RISA New Empirical-Physical Method for Calculation of Path Loss for Fixed Wireless Access in Suburban Areas
In this paper a new empirical-physical method for calculation of path loss in the fixed wireless access in suburban areas is proposed. It is shown that this method has a relatively good accuracy for high transmitter antennas. ...
Epsilon-Zero Resonance Antennas with Modified Unit Cells
In this paper new epsilon-zero resonance (EZR)antennas using epsilon negative (ENG) transmission line

Resonance Antennas Based on Substrate Integrated Waveguide
Two types of antennas based on the open-ended substrate integrated waveguide (SIW) resonator are presented and investigated in this study. To understand the operation mechanism of these antennas, the open-ended SIW resonator ...
An Exact Formulation for Dual-band Composite Right/Left Handed Transmission Line Design
This article presents an exact formulation for dual-band composite right/left handed (CRLH) transmission line (TL) design. Because of using an approximation, the previously introduced formulation for design of such TLs is ...
A wideband 45° inclined linear polarization travelling-wave slot array antenna with broadside radiation pattern
In this paper a new slot array antenna with 45° inclined linear polarization for application in collision avoidance systems is presented. The proposed antenna is fed by a travelling wave and hence, in contrast with standing ...
