The lower band and mid band ‘5G’ are known to use the frequencies in the range of 600 MHz – 6 GHz worldwide, especially 3.5GHz to 4.2GHz. A new modified multi slot compact planar ultra-wideband Microstrip patch antenna with a split ground plane has been proposed in this paper. The size of the antenna occupies volume of 34x30x1.7 (1734 mm^3) which has been designed on a FR4 epoxy substrate with dielectric constant of 4.4. In order to provide dual wideband characteristics, a ‘T and G ’shaped slots with split ground plane using line feeding structure has been used. The effects on the return losses v/s frequency for the antenna using different substrates with varying dielectric constants for the same dimensions has been studied in this paper. The proposed antenna operates in dual band with first band being a narrow band ranging from 1.92GHz to 2.06GHz and the second band is an ultra-wide band which ranges from 3.40 GHz to 9.6 GHz. The split ground plane and slot size variations in the T and G slot geometry helps in retrieving the dual bands. The proposed antenna is covering applications from LTE band No 40, UMTS IMT-2000, Wimax (3.5/5.55GHz), ISM WLAN 5.2/5.8GHz and RFID etc. The direct line feeding method which uses a 50Ω line with width of W=3mm has been used for the micro-strip line. With split ground plane, coupling between the slots plays role for achieving the good bandwidth. The analysis of return loss (dB), bandwidth, VSWR (Voltage Standing Wave Ratio) of patch antenna with different substrates and variation of the sizes of slots in shapes has been performed using HFSS tool [12] and results has been studied in this paper.

In this research paper a design of Microstip patch antenna for the ultra-wide band (UWB) applications is presented. Ultra wide band antennas has very wide band of operation which accommodates many communication frequencies as set by the federal commission of communication. The UWB antennas is based on the micro strip patch antenna concept and the design of the antenna is based on the stack antenna or multi-layer antenna. Stacking is used in designing for increasing the bandwidth of the antenna so stacking concept is good for the designing of the UWB antenna. The feeding used to feed the antenna is micro strip line feed. Micro strip line feeding technique is one of very popular feeding technique to feed the antenna because its fabrication is very simple. The proposed design is simulated in the CADFEKO software which is very useful for the design and analysis of a wide range of electromagnetic problem. It has many applications to simulate 3D electromagnetic circuit included antenna design, micro strip antenna and circuits. The simulation results shows the antenna bandwidth of 13.9 GHz from 2.6 to 16.5 GHz. So we can clearly say that the antenna is ultra-wide band in nature.

AbstractA dual band-notched MIMO/Diversity antenna is proposed in this paper. The proposed antenna ensures notches in WiMAX band (3.3–3.6 GHz) besides WLAN band (5–6 GHz). Mushroom Electromagnetic Band Gap (EBG) arrangements are employed for discarding interfering frequencies. The procedure followed to attain notches is antenna shape independent with established formulas. The electromagnetic coupling among two narrowly set apart Ultra-Wide Band (UWB) monopoles is reduced by means of decoupling bands and slotted ground plane. Monopoles are 90° angularly parted with steps on the radiator. This aids to diminish mutual coupling and also adds in the direction of impedance matching by long current route. S

This paper explore about   the micro strip patch antenna design with a defected ground structure (DGS) for dual band operation. The intend of this paper is to design an micro strip antenna, under the frequency at 2.4 GHz and 5.2 GHz that can be utilized for BLUETOOTH and WLAN applications. The feeding technique used here is coaxial feed technique. The above said double band property can be established by etching U-slot in the ground plane. Being periodic structure slot is selected and it is imposed on ground plane. The periodic structures naturally modify the method of propagation of the electromagnetic signal passing on to the antenna. Essentially its core is to vary the parasitic capacitance and inductance of the material through which the substrate is made. This may moreover leads to the reduction in size and progress the performance of the antenna. Micro strip patch antennae are favored due to the fact that these are small in size, inexpensive, consume low power and easy to fabricate and also be designed to meet wide band application requirements.

Abstract In this paper, using in-depth simulations and measurements, a simple and compact design is engineered for making a circular ring microstrip patch antenna radiating element which is suitable for different ultra wide band(UWB) applications. This design approach is different because it has not utilized the usual method of using a set of electromagnetic equations and calculations to make the radiating antenna. Measurements and simulations were performed on Microwave CST. Using this measurement engineering approach, novelty of proposed antenna structure is obtained by making the required changes in the ground plane. The measurements showed that truncating the ground plane by a square shape structure of 2.5mm by 2.5mm size at the feed point was practically significant to provide an impedance bandwidth (\({S}_{11}cript>\)) ranging from 2.75 GHz to 32.035 GHz with a VSWR which is less than 2. For this entire bandwidth the directivity has shown a variation from 0.8 dBi to 7.9 dBi. The compact size (33mm x28mm x1.57mm), low design complexity, very high bandwidth, good directivity and satisfying VSWR has made this antenna unique among all previously presented UWB antennas.
