An artificial magnetic conductor (AMC)-based patch antenna with a low profile is developed for wireless devices in IoT-based healthcare systems. The proposed comprises two pairs of circular-shaped patches slots and dual-band 4 × array AMC reflectors zero-degree reflection responses to enhance the antenna's radiation performance. For 2.45 GHz ISM 5.4 WLAN bands, has dimensions 0.44λ0 0.52λ0 0.01...

The demand of small, lightweight and high effectiveness antennas has increased significantly with the development communication technologies. Microstrip patch (MPAs) are one most widely used types antenna that can satisfy these requirements. MPAs have numerous benefits, including tiny size weight, ease fabrication, inexpensive. In addition to advantages, also some drawbacks such as limited band...

This article presents compact and novel shape ring slotted antenna array operating at mmWave band on central frequency of 28 GHz. The proposed structure designed 0.256 mm thin Roggers 5880 is composed a patch with square slot etched the top mid-section partial ground plane. Through optimizing parameters high bandwidth 8 GHz achieved ranging from 26 to 32 simulated gain 3.95 dBi total efficiency...

A circular polarized patch antenna for UHF RFID tag-based sensor applications is presented, with the circular polarization (CP) generated by a new antenna shape, an asymmetric stars shaped slotted microstrip patch antenna (CP-ASSSMP). Four stars etched on the patch allow the antenna's size to be reduced by close to 20%. The proposed antenna is matched with two RFID chips via inductive-loop matc...

In this letter, we present a systematic approach to design compact dual-mode monopole-like patch antenna using characteristic mode analysis (CMA). The modal of slotted circular structure incorporating new shorting pin loading technique is presented. To achieve with the wideband operation, it demonstrated that first two significant modes patterns are most suitable ones for excitation. Based on c...

This study presents a compact ultra-wideband (UWB) antenna fed by coplanar waveguide (CPW) with huge bandwidth for the demands of modern wireless communities. To overcome some technical limitations employed substrate and UWB design, slotted patch resonator was used to create simulate this based on Locked-Key topology. It has been printed 1.5 mm-thick FR4 dielectric constant 4.4. A feeder charac...
