چکیده
An ultracompact self-triplexing antenna realized on a substrate-integrated rectangular cavity (SIRC) is discussed in this study. The proposed structure employs two L-shaped slots and an inverted U-shaped slot to radiate at three independent operating frequency bands. Three 50-ohm microstrip feed lines were used excite the radiation these slots. was individually tuned using size. placement size designed having mind considering obtaining one or more bands below SIRC cutoff frequency, which had advantage of enabling High port isolation achieved by applying ports orthogonally remaining ones, created weak cross-coupling channel. A lumped-circuit model examine operation. presented design has been prototyped experimentally validated with measured frequencies 1.92 GHz, 4.43 5.25 GHz for GSM, 5G, WLAN applications, respectively. isolations are better than 32.4 dB according both EM simulations measurements. Meanwhile, gain 4.3 dBi all

Reconfigurable MIMO Antenna Design with High Isolation using Metasurface
In this paper, a frequency reconfigurable multiple-input-multiple-output (MIMO) antenna has been described. The idea of the design is to form reconfigurable MIMO antenna by the development of two-port antenna that are identical to each other and pin diodes are used to achieve the frequency reconfigurability. The design of the canonical element consists of compact folded slots with one pin diode...
متن کاملBroadband Dual Polarized Space-Fed Antenna Arrays with High Isolation
This paper presents a novel design of dual polarized space-fed antenna arrays with broad bandwidth and high isolation between two orthogonal ports. The dual polarized space-fed antenna arrays are designed with bottom radiating element electromagnetically coupled to two orthogonal open microstrip lines and top parasitic elements excited by the radiation from bottom radiating element, without any...
متن کاملA Single-Layer Wideband Dual-Polarized Antenna with High Isolation
A single-layer wideband printed antenna for dual-polarized applications is proposed in this paper. Two orthogonal linear polarizations are achieved by adopting a hybrid feeding technique. The horizontal polarization is excited by an aperture-coupled microstrip feed line while the coplanar waveguide (CPW) feed line is responsible for the vertical polarization. Measurements demonstrate a fairly w...
متن کاملWideband Planar Inverted-F MIMO Antenna with High Isolation
A wideband planar inverted-F MIMO antenna with high isolation is proposed in this letter. The proposed MIMO antenna consists of two back-to-back planar inverted-F antennas and a forkshaped decoupling stub. The two planar inverted-F antennas are merged together with a shorting strip connected to the ground plane. In order to enhance the isolation, a fork-shaped decoupling stub connected to the g...
