“…In this way, in a reduce space; it is possible to achieve an antenna of greater bandwidth and multiband. Combination of internal and external cracks have also been used in some works [6], [12]- [13]. These combinations allow greater versatility in the design of new antennas.…”

This work proposes the study of patch antennas with fractal slots. Initially, a 2.4 GHz microstrip antenna is designed. Then, the slots in the Koch fractals format are inserted with the iteration 0, 1 and 2. Similarly, it is expected that the antenna can be subjected to various functions in other applications. Simulations using CST STUDIO SUITE Student Edition software are shown, in addition to antenna measurements using the Network Analyzer.

“…Axial ratio and impedance matching can be optimized by altering the sizes of slits/slots [6]. Embedded V-slit, slot, and stub on circular patch antennas [7] introduce CP with an AR bandwidth of 2.3% in the UMTS frequency band. Compact-size circularly polarized diagonally symmetric slotted microstrip patch (DSSMP) antennas with different shapes of slots with fixed volume are proposed.…”

Modern communication systems employ wideband antennas with circular polarization (CP) radiation. In this work, asymmetric modified bow‐tie (ABT) and symmetric modified bow‐tie (SBT) slotted circularly polarized single‐point probe‐fed circular patch antennas with dimensions of 40 mm × 40 mm for wideband applications are proposed. A 10 dB RL bandwidth of 350 MHz with CP, 3 dB axial ratio (AR) bandwidth of 100 MHz, peak gain of 4.9 dBic, and 10 dB RL bandwidth of 530 MHz with CP, 3 dB AR bandwidth of 140 MHz, peak gain of 5 dBic are obtained for ABT and SBT slotted circular patch antennas, respectively. The proposed SBT slotted patch is scaled up and down to 50 mm × 50 mm and 30 mm × 30 mm, respectively. The proposed scaled‐up version offers 10 dB RL and 3 dB AR bandwidths of 340 MHz and 80 MHz, with a peak gain of 5 dBic. The scaled‐down version offers 10 dB RL and 3 dB AR bandwidths of 710 MHz and 180 MHz, with a peak gain of 5.25 dBic. These prototypes are suitable to work in IEEE 802.11a WLAN, ISM, and IEEE 802.11ac applications. The measured and simulated results are then discussed and compared.

“…S. Mathew et. al., [21] has proposed a compact circular microstrip patch antenna with V shaped slit and 48% size reduction has been reported. Some investigations on size reduction by cutting different slots on patch have been carried out in [22][23][24][25][26][27].…”
