A novel compact ring monopole antenna with double meander lines is proposed for wireless local area networks (WLAN) applications in IEEE 802.11b/g/a systems. The designed antenna, fed by a 50 Ω microstrip transmission line, is only 32 mm in height and 16 mm in width. By introducing a horizontal and a vertical branched strips to a closed rectangular strip ring, the proposed antenna can generate ...

A novel compact multiple-input-multiple-output (MIMO) antenna for portable ultrawideband (UWB) applications is presented. This antenna consists of two modified planar-monopole antenna elements with coplanar waveguides-fed printed on one side of the substrate. To enhance isolation and increase impedance bandwidth, a tree like stubs is placed on the ground plane at the 45 ̊ axis. The measured resu...

The design of a novel volcano smoke antenna for UWB indoor applications is presented. The design method is based on a general description for the geometry of UWB monopole antennas which is capable of producing most possible shapes for these antennas. It is also compatible with different optimization methods. In addition to a volcano smoke antenna, this method is used to design two optimized mon...

Since the FCC has announced to allow the unlicensed use of the industrial, scientific, and medical (ISM) frequency band by any potential users, wireless communications community has provided enormous opportunities for driving many wireless systems that can be communicated over short distances. For example, some practical applications are operated at the internationally available unlicensed ISM ...

A Printed monopole antenna with coplanar waveguide (CPW)- fed having circular shape patch to met the Ultra Wideband technology whose bandwidth is greater than 500MHz proposed in this article. To enhance co-planar ground plane plays a great role for frequency band which belong mid 5G spectrum. good radiation pattern usually 8shape can be achieved

A high performance monopole antenna fabricated using a folded wire line and metal patch as radiator is presented. A prototype of the proposed monopole antenna with a compact area size is implemented, and the multi-band WLAN antenna shows a wide operating bandwidth of about 530MHz and 3400MHz for low band and high band, bandwidth, making it easy to cover the IEEE 802.11a, IEEE 802.11b, IEEE 802....

A 2.4 GHz flexible monopole antenna fed by a coplanar waveguide (CPW) was presented on polyimide (PI) as the dielectric substrate, which fabricated in situ self-metallization. The technology does not depend expensive equipment or complex experimental environments, including hydrolysis, ion exchange, and reduction reaction. measurement results show that resonance frequency of proposed is 2.28 GH...
