To achieve dual frequency operation for wireless body area network (WBAN) applications, a hybrid dual-band dielectric resonator antenna with serpentine slot fed by a microstrip line is proposed. The proposed antenna structure consists of cylindrical dielectric resonator and serpentine slot resonator. The serpentine slot is etched on the ground plane of the dielectric resonator antenna (DRA). By...
Yong-Woong Jang 33 A numerical simulation and an experimental implementation of T-shaped microstrip-fed printed slot array antenna are presented in this paper. The proposed antenna with relative permittivity 4.3 and thickness 1.0mm is analyzed by the finite-difference time-domain (FDTD) method. The dependence of design parameters on the bandwidth characteristics is investigated. The measured ba...
Wide Band CPW-fed Circular Patch Antenna with Tapered Ground Plane Maryam MAJIDZADEH* Changiz GHOBADI Electrical Engineering Department, Urmia University, Urmia, IRAN [email protected] A novel Co-Planar Waveguide (CPW)_ fed antenna is presented for Ultrawide Band (UWB) applications. The main body of the antenna comprises of a simple circular patch and a ground plane with tapered ste...
This paper presents the electrically small U-slot loaded circular microstrip patch antenna with Complementary Split Ring Resonator (CSRR). The technique of U slot loading is used for operating antenna in dual band and CSRR technique to make antenna compact and CSRR for compactness is used. The simple circular patch antenna resonates at 5. 71 GHz with return loss of -11. 38 dB. The proposed ante...
This work designs a 60 GHz rhombic patch array antenna with high gain, low sidelobe level (SLL), and reduced area. consists of eight linear serial arrays varying number patches. A slot-coupled center-fed structure substrate-integrated waveguide (SIW) is designed to simplify the complex feed network required for direct excitation planar reduce insertion loss. The configuration utilizes quantity ...
A uniformly spaced comb taper slot antenna array is proposed for directional ultra-wideband (UWB) applications. The UWB array consists of four identical comb taper slot antennas, a mutistage with four-way microstrip UWB power divider, and four identical coaxial cable lines. A maximum gain of 15.5dBi within the band is obtained when the element separation is properly selected. The uniform spacin...
This paper presents a patch loaded slot antenna for super wideband (SWB) application. To obtain SWB characteristic, the proposed geometry combined rectangular and an overlying excited by trident shaped microstrip feed. It is observed that hybrid nature of effectively enhances impedance bandwidth up to 120%, combining resonance both slot. Besides, it investigated after converting conventional ta...
A novel frequency reconfigurable slot antenna is designed for cognitive radio system. In cognitive radio system the two antennas are required one is a wideband antenna and another is frequency reconfigurable antenna. In this work a frequency reconfigurable slot antenna is designed between the switchable frequency range i.e 7.347.96 GHz at eight different frequency band and capable to operate si...
A Dielectric Resonator loaded Substrate integrated waveguide cavity backed slot antenna (SIDRA) is proposed for two slot polarizations and orientation. A SIW-fed cylindrical DRA using rectangular slot is used for obtaining bandwidth of about 5% at 6.15 GHz. For enhancing bandwidth, a plus shaped slot with bandwidth of about 8.80% and gain of 3.7 dB is proposed. The proposed antenna represents S...
