This paper presents a very compact, wideband, and enhanced-gain antenna for 5G applications. A simple single-layer millimeter wave (mm-wave) metamaterial lens (meta-lens) is used to improve the gain, aperture efficiency, gain bandwidth of slotted-patch over wide range frequencies from 25 GHz 31 GHz. The exhibits negative refractive index behavior, which attributed substantial enhancement around...

In this paper, a novel compact frequency-reconfigurable monopole antenna with switchable symmetric slot structure is presented. The frequency-reconfigurable capability of the antenna is achieved by using a switchable slotted structure on the ground plane. The designed antenna has a simple structure and compact size of 40X40 mm . The antenna, which supports most applicable frequency bands above ...

This paper proposed a radio frequency identification (RFID) Reader Antenna which operates on ISM band with frequency range from 902 to 928 MHz and bandwidth of the antenna is 58MHz. Antenna consist of rectangular patches on Rogers RO4360 substrate with microstrip feed line. Return loss of the antenna comes out to be about -39.98 dB on behalf of the frequency 907MHz. Gain of the proposed antenna...

Microstrip Patch antennas are very prevalent these days due to various attractive features possessed by them. Coplanar Waveguide (CPW) fed patch antenna has benefits of compact size, ease of fabrication and integration with other monolithic circuits. Moreover, the proposed design is very simple design fed with CPW feed. The proposed antenna performs dual band (1. 5 GHz and 7 GHz) operation with...

This paper presents the study on a slot-etched rectangular patch antenna directly fed by the 50 Ω semi miniature A-type (SMA) co-axial connector for wireless systems. The dual frequency behaviour by etching the slots on plane patch surface is studied experimentally. The proposed patch antenna has also achieved 28% compactness with a gain of 9.74 dB. Other antenna parameters such as antenna inpu...

A compact cross, circular and square shaped slotted microstrip patch antennas are designed for circularly polarized (CP) radiation. Asymmetric, cross-shaped slot is embedded along one of the diagonal axes of the square patch for CP radiation and antenna size reduction. The designed antenna is contrived by using RT-Durid 5880 substrate . The design simulation and optimization is done by ADS soft...

A novel miniature wideband rectangular patch antenna is designed for wireless local area network (WLANs) applications and operating for 5-6 GHz ISM band, and wideband applications. The proposed antenna gives a bandwidth of 4.84 to 6.56 GHz for S11<-10dB. The antenna has the dimensions of 20 mm by 15 mm by 0.8 mm on FR4 substrate. Rectangular slot and step have been used for bandwidth improvement.

This paper describes the design of H and T-Slotted Rectangular Microstrip Patch Antennas (RMPA) which resonates at a frequency of fo = 2. 4 GHz. The FR4 glass Epoxy with relative permittivity 4. 4 and height 1. 6 mm is used as substrate material. Antenna is fed by coaxial probe feed and simulated using HFSS. This antenna used to various wireless applications such as WiMAX, Wi-Fi, and Digital Mu...
