A compact pattern reconfigurable antenna structure is proposed. The proposed antenna structure is composed of two shorted quarter-wave microstrip patch antennas placed side by side to share a common shorting plane. Therefore, the total length of the antenna is a half wavelength. Pattern reconfiguration is achieved by exciting two antennas with different phases and consequently steering the main beam. With such a compact antenna, beam steering up to 350 is demonstrated.

Design of a multi-layer beam-steering WLAN antenna Yilmaz, Kardelen; Nesimoglu, Tayfun (2018-11-02) This paper represents the design of a microstrip patch antenna which is reconfigurable by means of the effect of a pixel grid overlay that is placed at a certain distance from the antenna. hi addition to beam steering capability, this article will focus on several important parameters of the aforementioned antenna, such as, the directivity, the gain, radiation pattern and polarization. The antenna consists three main parts; a rectangular microstrip patch antenna that has the operating frequency at around 2....
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 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...
An Interleaved LTSA Array on a Waveguide Beamformer with Dual-Plane Monopulse Gultepe, Gokhan; Dogan, Doganay; Aydın Çivi, Hatice Özlem (2019-01-01) A monopulse antenna array is designed by using a novel element combining wideband linearly tapered slot antennas (LTSA) with an interleaved, closely-spaced, travelling wave slotted waveguide array (TWSWA) similar to [1-3]. To decrease the deteriorating coupling between sum and difference rows in previous studies for monopulse operation, adjacent rows of interleaved arrays are designed to have the same amplitude distribution but different propagation constants. So, interleaved arrays generate two simultaneou...
Design and Implementation of Transmitting and Receiving Antenna Pair on Flat Ring Surface Haykir, Yigit; Karadağ, Savaş; Dagdeviren, Birkan; Demir, Şimşek (2018-11-02) In this work, design and implementation of broadside altimeter antenna on circular ring surface are performed. Utilizing array factor formulation, possible locations for circular array elements are chosen. Slitted microstrip patch antennas are used for an efficient design. Satisfactory results are obtained for an altimeter antenna that can be utilized in missile, aircraft or spacecraft applications.
