An Inverted L-Shape Fed Microstrip Patch Antenna for Mobile Communication

Secmen, Mustafa
Hizal, Altunkan
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 spans 1900-2700 MHz covering Bluetooth, Wireless Local Area Networks (WLAN) and Universal Mobile Telecommunications System (UMTS) bands. Simulation and measurement results show that the antenna has wide beamwidth, low return loss and cross polarization; but, comparably higher back lobe level making the antenna more suitable for indoor applications. However, the antenna can be modified to be used in outdoor applications by increasing the ground plane size, which results in lower back lobe levels.

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 1...

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 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 ...
Beam Steerable Traveling Wave Meander Line Antenna Using Varactor Diode for X-Band Applications
Gokalp, Nihan; Aydın Çivi, Hatice Özlem (2008-07-11)
This paper presents a novel beam steerable meander line antenna with varactor diode for X-band applications. Beam steering has been achieved by loading the arms of the meander line antenna with varactor diodes. The capacitances of the varactor diodes have been controlled by DC bias voltage. Instead of varactor diodes, RF-MEMS variable capacitances can be used to scan the beam. Since the insertion loss of MEMS capacitances are small compared to loss of varactor diodes, use of MEMS capacitors will increase th...
Design of dual-frequency probe-fed microstrip antennas with genetic optimization algorithm
Ozgun, O; Mutlu, S; Aksun, MI; Alatan, Lale (2003-08-01)
Dual-frequency operation of antennas has become a necessity for many applications in recent wireless communication systems, such as GPS, GSM services operating at two different frequency bands, and services of PCS and IMT-2000 applications. Although there are various techniques to achieve dual-band operation from various types of microstrip antennas, there is no efficient design tool that has been incorporated with a suitable optimization algorithm. In this paper, the cavity-model based simulation tool alon...
