Title:OptimizationDesignofPolarizedPlanarUltra-WidebandModularAntennaArray
Abstract:
Inrecentyears,thedemandforhigh-speedwirelesscommunicationsystemshasrapidlyincreased,leadingtotheneedforefficientandversatileantennadesigns.Thispaperproposesanoptimizationdesignforapolarizedplanarultra-widebandmodularantennaarray.Theprimaryobjectiveistoenhancetheperformanceoftheantennaarrayintermsofbandwidth,radiationpattern,andpowertransmission.
1.Introduction
Theincreasingdemandforwirelesscommunicationsystemshasnecessitatedthedevelopmentofefficientantennadesigns.Theuseofantennaarrayshasbecomepopularduetotheirabilitytoprovideenhancedperformanceintermsofgain,directivity,anddiversity.Theplanarultra-widebandmodularantennaarrayhasgainedsignificantattentioninrecentyearsduetoitscompactsizeandversatility.Thispaperfocusesontheoptimizationdesignofapolarizedplanarultra-widebandmodularantennaarraytoimproveitsperformance.
