However, in [20], [25], PIN diodes connected on a microstrip slot antenna are used to achieve the purpose of reconfigurable band notching.

Polarization Reconfigurable HMSIW U-Slot Antenna polarization reconfigurable microstrip antenna using PETs was proposed. Either RHCP or LHCP could be obtained by changing the bias-voltage of two PETs at 5.8 GHz. In this paper, a polarization reconfigurable half-mode substrate integrated waveguide U-slot antenna radiating LHCP or LP wave is proposed. Its concept is simple and based on a Reconfigurable antenna - Wikipedia Reconfigurable antennas differ from smart antennas because the reconfiguration mechanism lies inside the antenna, rather than in an external beamforming network. The reconfiguration capability of reconfigurable antennas is used to maximize the antenna performance in a changing scenario or to satisfy changing operating requirements.

A novel reconfigurable antenna is presented in this paper. The antenna is capable of radiating either linear, left-hand circular, or right-hand circular polarization depending on the status of two switches. It has a radiating slot of the "cusp" shape. This slot supports two orthogonal magnetic current modes. Two perturbations are introduced at specific locations in the slot. A reconfigurable circularly polarized microstrip antenna ... This letter describes a square patch antenna with a switchable circular polarization (CP) sense. The proposed antenna has four L-shaped slots on the ground plane, and the CP radiation can be generated by current perturbation due to the slotted ground plane. ... / A reconfigurable circularly polarized microstrip antenna with a slotted ground ...

Apr 27, 2015 · Abstract: This paper proposes a reconfigurable multiband extended U-slot antenna with polarization diversity for wireless applications. The antenna is able to switch among linear polarization (LP) and left-hand (LH) and right-hand (RH) circular polarizations (CPs) for 2.4-/5.8-GHz wireless local area network (WLAN) systems.
