Circularly Polarized Microstrip Fed Antenna for Dual Frequency
Abstract: Abstract: The presented antenna is designed for achieving dual frequency characterized circularly polarized behavior. The achievement of dual frequency is done by coupling of the microstrip feed line arrangement with the annular slot shaped with four unequal arms type of slot structure on the patch. The Reflection coefficient, pattern of radiation of the antenna and the Axial ratio are simulated. The impedance bandwidths obtained for lower of (RHCP) is 25% …

A Review On A Compact Dual Polarized Antenna Array
Abstract: A compact dual-polarized antenna array for low-cost millimeter-wave (mm Wave) applications is proposed in this article. Utilizing a patch antenna with two orthogonal feeds positioned horizontally and vertically, a dual linear polarization antenna can be created. Two ports—a vertical port and a horizontal port—make up the suggested design. The antenna produces horizontal polarization by stimulating the horizontal port. The antenna produces vertical polarization by stimulating vertical port. With the higher …
