A new topology to reconfigure the radiation pattern in feedback-type oscillating active integrated antenna (AIA) is proposed and demonstrated in this letter. The proposed active antenna consists of an array of two patch elements as a passive radiator integrated with an active device to form a feedback-type oscillating active antenna. Three states (main beam at θ = 0°, +30°, and −30°) of the broadside...
This paper presents a low profile microstrip patch antenna for next generation 5G devices. The proposed patch antenna has a compact structure of 20mm × 20mm × 1.6mm including the ground plane, which is suitable to be used in handheld devices. The antenna resonates at 10.15 GHz covering 5G frequency band. The proposed design provides a gain of 4.46dBi and the radiation pattern is omni-directional....
In the recent years, the demand for low profile, low cost and high performance antennas has increased due to rapid development of communication systems. This paper presents a parametric study on ground slotted microstrip patch antenna for X-band applications. In order to reduce the size of the proposed antenna, slots have been introduced on the patch and ground plane. Therefore the total size of the...
A novel compact size triple-band microstrip antenna with and without fork like electromagnetic band gap (EBG) structure is proposed for wireless mobile communication system. The proposed antenna consists of two simple Y-slots, integrating with compact size fork like EBG structure. The overall dimension of the proposed antenna is 20.5 × 23.5 × 1.6 mm3. The results show that the presented antenna cover...
A stacked microstrip antenna with H-shaped parasitic patch for multiband applications is presented in this paper. The antenna designing is done by using HFSS simulation tool and feeding by microstrip feed line (50Ω). In the absence of slot a conventional rectangular microstrip patch antenna is also considered for confirming the validity of designed antenna. This conventional antenna design found to...
Wide band truncated rectangular micro strip antenna with slot loaded stacked patches and defected ground plane structure is presented in this paper to increase the bandwidth. By inserting slot in the ground plane the bandwidth of the stacked truncated rectangular micro strip antenna is improve by twice. The bandwidth before adding the slot in the ground structure was 29.7% whereas after adding the...
This paper presents an experimental investigation of inclined slot loaded rectangular micro strip antenna that has been carried out for dual -band operation with the help of a single probe feed for Global Positioning Satellite (GPS) applications. In this case, two resonant frequencies 1.57 GHz and 1.22 GHZ occur. It is observed that the VSWR and RETURN LOSS of two resonant frequencies can be changes...
In this paper, a robust stochastic algorithm called Particle Swarm Optimization (PSO) is used to optimize resonant frequency of circular microstrip patch antenna. A modified formula for resonant frequency is presented using PSO. The obtained results using particle swarm optimization has been compared with experimental and theoretical values of previous papers. The results were in good agreement with...
A dual-band characteristic of single layer stacked rectangular microstrip antenna is experimentally studied. The variations of the length and width of the stacked rectangular patch antenna has been done and found dual resonance with increasing lower resonance frequency and almost constant upper resonance frequency with increases of the length & width of rectangular microstrip antenna. The VSWR...
