We are evaluating antenna options for a small RF device. This project is to etch and place a 50 ohm impedance 700 Mhz center frequency antenna on a surface area limited to 14 mm x 9 mm. Outside that 14 x 9 mm surface area, say in the 10 mm adjacent to the actual etched antenna, we want a standard [login to view URL] male connector to interface with RF test equipment. You can pick the PCB materials, etched line thickness, plating metal, etc. in order to optimize performance. We want 3 pieces of this small antenna. Boards will be shipped to US location.

Hello. There is an experience of using miniature antennas in the range of 700-900 MHz. However, you can place only a ceramic chip antenna on the area you specified. The effectiveness of its work will depend on the size of the landfill. The total size of the PCB = antenna area (14 * 9) + the area of the landfill (for example 40 * 60mm, you can place electronic components). We can make the design of the board, calculate the matching circuit, perform measurements of WSVR, return losses.

Hi, I have experience with Small antennas design. This antennas have several constraint due to him small size, i can cite low gain, small bandwidth. I have knowledge on miniaturization techniques, also, some of the more use antenna type there are the IFA and the MIFA antennas that i can to implement for you, i understand that you want an etched antenna on the PCB, however use a 3D structure can improve the gain. For improve the match with the RF device we can use a broadband impedance matching network too. I can understand that this antenna is only for testing, and not will be an internal antenna within a enclosure and i only need to design it on a PCB with the connector, however if the antenna will be used as an internal antenna after, the enclosure can affect the resonance frequency shifting it, and for that is possible put a self resonant antenna at 700 MHz with and section for an impedance matching network for that you can solve the problem of the future presence of a enclosure, maybe, it can be a second project o a part of the same in where i design an self resonant antenna taking into acoount the presence of the enclosure. The steps for solve this problem are: 1.) To talk with the employer for to obtain more details like the situation of use, technology, direction in where is spected that the antenna work, time for to implement. 2.) To make a project documentation for scheduling the time. 3.) To design the antenna with EM simulation, i can use FDTD EM simulation or

Hello! I'm currently working as a Microwave/RF engineer experienced in telecommunication antenna designing. As your description above, I think it's preferable to use chip antenna instead of pcb one in this area. Message me to discuss more about your antenna. Thank you for your attention! Best regards Luke
