Square Microstrip Antenna (SMA) with rectangular notch at its radiating side is designed and analysed for its dual frequency characteristics. Electromagnetic band gap (EBG) structures are employed by etching holes at the bottom side of patch. The EBGSMA also contains a reflector plane which is placed at 8.5mm distance from the patch. The variation in the properties of Square Microstrip Antenna (SMA) with rectangular notch having different patterns of EBG is studied.

Objectives: A novel quantum binary voting scheme that uses only single qubits is proposed. Specifically, the protocol is designed by modifying a single qubit based scheme for controlled deterministic secure quantum communication. Methods/ Statistical Analysis: The security of the protocol is analyzed over some specific attacks. Further, qubit efficiency of the protocol is also calculated. Findings: It is established that in the case of binary voting, the proposed single qubit based quantum voting protocol is more efficient than some of the recently proposed protocols for binary voting. Further, it is also shown in some of the recent papers that the original single qubit based quantum secure direct communication scheme that has been modified to design the proposed quantum voting scheme is less affected than corresponding multiqubit based scheme. This further establishes the relevance of the present results. Application/Improvements: As the proposed scheme does not require complex quantum resource like entanglement & qudits, it seems to be experimentally realizable using the available technology.Keywords

This paper adumbrates novel meta materials (MTMs) named 'C' shaped Pair (CSP) and Closed Ring Pair (CRP). An soft HFSS has been used to design and analyse the CSP MTM having FR4_epoxy (εr=4.4) as substrate material and CRP MTM having Mylar (εr=2.89) as substrate material. Electric and Magnetic properties of MTMs have been used to mathematically demonstrate the negative permeability and permittivity region. Nicolson Ross Wier (NRW) method has been used to retrieve the material parameters from transmission and reflection coefficient. Nearly 5% deviation has been obtained between the results from Finite Element Method (FEM) based An soft HFSS and transmission line theory based quasi-static regime.Keywords

Conformity of the antenna to the mounting surface is the most essential requirement of modern communication system, whether it be antenna mounted on vehicles or airborne applications primarily due to the aero dynamical advantages of such antennas. In this paper we present the analysis of a inset microstrip line fed patch on cylindrical substrate with electrically small radius of 0.1 times free space wavelength. We try to analyse the effect that the bending has on the resonant frequency, inset length of the feed line of the patch antenna. We present the design dimensions, S11 & Radiation pattern results for the designed conformal patch antenna.Keywords
