“…The frequency response in dual band U-slot and pair of rectangular slots cut inside the circular MSA (CMSA), for different slot dimensions, was studied over wide frequency range. It was observed that neither U-slot nor rectangular slots introduce any additional mode, but they reduce the higher order TM 21 mode resonance frequency of the circular patch and thus, along with fundamental TM 11 mode, realizes dual band response [18]. The resonant length formulation for slot mode frequency (modified TM 21 mode) has been proposed [18].…”

The broadband microstrip antenna is realized by cutting the slot inside the patch. The slot introduces a resonant mode near the fundamental resonance frequency of the antenna and realizes broadband response. The compact variations of circular microstrip antenna are realized by placing the shorting posts along the zero field line at the fundamental mode. These shorted antennas have narrower bandwidth. In this paper, a compact half U-slot cut shorted sectoral microstrip antenna is proposed. The detailed analysis has been carried out to study the effect of the slot on various modes of the sectoral patch. It has been observed that the half U-slot does not introduce any additional mode, but reduces the resonance frequency of the higher order mode of the shorted sectoral patch and along with its fundamental mode realizes broader bandwidth. The bandwidth of more than 700 MHz, at the center frequency of approximately 2700 MHz, has been realized.

“…The most serious limitations of microstrip antenna are its narrow bandwidth and poor gain (Balanis, 2005). Various techniques such as shorting post loading (Deshmukh et al, 2013;Kumar and Singh, 2011;Singh et al, 2010), gap-coupling (Kumar, 2014;Kumar and Singh, 2009;Mishra et al, 2019;Sharma, 2014), metamaterials (Yem and Lan, 2018), photonic band gap crystals (Sudha and Vedavathy, 2001), frequency selective surface (Yahya et al, 2018), defected ground structure (Ajay et al, 2019;Kumar and Masa-Campos, 2015;Kapoor et al, 2020;Njokweni and Kumar, 2020), etc., can be used to improve the antenna performance. Multiband antennas are required to be used for different bands applications.…”

In this paper, the design and development of dual-band and triple-band fractal microstrip patch antennas with enhanced gain are presented. The structure is based on the Sierpinski carpet fractal, where the multiband functionality is achieved by applying the fractal iteration technique. The fractal antenna characteristics along with analysis of the reflection coefficient and the radiation patterns for each iteration are presented. The dual-band fractal microstrip patch antenna (DBFMPA) is operating at 4.9 and 5.3 GHz and the triple-band fractal microstrip patch antenna (TBFMPA) is operating at 2.4, 5.3, and 5.9 GHz. The defected ground structure (DGS) and a reflector plane is utilized for enhancing the gain of the antenna. Design and optimization of the DBFMPA and TBFMPA are done using the Computer Simulation Technology (CST) Microwave Studio Suite. The presented DBFMPA and TBFMPA are suitable for industrial, scientific, and medical (ISM) wireless applications.
