This paper proposes the configuration of a dual polarized wide-band patch antenna system suitable for indoor mobile communication applications. This configuration consists of two patch antennas, which have different feed structures from classical patch antenna configuration. These antennas, which are separated by a thin absorber to have a good isolation, are fed independently to obtain dual polarization. The antenna structure is designed, simulated, manufactured and measured. The operation bandwidth spans 1900-2700 MHz covering Bluetooth, Wireless Local Area Networks (WLAN) and Universal Mobile Telecommunications System (UMTS) bands. The simulations show good agreement with the measurement results that the antennas have return losses higher than 15 dB, and the coupling between two antennas is below -20 dB within the operation band.


An Inverted L-Shape Fed Microstrip Patch Antenna for Mobile Communication
Secmen, Mustafa; Hizal, Altunkan (2010-09-30)
This paper proposes the configuration of a novel wideband patch antenna system suitable especially for indoor mobile communication applications. This configuration consists of an elevated patch antenna, which has different feed structure from classical patch antenna feed configurations that the antenna is fed by an inverted L-shape structure. The antenna structure is designed, simulated and manufactured in order to be used in mobile communication applications when used in pairs that its operation bandwidth ...
A Dual-Band Wide-Angle Scanning Phased Array Antenna in K/Ka Bands for Satellite-on-the-Move Applications
Kapusuz, Kamil Yavuz; Aydın Çivi, Hatice Özlem; Yarovoy, Alexander G. (2017-03-24)
This study presents the design of a dual-band cavity-backed phased array antenna with wide-angle scanning capability in K/Ka bands for the geostationary (GSO)-fixed satellite service (FSS). To reduce the losses and mutual coupling, a novel antenna element similar to the cavity-backed Strip-Slot-Air-Inverted-Patch (SSAIP) is proposed as an element of designed array of 81 elements. Wide-angle scanning up to 60 degrees is achieved at both frequency bands of the operation. The developed antenna is suitable for ...
An ultra-wide band low-SAR flexible metasurface-enabled antenna for WBAN applications
Yalduz, Husnu; Koc, Burak; Kuzu, Lokman; TÜRKMEN, MUSTAFA (Springer Science and Business Media LLC, 2019-08-09)
In this study, an ultra-wideband low-specific absorption rate (SAR) flexible metasurface-enabled wearable antenna is proposed for wireless body area network applications. The antenna and metamaterial (MM) structure were designed and analyzed using a commercial electromagnetic simulation software program which uses a finite integration technique solver. The antenna is designed and fabricated on a jeans textile substrate in the size of 58 x 80 x 1 mm(3). Moreover, MM reflector was designed on a felt textile s...
Design and analysis of ultra-wideband (UWB) printed monopole antennas of circular shape
Karadağ, Serkan; Aydın Çivi, Hatice Özlem; Department of Electrical and Electronics Engineering (2017)
This study proposes three microstrip line fed circular monopole antennas with ultra-wideband (UWB) characteristics, improved omnidirectional radiation pattern and WLAN (5 GHz-6 GHz) band notched characteristics for wireless and mobile communication systems. In this thesis, first, a microstrip line fed ultra-wideband ring monopole antenna with improved omnidirectional radiation pattern is designed, fabricated and measured. Two corners are tapered on the ground plane for increasing impedance bandwidth. In ord...
A Hybrid Antenna Element for Travelling Wave Dual-Plane Monopulse Slotted Waveguide Arrays
Gültepe, Gökhan; Doğan, Doğanay; Aydın Çivi, Hatice Özlem (2018-12-10)
A novel antenna element for low loss and low-profile dual-plane monopulse arrays is proposed. The travelling wave array has both sum and difference distributions in azimuth. The designed element is the unit cell of an interleaved slotted waveguide array feeding wideband printed antennas via probes inserted into waveguides from the slots. The use of printed antennas enhances the narrow sidelobe and efficiency bandwidth of the closely-spaced slotted waveguide arrays by up to 20%. The unit cells are modelled a...
