“…Monopoles and dipoles are usual elements chosen for antenna base element. Dipole element is a good choice because of its stable radiation pattern in frequency domain, good beam shape, enough bandwidth, and ability to become high-gain [16].…”

In this paper, the design and fabrication of a large array antenna with three required, Sum, Difference and Control beams for a monopulse Secondary Surveillance Radar (SSR) is presented. A special array element, which is a high gain dual dipole structure, is designed and tested. This element has 9.6 dB gain in 1060 MHz and does not need any balun. The main challenge of extracting three beams out of one beam feeding networks (BFN) has been resolved efficiently by maximum integration of all three in one network, reducing the number of required modules to one half. The complete 33-element array, working in 1030 MHz and 1090 MHz is designed based on the Taylor array factor. The complex feed network of this 6-meter long array has successfully been synthesized as modular as possible. Sum pattern was designed for 2.7 o azimuth beam width and -20 dB side lobe level and Diff pattern with a deep null in the boresight of the Sum pattern. The Ctrl beam was also designed in order to cover the Sum beam except in the direction of the main lobe.

This research paper presents the design and implementation of low profile printed monopole antenna for Bio medical applications. The proposed antenna is designed for industrial, scientific, and medical frequency band (2.4–2.48 GHz). Four different patch geometries are considered and their performance is analyzed. The various parameter studies on ground length and slot width is performed and the precise dimensions are chosen. The slotted geometry along with stepped ground plane increases the current path and reduces the antenna size. To alleviate the impedance matching, proposed structure is endowed with stub tuning and hence minimum return loss −31 dB is attained. The proposed antenna is built on FR4 substrate and overall dimension (l, w, h) of this antenna is 20 mm × 20 mm × 1.6 mm. Antenna simulations are performed using ADS. The performance parameters of the proposed antenna is examined through simulations and verified with measured data. The measured result shows good concurrence with the simulated results. The proposed antenna exhibits good isolation of −35 dB between co‐ and cross‐polarization. It has stable gain of 2.92 dBi over the frequency range of 2.4–2.48 GHz and achieves 98.6% radiation efficiency.

This paper illustrates the design and performance of microstrip feed elliptical shaped patch antenna having crossed shaped parasitic element. The overall size of antenna is 40 mm × 40 mm × 1.59 mm. For optimization of the performance of antenna, CST Microwave studio 2014 simulator is used while antenna is tested with available facilities under laboratory conditions. Proposed antenna provides triple impedance bandwidth extended between frequency ranges of 2.28‐2.62 GHz, 2.70‐3.96 GHz, and 5.1‐6.29 GHz with flat gain (close to 3‐5 dBi) in the desired frequency range. Good circular polarization conditions are realized at frequency 5.90 GHz for different sets of elevation and azimuth angles with maximum axial ratio bandwidth close to 600 MHz at the same frequency. The SAR values at desired frequencies are much lower than those for specified frequencies of modern communication systems. This antenna may be a useful structure for Wi‐Fi, WLAN, Wi‐MAX communication bands and lower and median UWB bands.
