“…Microstrip line feeding is employed in that paper. The antenna is designed for different substrates and for varying thickness of the substrate [1]. A resonator with inductive nature is used as reflector and a parasitic element is used as an intermediate element in the antenna in order to augment the bandwidth and isolation to the required level nearly of about 45dB of isolation and maximum gain is 4.9 dB.…”

With the amelioration and flexibility of communication devices, there is an urge for devices aiding more than one frequency band with enhancement in bandwidth, gain and directivity. This paper proposes a lozenge shaped monopole antenna which envelopes Ku-band and K-band. The proposed antenna possesses a modest structure with modified lozenge shaped radiating patch with triangular and pentagonal shaped slots. In case of simulation the achieved bandwidth for Ku-band frequency range is 0.76 GHz and for K-band frequency range is 6.93 GHz whereas in case of measured results the bandwidth achieved is 0.4 GHz and 0.52 GHz for Ku band and 3.42 GHz in case of K band. The maximum achieved peak directivity is 8.739 dB. The maximal values of achieved peak gain and peak realized gain are 5.757 dB and 5.523 dB respectively. The design is implemented in ANSYS HFSS software.

A semi-circular patch antenna (SCPA) is designed for WiMAX and WiFi-5/6 communications. The footprint of the proposed SCPA is only 30 Â 40 Â 1.575 mm 3 , which is composed of a semi-circular patch and a partial ground plane. The main strength of this work is that the estimated wide dual-frequency span of 2.39-3.75 GHz and 5.39-7.18 GHz are contributed with two sharp resonances at 2.77 and 6.46 GHz, respectively. The proposed SCPA has been practically tested after fabrication. The measured results confirm that the designed antenna achieved the bandwidth necessity for WiMAX 1.5(2.5-2.69 GHz), WiMAX 2 (3.4-3.6 GHz), and . In the two resonance frequencies of 2.77 and 6.46 GHz, the designed antenna achieved a gain of 2.558 and 4.109 dB, respectively. In addition, the SCPA also manifests good radiation properties and achieves an average efficiency of more than 90%. A professional version of the 3D electromagnetic simulator is utilized to examine the effect of diffident parameters and model the tested antenna.semi-circular patch antenna, partial ground plane, WiMAX, WiFi-5/6, CST | INTRODUCTIONWireless technologies are becoming progressive due to the dramatic increase in the demand for cellular internet connectivity to billions of wireless device users worldwide. 1 Different modern broadband wireless technologies like Bluetooth (2.4-2.485 GHz), LAN (5.47-5.725 GHz), WiMAX (3.4-3.6 GHz), mobile communication, radar, satellite communication and so forth use different frequency bands of the spectrum to meet the increasing demand of highspeed data transmission.

Recently, WiFi-6 (802.11ax) has been introduced, providing a peak data transfer speed of up to 9.6 Gb/s. 5 All wireless systems need a low-cost, simple and compact antenna to communicate effectively. 6 Due to low profile, lightweight and compactness features with higher efficiency, microstrip patch antennas have become very popular in current wireless devices. 7 A good number of antennas have already been reported to operate at the 5.925-7.125 GHz band. For example, for WiFi applications, Jianzhong and the rest 8 propose a dual-band miniature slot antenna. In the bottom layer of the designed antenna, there is a slotted radiator fed by an L-shaped microstrip line and resonating at 2.45 and 5.8 GHz. With an overall size of 20 Â 21 Â 1 mm 3 , the antenna achieved dual working bands of 2.42-2.49 GHz and
