Dual polarized slot coupled planar antenna with wide bandwidth

By Author

The monopole antenna is modified using microstrip transition in the feedline and block with a triangular-shape slot on each side of the circular patch to produce wider impedance bandwidth with better return loss.

Slot Antenna Uses Dual Polarization | Microwaves & Radio ... Dual-polarized antennas have been realized by means of several different design approaches—for example, achieving high input-port isolation and wide bandwidth when using aperture coupling feeds. 1-6 But this type of antenna suffers from obvious cross-polarization radiation caused by higher-order-mode transverse currents, which degrades the ...

a limited AR bandwidth. The truncated edges antenna exhibits the best axial ratio but has reduced AR bandwidth [3]. Alternative research [11,12] has produced bent slot and wide slot antennas with parasitic patch. Single-fed wideband circularly polarized slot antennas have also been reported [8,13,14], but the acquired gain is only about 3.5dB.

To achieve wide bandwidth and high gain at 35GHz, four parasitic patches are located above the active element. The measured results show that the frequency bandwidth of S 11 less than -10dB covers 30-40GHz and the isolation between two polarization ports is higher … A broadband proximity-coupled dual-polarized microstrip

Slot Antenna Uses Dual Polarization | Microwaves & Radio While a variety of dual-polarized antenna designs have been developed for this purpose, 1-12 there is always room for improvement. With that goal in mind, the current researchers developed a novel dual-polarized broad beamwidth slot antenna with low cross-polarization and high isolation. A Wideband High-Gain Dual-Polarized Slot Array Patch A low-cost, easy-to-fabricate, wideband and high-gain dual-polarized array antenna employing an innovative microstrip slot patch antenna element is designed and fabricated. The design parameters of the antenna are optimized using commercial softwares (Microwave Office and Zeland IE3D) to get the suitable 𝑆-parameters and radiation patterns. CPW-fed ultra-wideband slot antenna with broadband dual A CPW-fed ultra-wideband slot antenna with broadband dual circular polarization is proposed, manufactured and measured. The measured results are basically the same as the simulated results. Furthermore, CP antenna has a very wide impedance bandwidth and 3 dB axial ratio bandwidth with good radiation and port isolation performance.
