna which achieves wide bandwidth, high gain and reconfigurable circular polarizations. A loop antenna is printed on both sides of a dielectric substrate: a dual PIN diode loaded loop is printed on one side while a dual gap loaded smaller loop is etched on the other side. By controlling the on/off states of the PIN diodes, the polarization of the proposed antenna can be switched electronically to right-hand circular polarization (RHCP) or left-hand circular polarization (LHCP) over a wideband frequency range. A prototype is fabricated and measured to verify the performance of the antenna. The measured results indicate that the antenna can achieve an impedance bandwidth of over 30%, and a 3-dB axial ratio (AR) bandwidth of 12.7% and 14.9% for RHCP and LHCP, respectively. The measured gain is around 8 dBic for LHCP state and 7 dBic for RHCP state. Due to advantages of wide overlapped bandwidth, simple feeding structure and high gain, this antenna is promising for applications in dual-CP wireless communication systems.

“…Implementing polarization reconfigurability to increase channel capacity is also attractive in MIMO systems [1]. In recent years many reconfigurable microstrip patch antennas [2][3][4], slot antennas [5][6] and monopole antennas [7] were proposed to achieve polarization, frequency and pattern reconfiguration. However, to the best of our knowledge, only four polarization reconfigurable printed monopole antennas are reported from which, only two are circularly-polarized (CP) [8][9].…”

Abstract-A simple polarization reconfigurable printed monopole antenna is proposed for wireless applications. Conducting strips are used to connect to the ground plane providing the necessary additional modes for circular-polarization. Linear-polarization, right hand or left hand circular-polarization can be realized using only two PIN diodes, which connect to the ground plane, minimizing their effect on radiation characteristics. The mechanism is described, and key antenna parameters are studied and optimized. The antenna is prototyped and tested for all polarization configurations Index Terms-Monopole antennas, polarization reconfigurable
