The antenna has a rectangular patch, 50 Ω microstrip feed line and partial ground plane with three round grooves to enhance the bandwidth. The characteristics of the designed structure are investigated using high frequency structure simulator (HFSS) and computer simulation technology softwares (CST). The achieved percentage bandwidth of the proposed design with return loss RL ≥ 10 dB is over 175%. Promising peak gain with good impedance matching and omni-directional radiation pattern are obtained.

The band notch are designed to reject the Worldwide Interoperability for Microwave Access (WiMAX) applications based on the IEEE 802.16 standards for the frequency band 3.3–3.8 GHz and the Wireless Local Area Network (WLAN) applications band that based on the IEEE 802.11 standard for the frequency band of 5.15–5.825 GHz. The antenna consists of a circular patch, co-planner waveguide (CPW) feed line with 50 Ω input impedance, T-strip connected to the top of the patch and complementary circular slot type split ring resonator (SRR) is etched at the bottom edge of the patch. The antenna covers the UWB frequency band (3.1–10.6) GHz beside extra band for Bluetooth frequency range (2.4–2.48) GHz. The characteristics of the designed structure are investigated using finite element method based electromagnetic solver, HFSS. Promising return loss data with good matching, good gain, high efficiency and omni-directional radiation pattern are obtained.

The antenna consists of a rectangular patch etched on FR4substrate with 50 O feed line. The rectangular patch has one round cut at each corner with one slot in the ground plane. The simulated bandwidth with return loss (RL) P 10 dB is 3.42-11.7 GHz. The rejected bands are the WLAN and X-bands, achieved by inserting slots in the patch and the feed. The simulated results of the proposed antenna indicate higher gain at the passbands while a sharp drop at the rejected bands is seen. The radiation pattern is of dipole shape in the E-plane and almost omnidirectional in the H-plane. The high frequency structure simulator (HFSS) is used to design and simulate the antennas behavior over the different frequency ranges. Measurements confirm the antenna characteristic as predicted in the simulation with a slight shift in frequencies.

The antenna consists of a rectangular patch, 50 Ω microstrip feed line and partial ground plane. Modifications are introduced in the antenna to enhance the bandwidth; adding one cut in the patch upper and lower corners, adding two steps to the microstrip feed line and adding one rectangular grove to the partial ground plane. The simulated results using high frequency structure simulator (HFSS) and computer simulation technology software (CST) show high bandwidth at RL ≥ 10 dB (3.5–14.9) GHz with percentage bandwidth of 123.91%. Promising peak gain, dipole-like radiation pattern in E-plane and good omni-directional radiation patterns in H-plane are achieved.

The antenna is designed on FR4-substrate and fed by 50 Ω microstrip feed line with two quarter wavelength transformers for better impedance matching. The bowtie right side has a horizontal slit to enhance the bandwidth and it is connected to the microstrip feed line, while its left side is connected to the partial ground plane in the back side through shorting pin. The proposed antenna is investigated using the high-frequency structure simulator (HFSS). The simulated scattering parameter S11 (Reflection Coefficient) result shows bandwidth ranges from 3.05 to 10.8 GHz at return loss (RL = |S11|) ≥ 10 dB. The proposed antenna has high gain value, omnidirectional radiation pattern in the H-plane and mushroom-Shaped in the E-plane at lower frequency edge are achieved.

The hexagonal patch is designed on FR4-substrate, having circular cuts at its vertices and fed by 50Omega50 \Omega 50Omega micro-strip triangular tapered feed line. This antenna with a partial ground plane and five half circular sleeves achieves a 26.15 GHz bandwidth (with return loss geq10\geq 10geq10 dB). Triple-frequency band rejections are achieved by adding an inverted E-shaped stub in addition to two triangular slots in the patch and square slot with a parasitic square inside. The proposed antenna is investigated using the high-frequency structure simulator (HFSS). The simulated scattering parameter S11 (Reflection Coefficient) results show three band rejections (1.66. – 3.29), (4.72 - 5.81) and (7.86 - 8.62) GHz to reject the unwanted interference from several applications as WiMAX and satellite communications. A small value of gain at the rejection bands with good radiation patterns in E-plane and H-p...

The ground slot is designed at 5.7GHz to have a wide rejection band 4.2-7.0 GHz. The antenna has a circular patch with co-planner waveguide (CPW) feed with 50 Ω input impedance. The characteristics of the designed structure are investigated using finite element method based electromagnetic solver, HFSS v.11.

The enhanced ultra wide band (UWB) antenna consists of a rectangular patch fed by a 50 Ω microstrip feed line and partial ground plane. The bandwidth enhancement is achieved by making three modifications on the partial ground plane; adding two rectangular sleeves, adding one rectangular groove and adding two rectangular slots. The characteristics of this antenna are investigated using high frequency structure simulator (HFSS). The proposed design achieves large bandwidth at return loss RL ≥ 10 dB of (3.4-22.4) GHz (147.29%). Promising peak gain with good impedance matching and omni-directional radiation pattern are obtained.
