A New Metamaterial Printed Microstrip Yagi -Array Antenna for ISM band Applications

A Novel Wide-band Microstrip Yagi-uda Array Antenna for Wlan Applications

This paper presents a design of Wide-Band Microstrip Yagi-Uda antenna with high gain and high front to back (F/B) ratio. Numerical and measured results of our design show more than 18 dB front to back ratio at 5.5 GHz and no backward radiation at 5.2GHz. An impedance bandwidth of 22.05% was achieved around 5.5GHz. The antenna gain (10–12.4 dBi) can be varied to be suitable for various applicati...

Analyze a various specifications of Microstrip Patch Array Antenna Using Beamforming Method for ISM Band Applications

In this paper, the design of 4x4 smart antenna array antenna along with the butler matrix network which can be used for beamforming (pointing an antenna array). Unlike the conventional schemes where an array of microstrip patch antennas are used, the radiation becomes omnidirectional and therefore the power losses are more. In the proposed design, the designed antenna is operating at the freque...

A New Dual Band Printed Metamaterial Antenna for RFID Reader Applications

Received Feb 12, 2017 Revised Jun 23, 2017 Accepted Aug 5, 2017 In this paper, we present a new dual band metamaterial printed antenna for radio frequency identification applications. The proposed antenna consists of two L-shaped slot in the radiating element for dual band operation and a complementary split ring resonator etched from the ground plane for size miniaturization. This antenna is d...
