A polarization reconfigurable antenna using metasurface superstrate is proposed in this paper. The proposed antenna consists of a planar coupling slot with an array of metallic rectangular patches with PIN diodes which can be view as a reconfigurable metasurface superstrate, and a DC bias controlling circuit. When the PIN switches are OFF, the antenna can produce left-hand circular polarized (LHCP)...
A wideband and low-profile circularly polarized antenna using metasurface for WLAN or satellite communication applications is proposed. The proposed antenna consists of a planar slot coupling antenna with an array of metallic rectangular patches which can be viewed as a metasurface. The metasurface is utilized to adjust axial ratio (AR) for circularly polarized radiation and the slot is angled at...
A new frequency and pattern reconfigurable antenna is proposed in this paper. Both frequency and pattern reconfigurations are effectively realized by using the microstrip double fed ports and four PIN diodes on the annular slot. At the low frequency band (1800MHz) and high frequency band(2400MHz), the antenna has four different patterns which are almost omnidirectional scanning and can be used to...
A novel method of designing broadband microstrip antenna is proposed in this paper. By embedding a pair of Cross-shaped slots placed close to the non-radiating edges of a microstrip patch and adding an air layer between the substrate and the ground, the broadband character can be achieved. What's more, the formulas for calculating the two resonant frequencies have been experimentally deduced. Employing...
