An Optimized Design Procedure of Slot-Coupled Dielectric Resonator Antennas
Author: Mostafa Hefnawi

Acceptance Date: 01/05/2017

This paper presents an optimized design procedure of a slot-coupled cylindrical dielectric resonator antenna. The technique exploits an equivalent circuit of the resonating antenna to significantly reduce the number of full-wave EM simulations. The target values of the equivalent circuit elements are determined from the desired specifications such as bandwidth, center frequency and in-band return loss level. Design curves relating the elements of the equivalent circuit to the physical dimensions of the antenna are first established and then subsequently used to determine the parameters of the structure. The proposed approach is validated by comparing its scattering parameters to the ones obtained from measurements and from HFSS (High Frequency Structure Simulator).

Acceptance Date: 03/20/2017

A flexible compact Multi-input Multi-output (MIMO) T-shape monopole antenna with negative permeability (MNG) unit cell working at 4.9 GHz is presented. The proposed printed monopole antenna is suitable for homeland security, public safety service, personal area network (PAN) and WLAN/On-Scene Incident command applications. MNG unit cell is integrated with the structure to decrease the mutual coupling effect inherent with MIMO system. The achieved results show that there is a good enhancements in mutual coupling reduction -11.1 dB and boresight gain 2.2 with 14.1% impedance bandwidth and 71% efficiency for 0.29λ as a separation distance between the MIMO antennas.

Enhancement of Functional properties of antenna with Application of DGS
Soumya Ranjan Mishra, Sheeja K L

Acceptance Date: 04/25/2017

A Simple and easy Defected Ground Structure (DGS) is proposed. The objective is to achieve suppression of cross polarization resulting in improved polarization purity in radiated fields. For this purpose, firstly rectangular and circular patch antennas were taken into consideration, with the same geometry of DGS. In the next configuration, a circular patch antenna was incorporated with a rectangular shaped DGS. The employed DGS appears to be highly efficient to enhance the functional properties of the antenna, especially suppressing Cross Polarization in the H-plane. Rectangular microstrip patch antennas have been designed with different aspect ratios and show 10 dB suppression of Cross Polarization in H-plane. Similarly, a circular patch antenna inspired by rectangular and arch shaped DGS’s has been studied. The effect of total engraved area and the gap between DGS‟s on the resonant frequency was examined and presented.  

Comparison Study and Effect of Cut and Un-Cut Rectangular Spiral Metamaterial on Properties ofMicrostrip Patch Antenna
Asaad  M.  Jassim  Al-Hindawi and Chnar Hussein Aziz

Acceptance Date: 02/02/2017

The present paper investigates the effects of uncut and cut single rectangular spiral metamaterial unit cells on the performance of a microstrip antenna. A studied microstrip patch antenna is designed to operate at 2.4GHz and is fed by a microstripline of a rectangular shape. Initially, the designed antenna is covered by unit cells of a single uncut spiral metamaterial. The second antenna design is covered by different cuts in the spiral cell. These spiral cut shapes are chosen separately to be horizontally, vertically, diagonally and combinations of them. The antenna design of uncut cells leads to an increase in the number of resonance frequencies while the antenna gain is decreased. Meanwhile, the design of the antenna with cut cells leads to an increase in the number of resonance frequencies yielding to a better S11 and an increase in the antenna gain compared with those of the antenna of uncut cells. The above results are obtained using HFSS simulator.

Nancy Ghattas, Atef M. Ghuniem, Sherif M. Abuelenin

Acceptance Date: 07/11/2017

Dielectric rod antennas are promising candidates to be used in millimeter wave band wireless communications. The optimization of a patch-fed dielectric rod antenna design at millimeter wave band is presented in this work. This design is composed of simple dielectric rod antenna made of low cost Teflon with relative permittivity of 2.1 that is fed by a rectangular patch antenna. Compared to the conventionally used tapered dielectric rod antennas, this configuration is capable of producing higher gain for a given antenna length. The design is optimized to achieve gain up to 17.5 dBi and impedance bandwidth up to 4.4 GHz at 60 GHz. A 4-element array is proposed to increase the gain up to 21 dBi. Simulations are performed using CST microwave studio, and their results are presented.
