“…Various techniques in previous works have been developed to improve the impedance bandwidth of microstrip antennas [9]- [19]. For this purpose, utilizing the impedance matching networks [9], [10] and inserting the slots into the patch are taken into consideration as two common methods [11]- [13]. Various shapes of slots on the patch such as U-shaped-slot patches [14], [15], E-shaped patches [16], [17] and V-shaped patch [18], [41] provide a wide bandwidth up to 33%.…”

This study presents two new designs of reduced size broadband microstrip patch antennas for ultra-wideband (UWB) operation. A folded triangular patch’s feeding technique, V-shaped slot, half V-shaped slot and shorting pins are employed to design the suggested antennas. The shorting pins are applied at the edge of structures to miniaturize the size of the patches. The suggested design with the V-shaped slot provides the measured impedance bandwidth (S11˂-10 dB) of 3.91-12 GHz (101.7%) for broadband application. In the suggested design with the V-shaped slot, the wide bandwidth with an acceptable size reduction is achieved. By introducing a suggested half design with the half V-shaped slot, the impedance bandwidth of the proposed half structure is improved from 4 to 17.22 GHz. The half design includes a measured impedance bandwidth of 124.6% with reduced size of more than 93% compared to the corresponding full design and an enhanced measured bandwidth of 23%. The obtained radiation and impedance results show that the suggested designs are applicable for wideband operation. Besides, the effects of some basic concepts and surface currents on the suggested structures are investigated to explain their broadband performance.

“…10 The patch antenna is one of the common antenna forms for digital array radar for its low profile and excellent performance, and various methods are implemented to achieve different functions. [11][12][13][14] However, there are few literatures about patch antenna integrated with RF internal calibration line. The electric field of patch antenna is mainly concentrated between the ground layer and the radiation patch layer.…”

This article presents a novel structure of integrated radio frequency(RF) internal calibration line for patch antenna without increasing the antenna profile. The RF internal calibration line is realized by introducing a microstrip line in the middle of the nonradiation side of the two patch antenna units. Metalized grounding strips (MGS) are composed of metal strips on the upper surface of printed circuit board, metalized ground vias, and the ground layer. The MGS with gaps is set between the calibration line and the antenna units to adjust the mutual coupling. A 16 Â 32 antenna array is fabricated and measured for verification. The measured results are in good agreement with the theoretical simulation. It shows that the mutual coupling between the coupling port of the calibration line and each port of the antenna unit is between À32.5 and À27 dB in the X and Ku frequency band (12-13.2 GHz, 9.5% relative bandwidth), and the antenna pattern is not distorted by the integrated calibration lines.

Novel gap-coupled variations of rectangular and circular microstrip antennas backed by rectangular slot cut ground plane are proposed. The slot on the ground plane below each of the patch, reduces the resonance frequency of the fundamental mode, thereby giving wideband response at the reduced frequency. With reference to the gap-coupled design at reduced frequency using the conventional ground plane, a slot cut ground plane design yields a reduction in the total patch area with higher BW and comparable gain values. On thinner Taconic substrate (h < 0.02λ g ), using rectangular and circular patches, the optimum result is obtained with parasitic patches gap-coupled along the two diagonal axis. In the rectangular patch design, bandwidth of 148 MHz (6.04%), peak gain of 9 dBi, for patch size reduction of 33.33% is achieved, whereas using the circular patches, these values are, 138 MHz (5.48%), 9.2 dBi and 38.4%, respectively. In all the proposed gap-coupled designs, for the maximum possible frequency reduction, BW and gain realized is higher as compared with the gap-coupled design with a normal ground plane.
