Millimete wave is a fequency anges between 30GHz to 300GHz in an electomagnetic spectum. The poposed antenna consists of T- shape adiating patch mounted on ectangula substate (FR4-4) and micostip line fo antenna feeding. An evolutionay algoithm called paticle swam optimization was used to optimize the length and width of the poposed antenna patch. The poposed antenna gives tiple bands with cental fequencies at 4GHz, 51.5GHz and 60GHz. The antenna offes minimum etun loss of -19db, -4db and -19.5db at 4GHz, 51.5GHz and 60GHz espectively. The etun loss impedance bandwidth of 5GHz fo the fist band, 8.4GHz fo the second band and 5GHz fo the thid band was obtained. The poposed antenna was analyzed using Ansoft High Fequency Stuctue Simulato (HFSS) and MATLAB 013. Radiation chaacteistics of this patch antenna ae obseved at vaious esonating fequencies.

Micostip patch antenna povides multiple bands oppotunities and have a compact stuctue, hence it emeged as a pomising candidate fo hand held devices. Micostip patch antenna has vaious advantages such as low cost, light weight, easy to manufactue etc. Despite of vaious advantages, a majo pitfall that micostip patch antennas suffes is naow bandwidth. With the massive upgade of netwoks, the cuent spectum assigned fo wieless communication has theoetically eached its maximum system utilization. Millimete-waves ae anticipated to be pomising candidate fo the upcoming wieless solutions [1]. Unused available spectum at millimete wave fequencies has a potential to compete with the equiements of futue 5G systems whee high capacity and fast speed ae the distinguishing featues to achieve. On the othe hand thee ae seveal citical limitations necessay to be esolved at millimete wave spectum, such as the atmospheic attenuations and absoptions, which becomes moe obvious at high fequencies [1]. It is suggested that antenna should be offeing high bandwidth to suppot a wide ange of system sevices to function simultaneously and high gain to ovecome the atmospheic absoptions at these ange fequencies []. Moeove, the antenna should be low pofile, low cost and light weight that ae convenient to be integated with plana and non-plana sufaces. Recent wok used defected gound stuctue in thei design [1] which is one among seveal techniques applied to enhance the opeating ange of the patch antenna. Defective gound stuctues enhances the pefomance of an antenna by ceating a patial gound in the gound plane [3]. The added slot is esponsible of alteing the excitation pocess of gound plane. Howeve, the stuctue ceates additional effective inductance and capacitance as well; maintain the thin pofile chaacteistics of the plane [1]. The desied fequency can be obtained by changing the length, width and the position of the slot. A lot of eseach has been caied out in the development of multiband, wideband and ultawideband using defective gound stuctues [4-8]. Most of the antennas that used defective gound stuctue ae low fequency band, single band opeation and multiband millimete wave opeation [9]. This poposed antenna did not use defective gound stuctue.

Jabie, et al etun loss bandwidth of the patch antenna can be calculated as F F F H L %BW = * 100 C (1) In (1), F H is High cut off fequency, F L is Low cut off fequency and F C is the Cente fequency.. PSO TECHNIQUES Pso is a computational method that optimizes a poblem by iteatively tying to impove a candidate solution with egad to a given measue of quality. In pso, paticles potentials solutions fly though the poblem space. Each paticle keeps tack of its coodinates in the poblem space which ae associated with the best solution (fitness) it has achieved so fa (the fitness value is also stoed) and is called the pesonal best [10]. Following a simila patten anothe value is tacked, this value is named as the best value obtained so fa by pso and is known as the global best. An N-dimensional coodinate is used to epesent each position, in which each dimension is equivalent to a paamete to be optimized. The velocity (VN) and position (XN) of one paticle is updated as [11] [1]. V N = W V N + C 1and () (PBEST, N-X N) + C and () (GBEST-X N) () Hee W is called the inetia weight and its value chosen between 0 and 1 fo the mathematical convenience, evaluates the extent to which the path of the paticle doesn t deviate due to the influence of PBEST and GBEST. C1 and C ae the factos that goven the deviation due to PBEST and GBEST [1]. The amount of deviation due to PBEST is detemined by C1 and C is a facto detemining how the paticle is affected by the est of the swam. The andom function (and) is used to intoduce the slight andomness o unpedictable natue of swam behavio. Accoding to [13] the position (o location) of each paticle is updated as: X N = X N + T V N (3) Fo a given time step T whose value is chosen to be unity. Pso use to solve powe system [16], featue selection fo stuctue-activity coelations in medical applications [17], biological applications [18], size and shape optimization [19, 0], envionmental applications [1], analysis in chemical pocesses [], bioinfomatics [3] and task assignment poblems [4]. 3. PSO BASED OPTIMIZATION OF LENGTH AND WIDTH OF THE ANTENNA The objective of the paticle swam optimization in this wok is to optimize the length and width of the poposed antenna. 3.1 Veification of pso Using Rosen Bock function In mathematical optimization, the Rosen bock function is used as a pefomance test poblem fo optimization algoithm. In ode to analyze the pso benchmak function is used in expeiment, whose equation is given as in equation (4) [14]. f ( x, y) ( a x) b( y x ) (4) Equation (4) above has global minimum at (x, y) = (a, a ) whee f(x, y) = 0. Usually these paametes ae set such that a = 1 and b = 100. Only the tivial case whee a = 0 is the function symmetic and the minimum at the oigin. The ange selected fo optimization of paamete is as follows: Width of the patch: 0.1mm to mm Length of the patch: 0.1mm to mm The effective length and width of the patch is evaluated using the below equation (v) Value = ( 1000 u) ( 1000 v) (v) Whee u and v stand as length and width of the patch 4. ANTENNA GEOMETRY The geomety of the poposed antenna is pesented in table 1 below. Initially the antenna was designed with defected gound stuctue at the cente of the gound but the esult we ae having was a single band then we emoved the DGS in ode to have multiband fequencies. The design paametes is summaized in table I also the length and patch of the poposed antenna was calculated using the below equations [15]. P L P w F C (6) C (7) F In (6) and (7), P L is the Length of the patch, P W is the 8 Width of the patch, C is the Speed of light as 3 10 m/s, F is the Solution fequency, is the Dielectic constant o pemittivity of the mateial.
