Design and realization of microstrip linear antenna array based on siw (substrate integrated waveguide) feed network /

Özgün, Ali
A microstrip patch antenna array with substrate integrated waveguide (SIW) feed network is designed and realized. With this configuration, waveguide which is advantageous in high frequency designs is integrated to antenna array in planar form by eliminating the drawback of the bulky structure of them. The design is based on an E-plane SIW power divider in multilayer form. For the feed network, a 4-way E-plane SIW power divider is constituted with 3-layered structure and an antenna system is obtained by merging the antenna layer with this 3-layered feed network. Through this multilayer feed network, resultant antenna system has a compact structure which is not enlarged by the feeding part. The developed network has comparable performance with microstrip counterparts and it is more advantageous for higher frequencies due to the planar waveguide structure. Through the realization of the design, TRL calibration technique is applied to extract the effects of the non-SIW parts from the measurement results.


Design of asymmetric coplanar strip folded dipole antennas /
Karaciğer, Kamil; Alatan, Lale; Department of Electrical and Electronics Engineering (2014)
This thesis includes the design, simulation, production and measurement of an asymmetric coplanar strip folded dipole antenna suitable to be used as an element in a linear array operating at S-band (2.7 GHz - 3.3 GHz). In this same manner, its usefulness as an array antenna is also explored in this thesis. This antenna element consists of a microstrip line feed, microstrip to coplanar stripline transition (BALUN) and asymmetric coplanar strip (ACPS) folded dipole. The planar folded dipole can be constructed...
Design and realization a quasi yagi antenna array and its feed system printed on a ceramic substrate for x-band radar applications
Atabay, Berkay; Dural Ünver, Mevlüde Gülbin; Department of Electrical and Electronics Engineering (2019)
This thesis includes design, simulation, realization and measurement of a four-element quasi- Yagi antenna array printed on a ceramic substrate for X-band radar applications. The microstrip array antenna is designed using four quasi-Yagi antennas in a linear configuration and is printed on Alumina 99.6% substrate made by Coorstek Corporation. The antenna can fit into small areas because of compact structure due to the use of high dielectric constant substrates. In addition, the use of alumina ceramic substr...
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...
Design of an active microstrip array using a microwave circuit simulator
Demir, S; Toker, Canan; Hizal, A (1997-02-26)
An active antenna array design and simulation of this design with a microwave circuit simulator are presented. This active antenna array is a TV receive only (TVRO) antenna operating at 10 GHz. It is a 8x4 array of rectangular microstrip patch antennas. Eight low noise pHEMTs are placed in the antenna. Passive antenna characteristics are usually obtained by analytical techniques or using special softwares for this purpose. The numerical representation as well as the nonreciprocal nature of the active device...
Design of a Re-configurable dual frequency microstrip antenna with integrated RF MEMS switches
Onat, Sinon; Ünlü, Mehmet; Alatan, Lale; Demir, Şimşek; Akın, Tayfun (2005-07-08)
The complete design of a re-configurable dual frequency antenna structure, including its integrated RF MEMS switches and their actuation lines together with a CPW feed, is introduced. The number of switches used in the inset is decreased compared to the hybrid design we presented previously (Onat, S. et al., IEEE Int. Antennas and Propag. Symp., vol.2, p.1812-15, 2004). Instead of utilizing available RF MEMS switches, new switches suitable for this application are designed. Two different switch configuratio...
