“…Broadband or ultrawideband antennas not only provide a satisfactory communication link but also the chances of jamming the signal are minimized. Several micro-strip antennas operating in Ku band have been reported, 10,[18][19][20][21][22][23][24][25][26][27][28][29][30] and we present a comparative table of those antennas operating specifically in the frequency band of 12-20 GHz.…”

“…A partial rectangular ground plane is used for enhancing the impedance bandwidth of proposed antenna as shown in Figure 3(c). The type of substrate used is FR4 (20×18×1.5) mm 3 , the gap between the top layer of circular-shaped MSA and ground plane layer is equal to 1.65mm. In addition, microstrip line feed is the type of feeding used to excite this antenna; it is the simplest type of feeding method.…”

“…This increases attention comes from the development in handheld wireless devices such as mobile phone, computers and navigation system [2]. MSA has many fascinating features such as size compactness, cheap, low profile, lightweight and easy fabrication process [3]. On the other hand, it has a drawback of narrow bandwidth [4].…”

“…A partial ground plane with hexagonally shaped slot is used to improve impedance bandwidth of the antenna. FR4 substrate is used (39×25×1.59) mm 3 with permittivity of 4.4. Simulation results indicate that this antenna has a broad operating bandwidth with three resonant frequencies at 2.4GHz, 3.2GHz and 5.6GHz, and omnidirectional radiation pattern.…”

In this paper; a wideband fractal circular rings shaped microstrip antenna over partial rectangular ground plane is presented. Fractal geometry technique is used in order to take advantage of its selfsimilar property which lead to attain not only size miniaturization but also wider bandwidth and iteration method is utilized that reach up to third iteration. The proposed model is simulated by High Frequency Structural Simulator (HFSS) package. Such model is designed on FR4 substrate with a compact size of (20×18×1.5) mm 3 , 4.3 permittivity and 0.02 loss tangent. The microstrip line feed is used to feed this antenna with a length of 4.65mm and width of 3mm, in order to increase the impedance bandwidth of proposed model to 67.64%. This model is designed to operate at a range of frequency (4.5-9.1) GHz with two resonant frequencies at 5.6GHz and 8GHz. The length of ground plane Lg is optimized for enhance antenna parameters such as input reflection coefficient and Bandwidth. The simulation results show that the input reflection coefficient values are-54.5 dB and-46.5 dB at two resonant frequencies 5.6GHz and 8GHz. Also, radiation efficiency of proposed antenna is 97.29% with peak gain of 4.34dB. This antenna is appropriate for various wireless Applications such as satellite communication, weather radar, (Industrial Scientific Medical) ISM band and (Wireless Fidelity) Wi-Fi.

The purpose of this work is to miniaturize a rectangular patch antenna which resonates at 2.4 GHz. To achieve this, we present a new geometry of a pi-shaped slot with three annular rings as a Defected Ground Structure (DGS). DGS is a periodic etched structure or aperiodic sequence of configurations, and it has been used to switch the resonance frequency from starting value 13 GHz to an ending value at 2.4 GHz without any changes in the areas of the actual rectangular microstrip patch antenna (RMPA). The proposed antenna is structured on an FR-4 substrate with thickness 1.6 mm and permittivity 4.4. The general size of the ground plane is 34 × 34 mm 2 . Using the optimal position and dimension of the pi-shaped slot on the ground, the resonant frequency is reduced to 2.4 GHz, which signifies an 81.53% decrease. Proposed antennas with and without DGS are simulated by using High-Frequency Structure Simulator (HFSS) and Advanced Digital System (ADS) Agilent technology, fabricated, and measured for Wireless Local Area Network (WLAN) application.
