“…This is because the minimum number of elements required for the original cosine-square distribution coefficients to work appropriately as weighting coefficients for an antenna array is 6 [1]. However, as depicted in Table 2(a), the amplitude distribution coefficients on addition of pedestals works reasonably well for a smaller number of elements (N = 4 in this case) with difference of 1.0592 dB for N = 4 as compared to 0.2335 dB for N = 8 [15]. For still fewer number of elements (N = 2 or 3), the desired distribution is not realized as there is no formation of null in the radiation pattern.…”

Resonance frequency of a Circular Microstrip Antenna (CMSA) depends on its diameter. Hence when CMSA is truncated or sectored into smaller elements, keeping the diameter same, it resonates at almost the same frequency. An analysis of the new antenna arrays designed using these truncated non-identical CMSA elements to realize an amplitude distribution over pedestals leading to a desired first side lobe level (FSLL) has been presented. Truncated elements are designed as non-identical elements based on their gain variation with respect to the standard normalized aperture distribution coefficients. Experimental verification to validate the proposed concept and simulated results has been carried out using an antenna array with eight non-identical elements. There is good agreement between simulated and measured results at 1.76 GHz.

As the demand for high data rates is increasing day by day, fifth-generation (5G) becomes the leading-edge technology in wireless communications. The main objectives of the 5G communication system are to enhance the data rates (up to 20 Gbps) and capacity, ultra-low latency (1 ms), high reliability, great flexibility, and enhance device to device communication. The mentioned objectives lead to the hunting of the millimeter-wave frequency range which lies from 30 to 300 GHz for 5G wireless communications. To design such high capacity, low latency, and flexible systems, antenna design is one of the crucial parts. In this paper, a survey is presented on various antenna designs with their fabrication on different types of substrates such as Rogers RT/duroid 5880, Rogers RO4003C, Taconic TLY-5, etc., at different 5G frequency bands. The different configurations of antennas that covered antenna arrays, multiple-input multiple-output (MIMO) antennas, phased antennas, and beamforming antennas are discussed in detail with their applications. The design of MIMO antennas in the 5G frequency band occupied less space so mutual coupling reduction techniques are required for maintaining the required gain, efficiency, and isolation. This paper is also focused on the mutual coupling reduction techniques and diversity in MIMO antennas.

“…Hence, amplitude tapering of microstrip patch array antenna elements can be achieved by changing their width [8,9]. However, most researchers have concentrated on gain enhancement and reduction of side lobe level, but not on beam shaping [10,11]. Therefore, it is proposed to synthesize amplitude excitations for the shaped radiation pattern generation from a compact patch antenna array by unequal widths of the array elements.…”

This paper presents a novel design structure of a series fed array antenna for desired shaped beam pattern synthesis. The desired beam shape is obtained by varying the width of patch elements. A uniform array is designed for the desired frequency, and then the proportionate values of the widths are calculated using amplitude coefficients obtained from the Woodward Lawson array synthesis method, while keeping excitation phase and inter element spacing constant. The proposed antenna is designed and simulated in HFSS. A prototype is fabricated on FR-4 epoxy dielectric material and tested at 12.5 GHz. The overall antenna has a compact size of 112 mm×34 mm×0.8 mm. The array structure exhibits impedance bandwidth of 1.8 GHz and fractional bandwidth of 15.2%, from 11 GHz to 12.8 GHz frequency range with return loss of −29.6 dB and high gain of 14.7 dB. The series fed configuration results in a VSWR of 1.38 and considerably low side lobe level of −21 dB. There is a fine similarity between simulation and fabrication measurement parameter values such as return loss, VSWR, gain, and bandwidth.
