“…MPAs comprise narrow BW that is approximately 1-5%, which is the most major limiting factor for its widespread applications. Most of the previous contributions in this research area were to increase the BW of MPAs [1,2], and therefore, several measures have been introduced to achieve this objective, including modified shape patches, which is a method of modifying the shape of patch [3][4][5][6][7][8], utilization of slotted ground structure [9][10][11][12][13], modification of rectangular and circular patches to rectangular [14] and circular rings [15,16]. Another method includes an impedance matching network method proposed to enhance the MPAs BW [17][18][19].…”

Abstract-In this paper, a new method that called the "Stepped Cut at Four Corners" is introduced to design a multi-mode/broadband modified rectangular microstrip patch antennas (MRMPAs). In order to become acquainted with the new method, the design process of a monopole broadband MRMPA suitable for multifunctional wireless communication bands is explained. The methodology of the proposed broadband MRMPA design is presented in six stages. The first stage is designing a single-mode RMPA. Subsequently, by creating a step at the corners using the proposed method a dual-mode antenna is obtained at the second stage, while the triple-mode and multi-mode antennas are designed, at the third and fourth stages respectively. Two types of broadband antennas are obtained, the stepped line and straight line antennas. By increasing the number of steps, the antenna's operating bandwidth (BW), with return loss less than −10 dB, covers the frequency range from 900 MHz to 2.6 GHZ, which is suitable for GSM (900 MHz and 1.5 GHz), WiFi (2.4 GHz) and LTE (2.6 GHz) applications. In addition, the antenna prototype has been fabricated and measured in the all stages, in order to validate the simulation results, and there is a close agreement between the simulated and measured results.

“…Accordingly, the multiband antenna is desired in many systems. In the literature reviews, there are various multiband antennas that have been developed over the years, which can be utilized to achieve the objectives of multiband operation, for instance, the PIFA [1,2] for using in mobile phone application, the slot spiral antenna [3] for dual band or multiband operation, the triangle-shaped monopole antenna [4], and other [5][6][7][8][9][10][11][12][13][14][15][16][17][18][19][20][21][22][23]. Recently, the developing multiband antennas have been improved due to use of the fractal concept.…”

Abstract-This paper presents a multiband slot antenna with modifying fractal geometry fed by coplanar waveguide (CPW) transmission line.The presented antenna has been designed by modifying an inner fractal patch of the antenna to operate at multiple resonant frequencies, which effectively supports the digital communication system (DCS 1.71-1.88 GHz), worldwide interoperability for microwave access (WiMAX 3.30-3.80 GHz), IMT advanced system or forth generation mobile communication system (3.40-4.2 GHz), and wireless local area network (WLAN 5.15-5.35 GHz). Manifestly, it has been found that the radiation patterns of the presented antenna are still similarly to the bidirectional radiation pattern at all operating frequencies. The properties of the antennas, for instance, return losses, radiation patterns and gain are determined via numerical simulation and measurement.Corresponding author: C.

“…This antenna may be a useful alternative to the heavy waveguide structures as EMI sensors. Though the major limitation with such an approach is the narrow band performance of this antenna, this study may be extended for other microstrip antennas with broadband characteristics [16][17][18][19].…”

Abstract-This paper presents the result for antenna factor of microstrip patch antenna when used as electromagnetic interference (EMI) sensor. Antenna factor is an important parameter of a sensor used for EMI measurements. The microstrip antenna has found wide application as transmit and receive antenna in modern microwave systems. In this paper, a new application of microstrip antenna as EMI sensor is presented. The result for antenna factor versus frequency of a microstrip patch antenna is presented using commercial software CST Microwave Studio. Also the experimental results for a prototype antenna are presented and compared with the simulated result.
