A fully printable and conformal antenna array on a flexible substrate with a new LeftHanded Transmission Line (LHTL) phase shifter based on a tunable Barium Strontium Titanate (BST)/polymer composite is proposed and computationally studied for radiation pattern correction and beam steering applications. First, the subject 1× 4 rectangular patch antenna array is configured as a curved conformal ...

Recently, there has been great interest in the development of advanced radar systems with phased arrays [1], [2]. In traditional multichannel radar array systems, the number of receivers should be equal to the number of receiving antennas, so the hardware expense and power consumption are very high [3]. A radar array system based on antenna switching is a promising substitute due to its lower c...

This paper proposes the 2-D DOA estimation method with an arbitrary planar antenna array using MS technique in combination with EM Algorithm, and shows good performance of the proposed method in estimation accuracy and computation time.

A 60 GHz-band four-element integrated planar phased array is proposed. Each antenna element is integrated with evenharmonic I/Q mixer compromised of anti-parallel diode pairs (APDPs) for the adaptive beamforming systems.

In the context of passive sources localization using antenna array, the estimation accuracy of elevation, and azimuth are related not only to the kind of estimator which is used, but also to the geometry of the considered antenna array. Although there are several available results on the linear array, and also for planar arrays, other geometries existing in the literature, such as 3D arrays, ha...

A study on the MIMO channel capacity of a modified dual-element planar inverted-F antenna (PIFA) array is presented. The dual-element PIFA array consists of two modified PIFAs which are mounted on a small mobile terminal operating at 2.5 GHz. The relationship between mutual coupling and channel capacity is analysed by comparing the modified dual-element PIFA array with a conventional dual-eleme...

A single element modified tree profile shape (MPTPS) antenna is implemented to investigate suitability in future communication different sub-6 GHz spectrum band. The size of MPTPS 40 × 25 mm2. electronic band gap (EBG) and partial ground plane (PGP) techniques have utilized tune this antenna. works from 2.81 – 7.23 ...

The cylindrical geometry can offer certain desirable antenna characteristics that are not provided by planar elements. In this paper, a three-element cylindrical conformal array antenna has been presented as a candidate for use in wireless communications and Radio Frequency Identification (RFID). Each element in the array is a microstrip fed rectangular patch antenna designed to resonate at 2.4...

Broadcasting, radar, sonar and space telecommunication systems use phased arrays to produce directed signals be transmitted at the desired angle. This system requires a large number of antenna elements. The presence faulty element(s) in an array causes asymmetry, which results deformed radiation pattern with higher sidelobe levels. Higher levels indicate waste energy by transmitting receiving u...
