The design of microstrip patch antenna (MPA) demands reliable electro-magnetic interactions (EmI) to meet the antenna design requirement. The antenna array faces problem with adjustment of design parameters such as elements dimensions, shape, spacing etc. Under this scenario, mathematical approach required to be essential to design the systematic design of array. But, the realistic models of arrays are computationally expensive in providing accuracy. Thus provide low cost computation, various approaches based on meta-heuristics like particle swarm optimization, genetic algorithms are proven effective against handling of such issues of pattern synthesis i.e., existence of side lobes. But, meta-heuristics requires thousands of function to evaluate the antenna design. In this paper, accurate mathematical modelling approach is presented to design Micro strip Patch Antenna with Optimal Performance. The mathematical model (using MATLAB) includes optimization of side lobes, optimization of radiation as well as reflection responses. The performance analysis of the approach is performed by considering the radiation, reflection coefficients, operating frequency and minimization of side lobes. The simulation outcomes of the antenna design give the reduced computational cost at 10GHz micro strip patch antenna.

“…Compared with the direct connection of different RF front‐ends, the integrating design not only miniaturizes the insertion loss of the circuit but also reduces the interference with each other. On the other hand, to realize compact size, multilayer structure can also be used, which can be realized by low temperature co‐fired ceramic technology, substrate‐integrated waveguide technology, and printed circuit board technology (PCB) …”

A compact wideband balun filtering quasi‐Yagi antenna with high selectivity is proposed. It consists of a quasi‐Yagi antenna integrated with a multilayer balun filter. The quasi‐Yagi antenna is composed of a bow‐tie driver coupled with a director on the top layer, and a ground reflector on the bottom layer. The fourth‐order balun filter has two stepped impedance resonators (SIRs) on the top layer, and two SIRs on the middle layer, which helps improve the frequency selectivity and bandwidth. Moreover, it has two differential ports to feed the quasi‐Yagi antenna. The filtering antenna centered at 2.5 GHz with a wide bandwidth of 22.8% and a pair of transmission zeros is designed and fabricated, which shows a stable radiation pattern with maximum gain of 5.5 dBi and high selectivity.

“…Differential antennas have the advantages of being easily integrated with other differential devices. Therefore, differential antennas are becoming increasingly popular . In the design of filtering antennas, the differential feed is adopted to make up for the deficiency of single feed and realize further miniaturization of RF front end, which is significant for the integration of modern wireless communication.…”

A novel differential filtering antenna with high selectivity is proposed. The antenna is mainly composed of three different‐size patches, a slot, a pair of differential feeding lines, and a line resonator. An air gap is adopted to improve the impedance bandwidth and the filtering performance. The line resonator helps to generate high common‐mode (CM) rejection. Owing to the parasitic concave and convex patches, the filtering performance and the bandwidth of the antenna are enhanced. The parasitic concave patch affects the lower band‐edge selectivity while the parasitic convex patch influences the upper band‐edge selectivity. In addition, the frequencies of two radiation nulls can be controlled independently to achieve two high sharp roll‐off rates by adjusting the lengths of the parasitic patches. Considerable impedance matching bandwidth is achieved through an aperture coupling. Finally, a prototype of the differential filtering antenna is fabricated and tested. The measured results are in good agreement with the simulated results, showing an impedance bandwidth of 9.9% and an average realized gain of 7.5 dBi. Besides, two filter zero transmissions located at 3.40 and 3.84 GHz produced two radiation nulls.
